The LC1K09103K72 is a TeSys K series contactor from Schneider Electric, a 3-pole device rated for control applications. It carries a rated operational current of 9 A in AC-3 utilisation category at voltages up to 440 V, with an AC-1 rating of 20 A for resistive loads. The coil is 100 VAC with a built-in bidirectional peak limiting diode suppressor for transient suppression. Motor power ratings span 2.2 kW at 220–230 VAC up to 4 kW at 480 VAC and 660–690 VAC, all at 50/60 Hz. This makes it suitable for switching three-phase induction motors in the 2–4 kW range across common industrial voltages. The contactor's flame retardance meets V1 per UL 94 and Requirement 2 per NF F 16-101/102, suitable for rail and industrial panel environments where fire safety is specified.
Because this is a discontinued TeSys K contactor, no direct drop-in successor order code is listed. A cross-reference to a current TeSys Deca or TeSys D contactor with equivalent coil voltage and contact rating would need to be evaluated by an integrator for panel fit and aux contact configuration.
