Compact Switching for Railway and Industrial Systems
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.
Typical Applications
- Railway rolling stock electrical systems.
- Passenger and driver compartment electrical equipment.
- Single-phase and three-phase load switching.
- Three-phase motor control.
- Resistive load switching.
- Compact railway and industrial control panels.
