The Schneider Electric TeSys K LC1K06016SLS207 is a 3-pole contactor rated for AC-3, AC-3e, and AC-4 duty at 6 A up to 440 V, making it a direct fit for switching small motor loads in control panels. The 72 V DC coil with integral suppression draws 1.8 W hold-in power at 20 °C, so it's sized for low-energy control circuits where a standard 24 V or 110 V coil won't match the bus voltage. The built-in suppression means you don't need an external flyback diode or RC snubber across the coil — one less component to source and mount.
The AC-3 rating at 6 A governs motor switching up to that current — the rating that matters for a BOM line driving a fractional-horsepower pump, fan, or conveyor. Electrical durability is 1.3 million cycles at 6 A AC-3, so it's not a one-shot part; it holds up in cyclic duty. Mechanical durability is 30 million cycles, which outlasts the electrical life in most applications. Minimum switching is 5 mA at 17 V for the signalling circuit, meaning it can handle low-level PLC inputs without contact wetting issues. That's a real advantage when the aux contact feeds a 24 V DC digital input card — no false opens from oxide film. The 57 mm depth, 45 mm width, and 58 mm height fit the standard TeSys K footprint, so it drops into an existing DIN-rail or plate-mounted layout without re-spacing.
The contactor carries 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 approvals — so it's accepted in North American, European, Chinese, and Japanese installations without a separate UL/CSA variant. Flame retardance is V0 per UL 94, which satisfies the panel flammability requirements for most industrial control enclosures.
Deployment context
The lugs-ring terminals accept ring tongues with a 7 mm outer diameter, torqued to 0.8–1.3 N·m using a 3.2 mm flat or Philips No 2 screwdriver — no special tooling needed.
