Rated for the motor line
The CV1BJ3J0ZM522J is a 3-pole contactor from the TeSys B range, rated 470 A in AC-3 duty at 690 V AC. That AC-3 rating governs switching of squirrel-cage motors — starting, stopping, and inching under load. The 470 A figure is the current the main poles can make and break across the motor starting profile, not a resistive heating limit. For resistive circuits, heating, and lighting, the same contactor carries an AC-1 utilisation category, which typically permits a higher continuous current. Control circuit is 220 V AC at 50 Hz, specified as the coil voltage. The contactor pulls in on that AC control supply; the built-in auxiliary contacts include one C/O on-delay timer contact plus two instantaneous NO and two NC contacts. That on-delay gives you a programmable interval before the auxiliary switches — useful for star-delta transition or staggered load sequencing without an external timer relay.
The TeSys B frame is a DIN-rail-mounted contactor family. At 470 A AC-3, the physical package is substantial — expect the panel builder to allocate adequate side clearance for arc-chamber ventilation and power-wiring bend radius. The 3-pole configuration with 3 NO main poles covers three-phase motor circuits. Auxiliary contact wiring (2 NO + 2 NC instantaneous, plus the timed C/O) should be terminated with ferruled stranded conductors matching the terminal strip pitch.
