Part identity and ratings
The Schneider Electric TeSys B contactor CV1BF2F0ZF522 is a 2-pole (2 NO main poles) device rated for 80 A operational current in AC-3 duty at 690 V AC. The coil pulls in on 110 V AC at 50 Hz. It also carries an AC-1 utilisation category for resistive loads like heating and lighting circuits.
The 80 A AC-3 rating is the motor-switching current — it governs the largest three-phase induction motor this contactor can handle under starting and stopping duty. The 110 V AC coil is standard for North American control transformers; verify your control voltage matches before wiring.
Auxiliary contacts and integration
Built-in auxiliary contacts are 2 NO + 2 NC, enough for a holding circuit plus one feedback signal to a PLC input without an add-on block.
