It provides a means of extending the control circuit switching capacity of the host device, carrying a conventional free-air thermal current (Ith) of 10 A at 50 °C and a rated insulation voltage (Ui) of 690 V per IEC 60947-5-1, with equivalent 600 V ratings under UL and CSA standards. ## Electrical Ratings and Compliance Rated operational voltage (Ue) is 690 V AC at 25 to 400 Hz, and the block carries a making capacity of 110 A at 10 MOhm, which governs its ability to close onto a fault or heavy inrush without welding the contacts. Insulation coordination is verified to IEC 60947-5-1 at 690 V, with parallel UL and CSA certifications at 600 V — a compliance triad that satisfies most panel builder and site electrical engineer requirements for control circuit isolation. Spring-cage terminals accept one cable of 0.75 to 1.5 mm², either flexible without ferrule or rigid, per the specification. The front-mounting location on the TeSys K contactor base means the block clips on without additional DIN-rail space, preserving panel fill factor.","metaTitle":"Schneider Electric LA1KN023M TeSys K Auxiliary Contact Block","metaDescription":"Obsolete TeSys K auxiliary contact block, 2NC, front mount, spring terminals.
