FAQ

The LA1KN11 auxiliary contact block is designed for front mounting on TeSys K contactors and control relays, including models such as LC1K, LP1K, CA2K, CA3K, and CA4K.

The terminals use screw clamp connections. They accept one 1.5 to 4 mm squared solid or stranded cable without a cable end, or two 1.5 to 2.5 mm squared cables. The recommended tightening torque is 1.3 N.m.

1NO stands for one 'Normally Open' contact, which is open when the contactor is de-energized and closes when energized. 1NC stands for one 'Normally Closed' contact, which is closed when the contactor is de-energized and opens when energized. This allows for auxiliary logic and signaling functions.
