The Schneider Electric TeSys Giga LC1G115EHES207N is a 3-pole contactor rated for 55 kW at 400 V AC in AC-3e duty — the utilisation category for standard squirrel-cage motor switching, including occasional inching and plugging. That 55 kW figure at 400 V is the one that governs the motor load it handles; the same contactor carries higher kW ratings at higher voltages (75 kW at 690 V AC-3e), so the 400 V line voltage is the binding constraint for most European and Asian panels. The control circuit accepts 48 to 130 V AC or DC, with a built-in bidirectional peak-limiting coil that suppresses transients without an external varistor or RC snubber — a detail that saves panel space and simplifies BOM planning.
Deployment context
This contactor mounts to a plate (not a DIN rail), so it integrates into a panel via bolted connection. The power circuit accepts bar or lug-ring terminals up to 185 mm²; the control circuit uses push-in terminals accepting 0.2 to 2.5 mm² solid or stranded wire. The 35 mm connection pitch aligns with standard busbar systems. The IP2X front face with shrouds meets IEC 60529 for finger-safe installation — a requirement for panels that must remain accessible during maintenance without full lockout.
The LC1G115EHES207N carries approvals under EN/IEC 60947-4-1 and EN/IEC 60947-5-1 for contactors and control-circuit devices, plus UL 60947-4-1 and CSA C22.2 No 60947-4-1 for North American installations. It also complies with JIS C8201-4-1 and JIS C8201-5-1 for Japanese markets, and with IEC 60335-1 Clause 30.2 and UL 60335-1 for appliance applications — meaning it can be specified into equipment that must pass glow-wire and hot-wire ignition tests.
