Motor power and coil fit
The Schneider Electric LC1G115LSEN is a 3-pole contactor from the TeSys Giga range, built for switching motor loads up to 75 kW at 690 V AC-3e and 55 kW at 400 V AC-3. The same frame covers AC-4 duty at slightly reduced power, e.g., 55 kW at 400 V AC-4. At 460/480 V 60 Hz, it delivers 75 hp. The coil accepts any control voltage between 200-500 V AC or DC, simplifying panel integration across plants with mixed control supplies.
Durability and thermal load
Mechanical durability is rated at 8 Mcycles, well above typical contactors in this frame size, making it suitable for high-cycle applications like conveyors, pumps, and compressors. Power dissipation per pole reaches 10 W in AC-1 at 250 A and 3 W in AC-3 at 115 A; factor these into panel thermal calculations, especially in enclosed cabinets.
Mounting and termination
Power circuit accepts busbar 25 x 6 mm or lugs 185 mm²; torque to 18 N.m (159.3 lbf.in). Control circuit uses push-in terminals for 0.2–2.5 mm²; front face achieves IP2X.
