Description
About the LC1K
About the LC1K
The Schneider Electric LC1K0910E7 is a 3-pole TeSys K mini contactor rated 9 A AC-3 at up to 440 V (4 kW at 400 V), with a 1NO built-in auxiliary contact. It runs on a 48 V AC 50/60 Hz coil, connects via screw clamp terminals, and fits a 45 mm DIN-rail or plate-mount footprint rated to 3600 cyc/h.

Selection Notes
The 9 A AC-3 rating sizes this contactor for a 4 kW motor at 400 V; step up to a higher-current TeSys K frame, or to TeSys Deca once past 16 A, for larger motors. The 1NO auxiliary contact is fixed at the factory and cannot be field-changed, so confirm the control-circuit logic needs 1NO before ordering rather than after. The 48 V AC coil is one of several control-voltage options in the same LC1K09 frame — match it to the transformer or line voltage already feeding the panel's control circuit.
