The ABB MC2C400ATWJD-RAIL 1SAL102109R9912 is a compact, dimension-optimised four-pole DC-operated mini contactor designed for reliable switching in railway rolling stock and industrial electrical systems. Featuring 4 normally open (NO) main contacts, it provides four-pole load switching in applications where high performance and efficient use of installation space are important.
Developed as part of the ABB MC2C-RAIL mini contactor range, the MC2C400ATWJD-RAIL uses screw terminals and incorporates a diode in its DC-operated control circuit. It is designed in accordance with applicable parts of IEC/EN 60077 and provides shock and vibration resistance in accordance with IEC/EN 61373 Category 1, Class B.
With a rated operational power of 5.5 kW at AC-3, 400 V, a rated operational current of 12 A at AC-3, 400 V and an AC-1 rating of 20 A at 400 V, the MC2C400ATWJD-RAIL provides capable switching performance for motors and resistive loads. Its control circuit operates across 77–137 V DC, corresponding to a 110 V DC railway control system, and the contactor is suitable for rail or wall mounting.
Mini contactors provide electrically controlled switching of power loads while occupying less installation space than conventional contactors. The ABB MC2C-RAIL range combines compact dimensions with DC operation, an integrated diode and robust railway-focused construction for controlling small motors and resistive loads.
The MC2C400ATWJD-RAIL is designed for demanding rolling stock environments and provides four normally open main poles for switching single-phase or three-phase loads. Its resistance to shock and vibration, compliance with railway fire and smoke requirements and suitability for rail or wall mounting make it a practical switching solution for railway and industrial control systems.
