The Schneider Electric TeSys B CV1BG3G0ZM532 is a 3-pole contactor rated for 200 A at 690 V AC, covering AC-3 motor switching and AC-1 resistive loads like heating and lighting circuits. The auxiliary contact block (3 NO + 2 NC) is built in, so you don't lose a slot on the DIN rail for feedback or interlock wiring.
At 690 V AC it handles the higher line voltage common in 400 V three-phase systems with headroom for voltage drop. The AC-1 rating for resistive loads is higher, but the AC-3 figure is the one that decides whether the contactor holds in on a compressor or conveyor start. The 220 V AC 50 Hz control coil is a fixed-voltage type — no electronic coil interface, so it pulls in hard and drops out cleanly. That matters for panels where the control transformer is already sized for AC solenoids; you don't need a separate DC supply for this contactor bank.
Where it lands in the TeSys family
This is a TeSys B standard contactor — the workhorse line for motor switching up to 200 A. It sits between the smaller TeSys D frame (up to 65 A typically) and the larger TeSys F or LC1F frames for heavy-duty applications. The 'BG' current rating code places it at the upper end of the TeSys B range, so it's sized for a 90–110 kW motor at 400 V depending on duty cycle.
