ABB MCRC-0-22-AT-D is a four-pole miniature contactor relay in ABB’s MCRC family, designed to switch motor control circuits in industrial automation. It provides two normally open and two normally closed contacts and is driven by a 24 V DC coil, enabling compact control logic for interlocks, sequencing, and control of small motors or actuators. Documented in ABB catalogs with the order code 1SAH100026R9900, the MCRC-0-22-AT-D is intended for panel-mounted installation in automation and motor-control applications such as conveyors, pumps, and other equipment that require reliable NO/NC switching.
