The Schneider Electric CV1BL2L0ZM511 is a TeSys B contactor, 2-pole, rated 1000 A in AC-3 duty at 690 V AC — so it handles heavy motor switching and resistive loads like heating banks or lighting circuits up to that current. Coil pulls in on 220 V AC 50 Hz. AC-1 covers resistive circuits at the same current.
Contact configuration and auxiliary contacts
Main poles are 2 NO. Auxiliary contact block carries 1 NO + 1 NC, enough for basic interlocking or status feedback without adding a separate aux block. Control circuit is AC, so verify the coil voltage matches the panel supply — 220 V AC 50 Hz is the listed control voltage.
