The Schneider Electric TeSys B CV1BL1L0ZM510J is a 1-pole contactor rated for 1000 A AC in AC-3 duty at 690 V, with a 220 V AC 50 Hz coil. That AC-3 rating means it's built for switching motor loads — starting, stopping, and inching induction motors under full load — up to that current. The AC-1 rating covers resistive loads like heating elements or lighting banks where the inrush is minimal.
Coil and auxiliary contacts
The control circuit is AC, 220 V at 50 Hz — no DC coil option here, so verify your control transformer taps. It carries one instantaneous NO auxiliary contact plus one on-delay contact, which is useful for sequencing a star-delta start or staging a downstream contactor without an external timer.
