Description
About the LC1K
About the LC1K
The Schneider Electric LC1K0610E7 is a compact 3-pole TeSys K contactor rated 6 A AC-3, switching motors up to 2.2 kW at 400 V. It carries a 48 V AC AC coil and a built-in 1NO auxiliary contact, in a 45 mm-wide DIN-rail housing sized for simple motor-control and machine-building panels.

Selection Notes
Where the LC1K0601E7's 1 NC contact is wired for interlocking, the LC1K0610E7's 1 NO contact closes on pickup — the configuration needed for running-indication lamps, a sealing-in (hold) circuit, or feeding a PLC input that confirms the contactor has actually closed. Current rating and coil voltage are unchanged from the 1 NC version: 6 A AC-3 (2.2 kW at 400 V) on a 48 V AC coil.
