Square D LC1K TeSys K 3-Pole IEC Motor Contactor, 110VAC Coil

Square D LC1K TeSys K 3-Pole IEC Motor Contactor, 110VAC Coil

The Square D TeSys K 3-Pole IEC Contactor is a compact motor-control contactor engineered for motor and resistive-load switching in commercial and industrial panels, available with Motor FLA (Ie) ratings from 9A to 12A AC-3 at up to 440V AC. Each 3-pole (3P) contactor in this family features a 110V AC 50/60Hz control circuit coil and 1 NO auxiliary contact for remote signaling and interlocking. It is backed by multiple third-party listings including UL, CSA, and CE, and conforms to IEC/EN 60947-4-1 for dependable performance in panel-building and OEM control applications. Select the Motor FLA rating that matches your motor and application load when ordering.

Key Features

• Rated Operational Current: 9A to 12A (Ie) AC-3 at ≤440V AC for the power circuit, selectable by Motor FLA.
