The Schneider Electric CV1BH2H0ZMD11 is a 2-pole contactor from the TeSys B series, rated for 300 A in AC-3 duty at 690 V AC. That AC-3 rating governs motor switching — it handles the inrush and breaking of induction motors up to that current. The same contactor also carries an AC-1 rating for resistive loads like heating banks, where switching is less stressful on the contacts. The coil is 220 V DC. Verify your control voltage matches before wiring. Contact configuration is 2 NO main poles plus 1 NO + 1 NC auxiliary contact block integrated into the device. That auxiliary set is enough for a basic feedback or interlock loop without adding a separate block.
The 2-pole design limits it to single-phase or DC switching, or two legs of a three-phase motor with a third pole handled externally. For three-phase motor duty, a 3-pole or 4-pole contactor is the standard choice.
