BMDR-250 — WEG BMDR Moulded Case Circuit Breaker
The WEG BMDR Moulded Case Circuit Breaker (MCCB) is a robust, thermomagnetic protection device covering the current range from 63 A to 630 A in a compact moulded case housing, available in variants BMDR-63, BMDR-125, BMDR-250, BMDR-400, and BMDR-630. Designed for installation in low-voltage distribution switchboards, motor control centres (MCCs), and industrial panels, the BMDR provides overcurrent, short-circuit, and earth-leakage protection in a single device. In Saudi Arabia's industrial and commercial sectors, the BMDR is widely deployed in factory distribution boards, pumping station MCCs, commercial building main distribution frames, and utility sub-stations serving manufacturing sites in Jubail, Yanbu, and Riyadh's industrial zones. Its DIN-rail and fixed-mount options simplify panel assembly for Saudi panel builders working under SEC and MOMRA specifications.
The BMDR range is designed and tested to IEC 60947-2, the international standard for low-voltage circuit breakers, with short-circuit breaking capacity of up to 50 kA at 415 V for the higher-rated variants. The BMDR-250 and BMDR-400 are equipped with adjustable thermal and magnetic trip units, allowing site engineers to fine-tune the protection characteristic to the connected load without replacing the breaker. Rotary handle accessories, shunt trips, under-voltage releases, auxiliary contacts, and door interlocks are available as modular add-ons, making the BMDR fully compatible with Saudi panel builders' standard accessory specifications. Creepage and clearance distances exceed IEC 60664-1 requirements for Pollution Degree 3, suited to the dusty, high-humidity coastal environments of Dammam and Jeddah.
In the Saudi market, compliance with SASO GSO IEC 60947-2 is a procurement requirement for distribution equipment used in SEC-connected facilities and government projects. The WEG BMDR carries IEC type-test certificates from KEMA and other internationally recognised test houses, satisfying SASO and Baladiya import clearance requirements without additional local testing. Major contractors and panel builders serving ARAMCO, SABIC, Saudi Electricity Company, and the National Water Company include the BMDR in their approved vendor lists. The breaker's thermal withstand capability and 50°C ambient rating ensure reliable operation in Saudi Arabia's summer conditions without derating of the thermal trip, preventing nuisance tripping in hot panel rooms.
Razz Middle East stocks the WEG BMDR range across all five frame sizes — BMDR-63, BMDR-125, BMDR-250, BMDR-400, and BMDR-630 — along with the full complement of accessories including rotary handles, shunt trips, and auxiliary contacts. Quotations are issued in SAR within four hours of enquiry, with delivery to Riyadh, Dammam, Al Khobar, Jubail, Jeddah, and Yanbu achievable within 2–3 working days from local stock. Our technical team provides application support for breaker sizing, discrimination studies, and panel layout advice to Saudi panel builders and engineering consultants.

Key Features & Benefits
- Five frame sizes (BMDR-63 to BMDR-630) covering 63 A to 630 A in a consistent modular housing allow standardisation across distribution board and MCC designs.
- Adjustable thermomagnetic trip units on BMDR-250/400/630 enable field calibration to the connected load characteristic without breaker replacement, reducing spare-parts inventory.
- Short-circuit breaking capacity up to 50 kA at 415 V (IEC 60947-2 tested) protects downstream equipment in high fault-level industrial and utility distribution systems.
- Comprehensive accessory range — shunt trip, under-voltage release, auxiliary contacts, alarm contacts, rotary handle, and door interlock — integrates into any panel builder's standard design.
- 50°C ambient rating with IEC Pollution Degree 3 creepage distances ensures reliable operation in Saudi Arabia's hot, dusty industrial environments without derating.
Industrial Applications in Saudi Arabia
- Main and sub-distribution boards in industrial plants across Jubail and Yanbu industrial cities, providing coordinated overcurrent protection in compliance with SEC distribution codes.
- Motor control centre incomer and feeder breakers at NWC pumping stations and ARAMCO utility buildings, with adjustable trip settings matching motor FLA ratings.
- Commercial building distribution frames in Riyadh and Jeddah high-rises, where compact DIN-rail mounting saves panel space and the 50°C ambient rating suits mechanical plant rooms.
- Generator set output protection and bus-tie breakers in diesel generator panels for off-grid facilities and emergency power systems across the Kingdom.
- Solar PV combiner box and AC distribution protection in utility-scale solar farms and rooftop systems, with 4-pole versions providing neutral protection on TN-S systems.
