The 3-pole configuration with 3 NO main contacts matches a three-phase motor circuit, and the 220 V AC 50 Hz coil pulls in reliably at nominal line voltage. For a 630 A motor load, expect the panel to need busbars or cable lugs sized for the continuous current, and the contactor's physical size will drive the DIN-rail spacing and gland-plate fill. ## Coil and auxiliary contact layout Coil is 220 V AC 50 Hz only — no dual-frequency or DC option on this variant. The auxiliary contact block ships with 2 NO + 2 NC, enough for a holding circuit plus a status feedback to the PLC without adding a separate aux block. If your BOM calls for more than four aux contacts, you'll need the add-on block, but the base complement covers most motor starter schemes. The AC coil draws a sealed current that is low enough to be driven by a standard PLC relay output, but check the inrush at pick-up if the PLC card is marginal. The CV1BK3K0ZM522 belongs to the TeSys B family, the heavy-duty contactor range for high-current motor and resistive loads. The 'BK' current rating code maps to 630 A in AC-3, placing it above the TeSys D and F ranges.","metaTitle":"TeSys CV1BK3K0ZM522 Contactor, 630A AC-3, 220V AC Coil","metaDescription":"Active TeSys CV1BK contactor, 3-pole, 630 A rated operational current in AC-3 at 690 V, 220 V AC 50 Hz coil.
