Description
The LS Electric MC-22B is a 3-pole IEC contactor in the Metasol MC B-series, fitted with a 110V AC control coil (50/60 Hz). This contactor is the LS Electric-designated replacement for the obsolete GMC-22 series and is also cross-referenced as MC22B-30-11. Refer to manufacturer documentation to confirm compatibility with your specific application.
This contactor carries a rated operational current of 22A under AC-3 duty (40A under AC-1) and is rated for 15 HP at 460V three-phase. It ships with 1 Normally Open (NO) and 1 Normally Closed (NC) auxiliary contact built in as a single side-mounted block — no add-on auxiliary block required for basic control logic. Main contacts are 3-pole NO, with screw clamp terminals, and the unit mounts on a 35mm DIN rail or panel backplate.
The MT-32 series thermal overload relay (40AF frame) mounts directly to the T1-T2-T3 load terminals of the MC-22B for a complete motor starter assembly. Additional front- or side-mounted auxiliary contact blocks are available for more complex control schemes.

About ACME MRO Solutions
We started ACME MRO Solutions to fix something we kept running into as contractors — plants down, parts slow, surplus listings you couldn't trust. Our goal is simple: get YOU the right component fast, with an honest description, so you can get back to running.
We describe what we see. Used items show signs of use; if a part has visible wear, damage, or a missing component, the condition description will say so. We don't claim anything is tested unless we tested it — and we don't bench-test parts where testing isn't practical or revealing (feed-through modules, breakers, mechanical components). When we do test something, we'll say so explicitly.
If something is our fault, we don't work through it — we make it right. We are proud to serve American manufacturing. Your uptime is our bottom line.
