That AC-3 utilisation category means it's designed for switching squirrel-cage induction motors — making and breaking currents during starting, stopping, and inching. It also carries an AC-1 rating for resistive and heating loads, so it can handle lighting banks or oven elements without derating. The contactor is built with a single normally-open main pole and a full auxiliary contact complement of 2 NO + 2 NC, giving you feedback and interlocking capacity without an add-on block. At 630 A AC-3, this is a heavy-duty single-pole unit — think large motor loads, resistance welding transformers, or high-current resistive banks where you need one line switched and the other two pass-through. This is a panel-mount contactor, not a DIN-rail snap-on. The TeSys B frame at this current rating is bolted to a backplate or mounting chassis. Plan for busbar or cable connections rated for the full 630 A continuous — the contactor itself is compact for its rating, but the incoming and outgoing conductors need space and bend radius. The 2 NO + 2 NC auxiliary contacts are wired separately from the main power circuit. Use them for PLC feedback, seal-in circuits, or status indication to the control system. The coil circuit is 220 V AC — verify your control transformer matches before commissioning.","metaTitle":"TeSys CV1BK1K0ZM522 Contactor, 1P, 630A AC-3, 220VAC Coil","metaDescription":"Schneider TeSys B CV1BK1K0ZM522 1-pole contactor, 630 A AC-3 at 690 V, 220 V AC 50 Hz coil.
