Mechanical durability is 8 Mcycles, and the maximum operating rate hits 600 cycles/h in AC-3. Coil power consumption shows an inrush of 215 W DC, but the built-in bidirectional peak limiting keeps the hold-in draw lower. Drop-out threshold is 0.1 to 0.45 Uc (at <60 °C), which is wide enough to avoid nuisance drop on moderate sags. Mounts on a plate; dimensions: 255 mm high, 193 mm deep, 143 mm wide. Power terminals accept bar or bolted lugs up to 185 mm². Control circuit uses push-in terminals for 0.2…2.5 mm² stranded or solid. Tightening torque for main connections: 18 N·m.","metaTitle":"Schneider LC1G1854LSEA TeSys Giga, 4P 185A AC-3","metaDescription":"LC1G1854LSEA active TeSys Giga 4-pole contactor from Schneider.
