The Schneider Electric TeSys B contactor CV1BG4G0ZM710J is a 4-pole power contactor rated for 200 A AC in the power circuit at 690 V AC. It is part of the TeSys range, a broadly deployed family for motor starting and resistive load switching in industrial control panels. Rated for utilisation categories AC-1 (resistive loads like heating) and AC-3 (squirrel-cage motors), it covers the two most common switching duties in a plant. The control circuit is 220 V AC, a standard coil voltage across European and many Asian installations. Auxiliary contacts are built in: 1 NO + 1 C/O, with one of those being an on-delay timing contact.
The 4-pole configuration (4 NO main poles) is useful for switching three-phase motor circuits plus a neutral, or for resistive loads where all four poles are needed. The 200 A frame size means it needs adequate clearance for cable bending radius and heat dissipation — plan for at least 50 mm of free air above and below the contactor when laying out the panel.
