Why Choose the ABB MCRC022ARWID-RAIL Mini Contactor Relay?
The ABB 1SAH102145R9910, type MCRC022ARWID-RAIL, is a compact four-pole mini contactor relay designed for control functions and switching small electrical loads in demanding industrial and railway applications. Part of ABB’s MCRC...R-RAIL range, its dimension-optimised construction provides high switching performance where installation space is limited.
The MCRC022ARWID-RAIL features two normally open and two normally closed contacts (2NO + 2NC) together with special screw terminals for connection using ring-tongue ferrules. Its DC-operated control circuit is specified for a 51–90 V DC control voltage range, with a nominal 72 V DC designation.
Designed for switching control signals and small loads up to 6 A at 240 V AC in AC-15 applications, the MCRC022ARWID-RAIL combines compact dimensions with secure electrical connections. It is suitable for rail or wall mounting and is designed for railway environments, including shock and vibration requirements according to IEC/EN 61373 and fire and smoke requirements according to EN 45545-2.

Compact Control Switching for Railway and Industrial Systems
Mini contactor relays such as the ABB MCRC022ARWID-RAIL provide multiple electrically operated contacts for switching control signals and small loads. Its 2NO + 2NC arrangement enables normally open and normally closed circuits to change state simultaneously when the DC-operated contactor relay is energised.
The MCRC...R-RAIL range is designed for applications requiring compact dimensions, secure ring-tongue connections and resistance to railway operating conditions. The MCRC022ARWID-RAIL can be mounted on a rail or wall and supports additional front- or side-mounted auxiliary contact blocks where extra control contacts are required.
Typical Applications
- Railway and rolling-stock control systems.
- Industrial machinery control circuits.
- Automation and control panels.
- Switching of control signals and small electrical loads.
- Transport electrical systems.
- OEM machinery and compact electrical control assemblies.
