The Schneider Electric TeSys K LC1K06016BLS207 is a 3-pole contactor rated for AC-3 duty at 6 A at up to 440 V — that is the motor-switching current, not the resistive load. The AC-3 utilisation category means it handles starting and plugging of squirrel-cage motors, where the inrush can be 5–7 times the rated current. The 6 A AC-3 figure governs the motor it can switch; for a typical 400 V three-phase induction motor, this covers about 2.2 kW. The 24 VDC coil is a low-consumption type drawing 1.8 W holding power with integral suppression built in, so no external flyback diode is needed on the control circuit. Coil voltage tolerance is wide: it operates from 0.7 to 1.3 times the rated control voltage (Uc) and drops out reliably at 0.1 Uc below 50 °C. That gives you about 16.8 V to 31.2 V operating range on a nominal 24 VDC supply, with dropout below 2.4 V — useful for brownout ride-through or long cable runs where voltage drop matters. The 1 NC auxiliary contact is instantaneous type, rated for signalling circuits down to 5 mA at 17 V minimum. That low-level switching capability means it works with PLC digital inputs and safety relays without needing a separate interface relay.
Mounts on DIN rail or plate via the rail/plate support. The 45 mm width (3 module spaces) and 57 mm depth keep it compact for dense control panels. Power circuit connections use ring lugs with a 7 mm outer diameter, torqued to 0.8–1.3 N·m using a 3.2 mm flat or Phillips No. 2 screwdriver. The operating time — 10–20 ms to open NO contacts on coil de-energisation, 30–40 ms to close on energisation — is relevant for sequencing logic and safety circuit timing. Rated for 3600 cycles per hour maximum operating rate, with mechanical durability of 30 million cycles. Electrical durability is 1.3 million cycles at 6 A AC-3 at up to 440 V — that is the practical life under motor load.
Certified to EN/IEC 60947-4-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, GB/T 14048.4, and JIS C8201-4-1 — so it is accepted across European, North American, Chinese, and Japanese installations. Flame retardance is V0 per UL 94.
