The Schneider Electric TeSys K LC1K1210K7 is a 3-pole contactor rated 12 A in AC-3 duty at 440 V, meaning it switches three-phase motor loads up to that current under full load. The AC-3e rating aligns with energy-efficiency motor standards. It also carries AC-1 (resistive) and AC-4 (inching/plugging) utilization categories, with electrical durability figures of 1.3 million cycles at 12 A AC-3, 300,000 cycles at 20 A AC-1, and 20,000 cycles at 72 A AC-4. Mechanical endurance is 10 million cycles.
Inrush power is 30 VA, holding at 4.5 VA. Operating voltage limits are 0.8...1.15 Uc, dropout at ≥0.20 Uc. Coil energization and de-energization times are 10...20 ms for NO opening and closing. The control circuit can handle up to 400 Hz signalling frequency.
Mounts on DIN rail or plate. Screw clamp terminals accept one or two conductors: solid 1.5...4 mm², flexible without ferrule 0.75...4 mm², or flexible with ferrule 0.34...2.5 mm². Tightening torque is 0.8...1.3 N·m. IP2X finger protection per VDE 0106.
Certified to EN/IEC 60947-4-1, GB/T 14048.4, UL 60947-4-1, CSA C22.2 No 60947-4-1, and JIS C8201-4-1. 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. Safety reliability B10d is 1,369,863 cycles at nominal load and 20,000,000 cycles at mechanical load per EN/ISO 13849-1.
