The LC1K16105M72 is a TeSys K three-pole contactor rated 16 A in AC-3 duty at 440 V, with a 220-230 V AC coil. The coil has a built-in bidirectional peak limiting diode suppressor, so you don't need to add an external snubber across the coil terminals.
Motor Power and Ratings
This contactor handles motor power up to 7.5 kW at 380-415 VAC, and 4 kW at 480 VAC or 500-690 VAC. That's the AC-3 rating — the one that matters for motor switching. The AC-1 rating (resistive loads) is higher but not listed separately; the 16 A figure is the AC-3 operational current. Short-time withstand current is 115 A for 1 second on the power circuit, enough for brief overloads during starting.
Physical and Compliance
The housing is rated V-1 per UL 94 for flame retardance. Heat dissipation is 1.3 W at rated load, so no special ventilation is needed in a typical enclosure.
