Integrator note – LC1G1154LSEA
The Schneider LC1G1154LSEA TeSys Giga is a 4-pole power contactor with a built-in bidirectional peak limiting coil accepting 200...500 V AC at 50/60 Hz or 200...500 V DC. It covers utilisation categories AC-3, AC-3e, AC-1, AC-5a/b, AC-6a/b, DC-1, DC-3, and DC-5 – meaning it handles motor switching, resistive loads, and DC circuits. Rated making capacity is 1560 A at 440 V; breaking capacity is 1040 A at the same voltage. Mechanical durability hits 8 million cycles, so it suits high-duty applications like conveyor lines or compressor banks.
Mounting & connections – panel layout
Mounts on a plate with a connection pitch of 35 mm (1.4 in). Power circuit terminals accept bar (max 25 x 6 mm), lugs/ring terminals up to 185 mm², or bolted connection. Control circuit uses push-in terminals: 0.2…2.5 mm² solid/stranded, 0.25…2.5 mm² with ferrules. Tightening torque for main connections is 18 N·m (159.3 lbf·in). IP2X front protection when shrouds are fitted. Power dissipation per pole runs 10 W at AC-1 (Ith 250 A) and 3 W at AC-3 (Ith 115 A). Auxiliary contacts: 1 NO + 1 NC built in.
