Part identity and ratings
The Schneider TeSys B contactor CV1BL3L0ZM722 is a three-pole power contactor rated for 700 A in AC-3 duty (motor switching) and 1000 A in AC-1 (resistive) at 690 V AC. The control coil is 220 V AC 50/60 Hz. It carries 2 NO + 2 NC instantaneous auxiliary contacts, bolted power connections, and is intended for motor, resistive, and lighting circuits.
The AC-3 rating of 700 A at 690 V defines the motor switching capability — this contactor can handle a 375 kW induction motor on a 400 V supply (AC-3). The AC-1 rating of 1000 A covers resistive loads such as heaters or lighting banks. The 220 V AC coil is a standard control voltage in many industrial panels, but verify your control transformer output; a 50/60 Hz coil may draw higher inrush at 60 Hz. The 2 NO + 2 NC aux contacts are built in, so no separate aux block is needed for basic feedback or interlocking.
