The CV1BG2G0ZM510J is a Schneider Electric TeSys B contactor, part of the broader TeSys range. It is a 2-pole device with normally open main contacts, rated for 200 A at 690 V AC in both AC-1 (resistive) and AC-3 (motor) duty categories. That 200 A rating is the operational current for the power circuit — meaning it can handle motor starting currents within the AC-3 curve, not just steady-state resistive loads. The coil is 220 V AC at 50 Hz, so verify your control voltage matches before wiring.
This is a panel-mount contactor sized for motor control or resistive heating circuits. The 2-pole configuration with 2 NO main contacts means it switches both lines on a single-phase load or two phases of a three-phase motor. The auxiliary contact block has 1 NO built in — enough for a seal-in circuit or status feedback, but if you need more aux contacts, you'll add a side-mount block.
