MDW-C16 — WEG MDW Miniature Circuit Breaker
The WEG MDW Miniature Circuit Breaker (MCB) is a compact, DIN-rail-mounted overcurrent protection device covering rated currents from 1 A to 63 A in 1P, 2P, 3P, and 4P configurations, with tripping characteristics B (general lighting and resistive loads), C (standard inductive loads and motor protection), and D (high-inrush transformers and solenoid applications). The MDW is the workhorse of WEG's low-voltage switchgear portfolio, found in final distribution boards across residential, commercial, and light industrial projects throughout Saudi Arabia. From villa distribution boards in Riyadh's new housing developments to lighting panel boards in NEOM's hospitality facilities and retail circuit protection in Red Sea Project resort complexes, the MDW's reliable performance and competitive pricing make it the natural choice for Saudi electrical contractors and panel builders supplying SEC-metered installations.
The MDW MCB is designed and tested to IEC/EN 60898-1 (household and similar applications) and IEC 60947-2 (industrial applications), providing dual compliance for projects where both domestic and industrial standards are cited in specifications. Breaking capacity is 6 kA at 230/400 V for standard variants and 10 kA for the MDW-H high-breaking-capacity series, meeting the fault level requirements of most Saudi distribution networks. The MDW's DIN-rail pitch is compatible with standard 35 mm rails and matches WEG's RCBO, RCD, and surge protection device accessories, allowing integrated assembly in compact boards. Operating temperature range extends to 55°C, and the device is rated for 20,000 mechanical and 10,000 electrical operating cycles, ensuring reliable service life in harsh Saudi environments.
SAMO (Saudi Standards, Metrology and Quality Organization) and SASO import requirements for MCBs mandate compliance with GSO IEC 60898-1 or equivalent IEC 60947-2 type-test certification. The WEG MDW holds CE marking and IEC type-test certificates from accredited laboratories, satisfying Saudi Customs clearance and Baladiya approval requirements for use in SEC-connected distribution systems. Saudi panel builders and electrical contractors supplying Riyadh's booming residential sector — including projects under the Ministry of Housing's Sakani programme and major developers such as ROSHN — routinely specify the MDW for its cost-effectiveness, reliable type-test documentation, and WEG's established local distribution network through Razz Middle East and other authorised distributors across the Kingdom.
Razz Middle East maintains comprehensive stock of the WEG MDW range across all pole configurations (1P to 4P), current ratings (1 A to 63 A), and tripping characteristics (B, C, D), enabling same-day or next-day fulfilment for most orders. We supply MDW breakers individually or in carton quantities to electrical wholesalers, panel builders, and EPC contractors across Saudi Arabia. Pricing is quoted in SAR per unit and per carton with volume discount brackets. Technical datasheets, type-test certificates, and SASO compliance documentation are available on request from our Riyadh and Dammam offices.

Key Features & Benefits
- Three tripping characteristics — B (resistive), C (inductive/motor), D (high-inrush) — cover the full range of load types in residential, commercial, and light industrial distribution boards.
- Dual standard compliance with IEC/EN 60898-1 and IEC 60947-2 satisfies both domestic wiring and industrial panel specifications in a single device, simplifying procurement.
- 10 kA breaking capacity on MDW-H series handles fault levels in high-fault-level commercial and industrial distribution networks without requiring a separate current-limiting fuse.
- 35 mm DIN rail mounting compatible with WEG RCBO, RCD, and surge protection device accessories enables integrated board assembly in compact enclosures.
- 55°C ambient operating temperature rating ensures reliable tripping accuracy in Saudi Arabia's hot distribution board environments where internal temperatures commonly exceed 45°C.
Industrial Applications in Saudi Arabia
- Final distribution boards in residential villas and apartment complexes under the Sakani housing programme and ROSHN developments across Riyadh, Jeddah, and the Eastern Province.
- Lighting and small power circuit protection in commercial office buildings, retail centres, and hotels throughout Saudi Arabia's major cities.
- Sub-distribution boards in light industrial factories and workshops in Second Industrial City (Riyadh) and Dammam Industrial City, using C-curve variants for motor branch protection.
- Temporary power distribution boards on construction sites for giga-projects including NEOM, Red Sea Project, and Diriyah Gate development.
- Control panel branch circuit protection in machine tools, packaging lines, and food processing equipment manufactured or assembled in Saudi Arabia.
