The TeSys B CV1BK2K0ZM522 is a 2-pole contactor rated for 630 A in AC-3 duty at 690 V AC, meaning it handles motor switching up to that current level — the AC-3 category covers starting and stopping squirrel-cage motors under full load. The same power circuit also carries an AC-1 rating for resistive loads like heating and lighting, where the current is non-inductive. The control coil is 220 V AC at 50 Hz, a standard mains-voltage coil for direct panel wiring without a separate control transformer. The contactor is built with 2 normally-open main poles and carries a factory-fitted auxiliary contact block with 2 NO + 2 NC contacts, giving you feedback or interlocking capability without an add-on module. It belongs to the TeSys B range, which is the global heavy-duty contactor family from Schneider Electric.

Product details
Frequently asked questions
What is the utilisation category and what loads does it suit?
It is rated AC-3 and AC-1. AC-3 covers motor starting and stopping under load; AC-1 covers resistive loads such as heating and lighting circuits.
What is the control coil voltage and frequency?
The coil is 220 V AC at 50 Hz, a standard mains-voltage control circuit for direct connection without a step-down transformer.
What auxiliary contacts are included?
It comes with 2 normally-open and 2 normally-closed auxiliary contacts factory-fitted, providing feedback and interlocking without an add-on block.
