One normally-closed (NC) auxiliary contact is included on the front, rated for signalling circuits down to 5 mA and 17 V. That low-level switching capability means it can be wired directly into a PLC input without a separate interface relay. Panel builders will appreciate the screw-clamp terminals that accept one or two conductors: solid up to 4 mm², flexible with ferrule up to 2.5 mm². The 1.3 W heat dissipation means it won't cook adjacent components in a crowded enclosure. Rated for operation up to 2000 m without derating, and the coil holds in from 0.8 to 1.15 Uc, dropping out at 0.2 Uc. That's a wide enough margin to ride through brownouts on a marginal line supply. The contactor carries a full suite of global approvals: EN/IEC 60947-4-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, JIS C8201-4-1, and GB/T 14048.4. It also meets IEC 60335-1 Clause 30.2 and IEC 60335-2-40 Annex JJ for appliance applications. Flame retardance is V1 per UL 94.","metaTitle":"Schneider TeSys K LC1K1201K72 Contactor, 3P, 12A AC-3, 1NC A","metaDescription":"Active-production TeSys K contactor, 3-pole, 12 A AC-3/AC-3e at 440 V, 1 NC auxiliary contact, 100 V AC coil with integral suppression.
