The Schneider Electric TeSys B CV1BK1K0ZMR32J is a 1-pole DC contactor rated for 630 A AC in the power circuit, with a 220 V DC control coil. It is designed for DC-3 utilisation category, meaning it handles the high inrush of DC motor starting and plugging, as well as resistive and heating loads.
Auxiliary contact complement
This contactor carries an auxiliary contact block with 3 NO + 2 NC instantaneous contacts plus one C/O on-delay contact. That's enough for a basic interlocking and status feedback scheme without an add-on block — useful when panel space is tight and you want to keep the wiring tidy.
