FAQ

Which contactors is the LA1KN11 compatible with?

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.

What are the terminal screw specifications for this block?

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.

What do the 1NO and 1NC designations mean?

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.
