WEG DOL Starter Assembly MPW-40 + CWM25 (up to 2.2 kW)
The WEG DOL Starter Assembly combining the MPW-40 motor protection circuit breaker with the CWM25 contactor provides a complete, pre-wired and tested direct-on-line motor starter for three-phase motors up to 2.2 kW (3.0 hp) at 400 V AC. This combination is one of the most popular DOL starter assemblies for Saudi industrial MCCs, covering a motor size extensively used in building services, utilities, and light process equipment throughout Saudi Arabia.
Technical Assembly Details
Components: MPW-40-3-D040 (3.2–4.0 A) MPCB matched to 2.2 kW motor FLC, CWM25 AC-3 contactor rated 25 A, control relay for SCADA feedback, local isolator capability via padlockable MPCB handle, and DIN-rail sub-plate with clearly identified terminal points. The assembly is factory wired using colour-coded conductors per IEC 60446 (matching Saudi Aramco wiring colour standards) and tested for correct electrical operation before delivery.
IEC Coordination and Saudi Specifications
Type 2 coordination is confirmed for MPW-40 + CWM25 at 100 kA at 400 V, meeting the requirements of Saudi Aramco and SABIC MCC specifications for motor branch circuit protection and switching device coordination. The higher breaking capacity of the MPW-40 frame (100 kA) compared to MPW-25 (50 kA) makes this assembly suitable for installation closer to LV main distribution boards where fault levels are higher — an important consideration for large Saudi industrial plants with high available fault current at the MCC busbars.
Saudi Industrial and Infrastructure Applications
The 1.5–2.2 kW range covers motors for primary and secondary chilled water pump auxiliaries in large building management systems, sewage transfer pump starters at industrial facilities and hotels, air compressor loading valve actuators, and fire hydrant booster pump auxiliaries per NFPA 20. Saudi Aramco's new giga-projects and existing facility upgrades both utilise WEG DOL starter assemblies, and Razz Middle East's local Saudi inventory enables delivery within 24–72 hours for urgent project requirements.
