The LC1K1210FC72 is a TeSys K three-pole contactor with a 36 V AC coil and one normally open auxiliary contact.
Motor power coverage across common voltages
Motor power ratings: 3 kW at 220–230 V AC, 5.5 kW at 380–415 V and 440 V, and 4 kW at 480 V, 500–600 V, and 660–690 V. Covers 50/60 Hz supplies.
Coil suppression built in — no external diode needed
The coil includes a built-in bidirectional peak-limiting diode suppressor. No external flyback diode or RC snubber needed across the coil terminals.
Thermal and mechanical fit
Heat dissipation is 1.3 W — low enough that you can pack it in a control cabinet without worrying about derating adjacent components. The flame-retardant housing carries a UL 94 V1 rating and meets NF F 16-101/102 requirements, which matters for rail and transit applications.
