The Schneider TeSys K LC1K1610K72 is a three-pole contactor rated for motor control in AC-3 duty up to 16 A at 440 V. That AC-3 rating means it's built for starting and stopping squirrel-cage induction motors — the standard load type on conveyors, pumps, and fans — where the contacts make and break the motor's locked-rotor current. The 100 V AC coil pulls in at 30 VA inrush and holds at 4.5 VA, with a dropout threshold above 20% of nominal control voltage, so it's compatible with standard 100 V control transformers without additional suppression.
This contactor mounts on either a DIN rail or a plate, with a 45 mm width footprint — that's a single 45 mm module, so it slots into a standard enclosure without eating up rail space. The screw-clamp terminals accept up to 4 mm² solid or 2.5 mm² flexible with ferrules, and the tightening torque range of 0.8 to 1.3 N.m is typical for this class. Depth is 57 mm, height 58 mm — compact enough for shallow back panels.
Electrical durability is 1.3 million cycles at that rating, so it's sized for moderate-duty cycling. The built-in coil suppression (integral suppression device) means you don't need an external RC snubber across the coil for most PLC outputs, but verify the free-wheel diode polarity if the control circuit is DC-switched. Minimum switching capability is 5 mA at 17 V for the signalling circuit, which covers dry-contact feedback to a PLC input.
