ABB MCRC-0-22-AT-WL Industrial Control Relay Module

ABB MCRC022ATWL Mini Contactor Relay is a compact, four‑pole control device with 2 normally open and 2 normally closed contacts, designed for space‑constrained control circuits in residential, commercial, and industrial environments. It is specified with a nominal DC coil of 125 V (±30%), enabling reliable actuation from standard control power supplies, and it is rated for a conventional auxiliary circuit current of 10 A, with typical control signaling capable up to 6 A at 240 V AC‑15. The unit’s dimensions are 48 × 45 × 68 mm (H × W × D), and it uses screw terminals with a recommended tightening torque of 0.8–1.0 N·m, ensuring secure, vibration‑tolerant wiring in panel installations. This miniature contactor relay combines space efficiency with robust switching for control circuits and signaling in automatic systems, offering a practical solution when higher performance must fit within compact enclosures. Its four‑pole configuration and dual NO/NC contacts provide versatile wiring options for interlocking, sequencing, and isolation tasks in compact control panels and equipment racks.
