The Schneider Electric TeSys Giga LC1G150LSEN is a 3-pole contactor rated for motor switching up to 75 kW at 400 V AC in both AC-3 and AC-3e duty classes — the e-suffix means it's tested to the enhanced electrical endurance profile for IEC contactors. At 460/480 V 60 Hz it carries a 100 hp rating, so it fits North American motor schedules as well. The coil accepts 200...500 V AC or DC, which simplifies panel wiring when the control voltage is shared across a mixed AC/DC bus.
AC-3e at 75 kW / 400 V is the headline motor-switching rating — it handles the starting inrush and breaking of a squirrel-cage motor under normal duty. The same contactor also lists AC-4 at 75 kW / 400 V, which covers plugging and inching where the contactor opens under full locked-rotor current. That dual rating means this part can serve both standard start/stop and reversing or jogging applications without oversizing. The average impedance per pole is 0.00018 ohm, which keeps voltage drop low under full load. For high-speed cycling applications like indexing conveyors, that rate is the practical ceiling.
The LC1G150LSEN is a panel-mount contactor — plate-mount support, with a connection pitch of 35 mm between phases. Power terminals accept bar or busbar up to 25 x 6 mm, or lugs up to 185 mm². Tightening torque for the power connections is 18 N.m. Front face with shrouds carries IP2X protection per IEC 60529 and VDE 0106 — finger-safe against accidental contact. The TH protective treatment means it's coated for tropical/humid environments, which matters for unheated enclosures or washdown areas.
This contactor carries compliance with EN/IEC 60947-4-1 and EN/IEC 60947-5-1 (the main contactor and aux contact standards), plus UL 60947-4-1 and CSA C22.2 No 60947-4-1 for North American acceptance. It also meets JIS C8201-4-1 and JIS C8201-5-1 for Japanese installations, and the IEC 60335 series for appliance applications.
