Schneider Electric LC1DGKM7 TeSys Deca Capacitor Duty Contactor 3P 16.7 kvar 400 V 220 V AC Coil Contactor

The Schneider Electric LC1DGKM7 is a 3-pole TeSys Deca capacitor-duty contactor rated 16.7 kvar at 400 V (28.5 kvar at 690 V) for switching three-phase power-factor-correction capacitor banks. It runs on a 220 V AC 50/60 Hz coil, includes 1 NO + 2 NC instantaneous auxiliary contacts with front-mounted early-make poles and pre-wired damping resistors, and mounts on a 45 mm wide DIN rail or plate.

Selection Notes

Pre-wired damping resistors on the early-make poles limit inrush current when switching capacitor banks — a feature a plain LC1D motor contactor lacks, so it should not be substituted for power-factor-correction duty. The 240 cyc/h operating-rate ceiling is set by the damping-resistor thermal limit rather than contact life, which bounds how often an automatic PFC regulator can step this stage. Choose a higher-kvar variant in the same family if the capacitor bank step exceeds 16.7 kvar at 400 V.
