The LC1K0910P7S335 is a three-pole TeSys K contactor from Schneider Electric, rated for AC-3 motor control at 9 A and 440 V, with a 230 V AC coil and one normally open auxiliary contact. It also carries an AC-1 resistive load rating of 20 A. The 45 mm wide body and 57 mm depth fit standard DIN-rail enclosures.
The AC-1 rating of 20 A covers resistive loads like heaters, where switching is less stressful. The 230 V AC coil pulls in reliably across the standard line voltage; coil dropout typically occurs below about 0.8× nominal.
TeSys K contactors are compact motor starters and load switches for control panels in industrial machinery, conveyors, pumps, and HVAC equipment. The 3-pole configuration with one auxiliary contact suits simple motor start/stop circuits or resistive load switching in a DIN-rail mounted panel.
