The built-in bidirectional peak-limiting diode suppressor handles coil transients without external snubbing. ## Motor power coverage This contactor switches motor loads up to 5.5 kW at 380–415 V AC 50/60 Hz, 4 kW at 480 V and 500–600 V, and 3 kW at 220–230 V. The 660–690 V rating also carries 4 kW. Heat dissipation is 1.3 W, so no special ventilation is required in a typical control panel.","metaTitle":"Schneider TeSys K LC1K12107D72 Contactor, 12 A AC-3, 42 V Co","metaDescription":"Obsolete TeSys K contactor, 3P, AC-3 12 A at ≤440 V, 42 V AC coil, 1 NO aux.
