The Schneider Electric LC1G2254EHES207N is a 4-pole power contactor from the TeSys Giga range, rated for motor control and power switching across AC-1 through AC-6b and DC-1 through DC-5 utilisation categories. Its headline motor rating is 110 kW at 400 V AC-3e, with the same figure at 415 V and stepping up to 160 kW at 690 V AC-3e. The control circuit accepts 48 to 130 V AC or DC, with built-in bidirectional peak limiting on the coil. That coil technology means you don't need external suppression on the control side — the contactor handles its own inrush (445 W peak) and holds in with low dissipation.
At 400 V, 110 kW translates to roughly 225 A continuous in AC-3e duty, and the contactor's power dissipation per pole is 8 W at that current. The mechanical durability of 8 million cycles is high for this frame size, and the maximum operating rate of 500 cycles per hour in AC-3e matches a fast cycling conveyor or pump station. The 4-pole configuration (3 NO main poles + 1 NO + 1 NC auxiliary built in) gives you the third pole for a star-delta transition or for switching a second load, and the auxiliary set covers feedback to the PLC without an add-on block.
This contactor mounts to a plate, not a DIN rail — the 105 mm width and 193 mm depth mean it takes up a dedicated footprint in the enclosure. The power connections are bolted: bar or busbar up to 25 x 6 mm, or ring lugs up to 185 mm². The tightening torque on the main terminals is 18 N·m, so a torque wrench is part of the install. The front face with shrouds gives IP2X finger protection per IEC 60529. The protective treatment (TH) means it's coated for tropical humidity — relevant if the panel sits in an unconditioned space.
