ABB MCRC-0-31-AT-D Motor Circuit Relay Module

ABB MCRC-0-31-AT-D is a compact four-pole motor circuit relay (minicontactor) with a 24 V DC coil, designed for direct control of small motors in ABB control systems. It features three normally open and one normally closed contact (4 poles total) to support simple start/stop and interlock logic in 24 V DC control circuits. This DC-operated module carries ABB's order code 1SAH100016R9900 and has a shipping weight of about 0.235 kg per unit. Typically used with ABB overload relays and starter assemblies, the MCRC-0-31-AT-D is suitable for motor control tasks such as driving small conveyors, pumps, fans, and other machinery where compact, dedicated control relays are specified. The model belongs to ABB's MCRC family and is documented in ABB's motor control catalogs alongside related variants, offering a reliable solution for compact control of medium duty motors in 24 V DC control networks.
