Specifying a circuit breaker in KSA without confirming breaking capacity, pole count, and tripping characteristic against the actual fault current the installation can produce is the single most common design error - an MCB rated for a residential distribution board and an air circuit breaker rated for a 6300A main incomer are not interchangeable, and undersizing breaking capacity leaves a breaker unable to safely interrupt a real short-circuit fault. This guide covers every circuit breaker type stocked by circuit breaker suppliers in KSA - Moulded Case Circuit Breakers, Air Circuit Breakers, ABB Circuit Breakers, Ex-Proof Circuit Breakers, and Vacuum Circuit Breakers - along with technical specifications, brand comparisons, and named suppliers across Riyadh, Dammam, and Khobar.
Six circuit breaker suppliers in KSA, all based in Riyadh - use the "Why Choose" section under each to match the supplier to your project before you call.
Address: Prince Mohammed Bin Abdulrahman Bin Abdulaziz Road, Riyadh, KSA | Phone: +966 55 947 1701 | Mobile: +966 54 802 2461
HARMATEK is based on Prince Mohammed Bin Abdulrahman Bin Abdulaziz Road in Riyadh and carries an independently verified supplier status, giving buyers extra confidence before ordering. Its range weights toward the more specialised end of the circuit breaker market - DC-rated, dual AC/DC rated, and mission-critical breakers - which distinguishes it from suppliers carrying only standard AC distribution breakers, and matters specifically for solar, battery storage, and critical-facility projects where a standard breaker isn't rated for the fault-interruption duty required.
Address: Al Madinah Munawara Road, Al Faisalia, Riyadh, KSA | Phone: +966 54 705 2578 | Mobile: +966 56 500 2275
Samaa Al Hilal Company operates from Al Faisalia in Riyadh and carries independently verified supplier status. Its product range covers the compact, high-volume end of the circuit breaker market - miniature circuit breakers for distribution boards and adjustable-setting MCCBs for feeder and sub-main circuits - the categories most commonly specified on residential, commercial, and light industrial electrical installations across the capital.
Address: Al Adl Al Waez, Al Amal, Riyadh, KSA | Phone: +966 54 991 4050
Mas Control Electric operates from Al Amal in Riyadh, and its company name and product focus both signal a specialisation in motor control and protection equipment specifically, rather than general electrical distribution components. This positioning matters for buyers sourcing motor protection circuit breakers where the trip curve needs to accommodate motor inrush current without nuisance-tripping, a requirement a general-purpose MCCB supplier may not stock a dedicated range for.
Address: Between Exits 5 & 6, Near King Abdulaziz Center for National Dialogue, Al Nafl, Riyadh, KSA | Phone: +966 11 494 5400
Alfanar is a well-known Saudi electrical equipment manufacturer, and its Riyadh location - between Exits 5 and 6 near King Abdulaziz Center for National Dialogue - carries independently verified supplier status. Buying the ALFANAR-branded MCB range directly rather than through a reseller means access to the full published technical specification set (impulse voltage, insulation voltage, IP ratings, short circuit cut-off current) rather than a partial spec sheet, which matters for engineers who need to check compliance against a project's electrical design standard before ordering.
Address: Tahliah Trading Centre, Al Hamdan Street, Riyadh, KSA | Phone: +966 11 463 3117
RS Components is a globally recognised industrial and electronic component distributor, and its Riyadh branch on Al Hamdan Street gives Saudi buyers local access to that global multi-brand catalogue rather than needing to import directly. Its circuit breaker range spans multiple international brands - ABB and Mitsubishi Electric among them - which is useful specifically for maintenance and repair work where the original installed brand needs matching, or for projects specifying a particular international brand for compliance or client-preference reasons.
Address: 7529 Ali Ibn Harun St, Al Muhammadiyah District, Riyadh 12363-3612, KSA | Phone: +966 11 470 5577
Al Marshad Trading Co is based in Riyadh's Al Muhammadiyah District and carries the broadest single-supplier spread in this guide - MCCBs, air circuit breakers, high-voltage protection breakers, and solar DC breakers - covering both standard AC distribution and the growing solar PV and DC protection segment of the Saudi market. This breadth matters for buyers on mixed-scope projects (a facility with both a conventional AC distribution board and a rooftop solar installation) who want one supplier relationship covering both rather than sourcing DC-rated breakers separately.

Schneider Electric's MasterPact range covers universal power circuit breakers and insulated case circuit breakers from 800A up to 6000A, engineered to protect electrical systems from overload, short-circuit, and equipment ground-fault damage. The range is certified across multiple international standards, which matters directly for Saudi projects that may follow a US-derived (ANSI/UL), Canadian (CSA), or IEC-based electrical design standard depending on the client and consulting engineer.
A side-by-side comparison of the main circuit breaker brands and types referenced across this guide.
| Brand / Range | Breaker Type | Current Range | Standard | Typical Application |
|---|---|---|---|---|
| Schneider PowerPacT H | MCCB | 100A (frame up to higher ratings) | 600VAC breaking voltage | Industrial/commercial distribution |
| Schneider EasyPact CVS | MCCB | Up to 800A+ | 415V AC | General industrial distribution |
| Schneider MasterPact NT/NW/MTZ | ACB / ICCB | 800-6000A | ANSI C37/UL1066/UL489, CSA, IEC 60947-2 | Main incomer, bus-tie, mission-critical facilities |
| ABB S200 | MCB | Up to ~63A (13A in profiled model) | IEC/EN 60898-1, IEC/EN 60947-2 | Motor and general distribution circuits |
| ALFANAR | MCB | 25A (profiled model) | IEC 60898-1 | Distribution boards, plug-in mount |
| MEMF ETIMAT 6 | MCB | 6A (profiled model) | - | Residential/light commercial |
| Mitsubishi Electric BH-D6 | MCB | 0.5-63A | IEC, CE, UKCA, CCC, DNV, CCS | Multi-standard compliance projects, marine |
| CHINT NA1 | ACB | 2500A (profiled model) | 380V AC | Main incomer, bus-tie |
| Himel | Motor Protection Breaker | 2.5-4A | - | Small motor circuits |
As a general pattern, MCB brands (ALFANAR, MEMF, Mitsubishi BH-D6, ABB S200) cover the 0.5A to roughly 63A range for distribution boards and final circuits, MCCB ranges (Schneider PowerPacT and EasyPact CVS) scale from around 100A up into the thousands of amps for feeders and sub-mains, and ACB ranges (Schneider MasterPact, CHINT NA1) start around 800A and scale to 6300A+ for main incomers and bus-ties. Standard and certification requirements (IEC, ANSI/UL, CSA) should be confirmed against the specific project's electrical design code before ordering, since a breaker's physical size and current rating being correct doesn't guarantee its certification matches what the project specification requires.
| Application | Recommended Breaker | What to Look For |
|---|---|---|
| Residential and light commercial distribution boards | MCB (B or C curve) | Current rating, pole count, tripping curve matched to load type |
| Industrial feeder and sub-main circuits | MCCB, adjustable-setting MCCB | Breaking capacity, trip unit type, adjustability |
| Main incomer and bus-tie | ACB (fixed or drawout, motorised where automated) | Current rating, certification (ANSI/UL/IEC), mounting style |
| Motor circuits | Motor protection circuit breaker (M-C characteristic) | Trip curve matched to motor starting current |
| Shock and earth fault protection | RCCB | Trip sensitivity (mA rating), current rating |
| Hazardous gas/dust area electrical installations | Ex-Proof Circuit Breaker | Zone classification match, gas group certification |
| Medium-voltage substation switchgear | Vacuum Circuit Breaker | Voltage class, interrupting capacity |
| Solar PV and battery storage DC circuits | Solar DC Circuit Breaker, DC-Rated Circuit Breaker | DC voltage rating matched to system, correct polarity marking |
| Mission-critical and data centre facilities | Mission Critical Circuit Breaker, ANSI Certified MasterPact | Reliability testing standard, certification documentation |
| Breaker Category | Price Range (SAR) | Main Price Factors |
|---|---|---|
| Miniature Circuit Breaker (MCB) | 15-95 | Current rating, pole count, brand |
| Residual Current Circuit Breaker (RCCB) | 80-350 | Current rating, trip sensitivity, brand |
| Molded Case Circuit Breaker (MCCB) | 150-3,500 | Current rating, breaking capacity, adjustability |
| Motor Protection Circuit Breaker | 120-650 | Current range, trip class |
| Air Circuit Breaker (ACB) | 4,500-45,000+ | Current rating, drawout vs fixed, motorised operation, certification |
| Ex-Proof / Vacuum Circuit Breaker | Project-specific, request quotation | Zone/voltage classification, certification, custom engineering |
Circuit breaker price in KSA scales primarily with current rating, breaking capacity, and certification level rather than physical size alone - an ANSI-certified or IEC-rated air circuit breaker with a motorised operator and communication module can cost many times a basic fixed-mount unit of the same current rating. Ex-proof and vacuum circuit breakers are typically quoted per project given the zone-specific certification and custom engineering involved.
The main categories are Miniature Circuit Breakers (MCB) for residential and light commercial circuits, Moulded Case Circuit Breakers (MCCB) for industrial feeders, Air Circuit Breakers (ACB) for main incomers and high-current switchgear, Residual Current Circuit Breakers (RCCB) for earth fault protection, motor protection circuit breakers, Ex-Proof circuit breakers for hazardous areas, and vacuum circuit breakers for medium-voltage switchgear.
An MCB (Miniature Circuit Breaker) typically covers up to around 63A with a fixed trip characteristic, correct for final sub-circuits. An MCCB (Moulded Case Circuit Breaker) covers a much wider current range - commonly 100A up to 3200A - often with an adjustable trip setting, correct for feeder and sub-main circuits carrying higher current than an MCB is rated for.
This guide covers six verified suppliers - HARMATEK, Samaa Al Hilal Company, Mas Control Electric, Alfanar, RS Components Ltd, and Al Marshad Trading Co - each carrying a different mix of MCB, MCCB, ACB, and specialised breaker stock. Compare their specific product ranges above against your requirement rather than assuming any one is universally "best."
Circuit breaker price in KSA ranges roughly SAR 15-95 for MCBs, SAR 80-350 for RCCBs, SAR 150-3,500 for MCCBs depending on current and breaking capacity, SAR 120-650 for motor protection breakers, and SAR 4,500-45,000+ for air circuit breakers depending on current rating and features. Ex-Proof and vacuum circuit breakers are typically quoted per project. Contact the supplier for a current quote on the specific model and quantity.
Whenever the installation area is classified as a hazardous zone due to flammable gases, vapours, or combustible dust - refineries, chemical plants, and similar facilities. Confirm the specific zone classification and gas group of the installation location, since the breaker's Ex certification must match that zone precisely rather than carrying a general Ex-proof marking.
An RCCB monitors the current balance between live and neutral conductors and trips on detecting an earth leakage fault - a fault current too small to trip a standard MCB but large enough to be dangerous to a person. It's mandatory or strongly recommended in bathrooms, outdoor sockets, construction site power, and other locations where personal shock protection is the priority.
Yes - a DC arc doesn't naturally extinguish at a current zero-crossing the way an AC arc does, so a DC-rated breaker needs a different arc-quenching design and current rating to safely interrupt a DC fault. Never substitute a standard AC-rated breaker onto a DC circuit such as a solar PV or battery storage system - specify a breaker explicitly rated for DC fault interruption at the system's actual DC voltage.
All six suppliers covered in this guide - HARMATEK, Samaa Al Hilal Company, Mas Control Electric, Alfanar, RS Components Ltd, and Al Marshad Trading Co - are Riyadh-based. Buyers in Dammam or Khobar should confirm nationwide delivery terms directly, particularly for Ex-Proof and industrial-grade breakers common on Eastern Province petrochemical projects.
