Product details

The LA1KN223M is an auxiliary contact block from the Schneider Electric TeSys K series, designed for front mounting onto contactors or other switching devices. It provides 2 normally-open and 2 normally-closed instantaneous contacts, wired via spring terminals accepting 0.75...1.5 mm² flexible or rigid cable.

Rated insulation voltage (Ui) is 690 V per IEC 60947-5-1, with a 600 V rating under UL and CSA standards. The conventional free-air thermal current (Ith) is 10 A at 50 °C.

Front mounting onto a TeSys K contactor or base, per EN 50012 profile. The spring terminals reduce wiring time compared to screw-clamp; no special tooling needed beyond a ferrule crimper for stranded wire.
