Schneider LC1G1854EHEA is a TeSys Giga 4-pole contactor with a 48–130 V AC/DC control circuit coil and a built-in bidirectional peak limiting coil technology. Rated insulation voltage is 1000 V. It is designed for power switching across a broad set of utilisation categories including AC-3, AC-3e, AC-1, DC-1, DC-3, and DC-5. Mechanical durability is rated at 8 million cycles, and the contactor carries IEC/EN 60947, UL 60947-4-1, and CSA C22.2 No 60947-4-1 listings. The dark grey body measures 255 mm high, 143 mm wide, and 193 mm deep with a 35 mm pole pitch — sized for plate mounting.
Motor ratings and thermal design
The contactor is rated at 50 hp at 200/208 V, 60 hp at 230/240 V, 125 hp at 460/480 V, and 150 hp at 575/600 V 60 Hz. Power dissipation is 20 W per pole under AC-1 at 305 A, and 6 W per pole under AC-3 at 185 A – the AC-3 dissipation figure drives enclosure sizing for typical motor duty. Initial inrush power on the DC coil is 190 W. Maximum operating rate is 600 cycles/hour for AC-3 and AC-3e, dropping to 300 cycles/hour for AC-1. These constraints matter for rapid cycling applications like conveyors or compressors.
Standards documentation includes EN/IEC 60947-4-1, EN/IEC 60947-5-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, JIS C8201-4-1, JIS C8201-5-1, UL 60335-1, and UL 60335-2-40 Annex JJ. RoHS/REACH declarations are typically provided with the shipment upon request.
Connection and mounting details
Power circuit terminals accept busbars up to 25×6 mm, ring lugs for 185 mm² cable, or bolted connections. Control circuit terminals use push-in technology for 0.2–2.5 mm² solid/stranded or 0.25–2.5 mm² flexible with ferrules. Tightening torque for power terminals is 18 N·m. The front face achieves IP2X with shrouds. Mechanical robustness is specified for vibrations up to 4 gn when closed and shocks up to 15 gn when closed – suitable for industrial panels subject to mild machine vibration.
