The 20 A AC-1 rating covers resistive loads. Utilisation categories AC-1, AC-3, and AC-4 are all covered, so it handles both general switching and inching/jogging duty. Three normally-open main poles, one normally-open auxiliary contact built in. Coil is 230-240 V AC, 50/60 Hz. Heat dissipation is 1.3 W — negligible in a crowded panel but worth noting for thermal coordination. Withstands 115 A for 1 second on the power circuit — enough to ride through a short-duration fault without welding contacts. The signalling circuit holds 110 A for 100 ms.","metaTitle":"Schneider LC1K12105U7 TeSys K Contactor, 3P, 12 A AC-3, 230-","metaDescription":"Active-production TeSys K contactor, 3P, 12 A AC-3 at 440 V, 1 NO aux, 230-240 V AC coil.
