That AC-3 rating means it's built for switching squirrel-cage motors — starting, stopping, and inching under load — not just resistive heating or lighting. The coil pulls 220 V AC at 50 Hz, so it's a direct fit for European-standard control circuits without a transformer. For a 400 V supply, that typically covers motors up to about 160 kW, but always check the motor FLA against the AC-3 current at your line voltage. The contactor also carries an AC-1 rating for resistive loads — useful for large heating banks or lighting panels where the inrush is low. Auxiliary contacts are built in: 2 NO + 2 NC, which is enough for a standard three-wire start/stop circuit with one spare NO for a status signal back to the PLC. No separate aux block needed for basic control schemes. This contactor is part of the TeSys B range, designed for panel mounting on a backplate or DIN rail with the appropriate adapter. The 3-pole power circuit handles motor feeders, and the 220 V AC coil means the control transformer is already sized for that voltage. If your panel runs 24 V DC controls, you'll need an interposing relay or a different coil variant.","metaTitle":"TeSys CV1BH3H0ZM522 Contactor, 3P, 300 A AC-3, 220 VAC Coil","metaDescription":"Schneider TeSys CV1BH3H0ZM522 contactor, 3 poles, AC-3 300 A at 690 V, 220 V AC 50 Hz coil, 2 NO + 2 NC aux.

If your control voltage differs (e.g., 24 V DC or 380 V AC), the same BH frame with a different coil code is the direct alternative. No pin-compatible drop-in from another family exists — stick with the TeSys B BH frame for the same footprint and aux contact arrangement."},{"question":"What utilisation categories does this contactor cover?","answer":"It is rated for AC-1 (resistive loads like heating and lighting) and AC-3 (squirrel-cage motors: starting, stopping, inching)."},{"question":"What are the auxiliary contact specifications?","answer":"Built-in 2 NO + 2 NC auxiliary contacts, enough for basic control circuits without an add-on block."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/CV1BH3H0ZM522","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/CV1BH3H0ZM522 when reusing this data.
