The Schneider Electric TeSys Giga LC1G265LSEN is a 3-pole contactor rated for motor switching and general power control. Its headline rating is 265 A in AC-3e utilisation category, which means it is designed for switching three-phase squirrel-cage motors — the 'e' suffix indicates it meets the enhanced electrical endurance profile defined in IEC 60947-4-1. The same contactor also carries AC-1 (resistive load) and AC-4 (plugging/reversing/inching) ratings, so it covers the full duty cycle range from simple on/off to high-stress motor reversals. The control circuit accepts 200...500 V AC 50/60 Hz or 200...500 V DC, with built-in bidirectional peak limiting on the coil — no external varistor or RC snubber required for coil suppression. Closing time is 40...70 ms, opening 15...50 ms.
Mounting is plate-based (not DIN rail), with a 45 mm connection pitch between phases. The power circuit terminates via bolted busbar connections accepting up to 32 x 10 mm bar or ring terminals up to 185 mm². Tightening torque on the power connections is 35 N.m. Front face with shrouds provides IP2X protection per IEC 60529. Mechanical durability is rated at 8 million cycles. The contactor withstands vibration at 4 gn closed and shock at 15 gn closed, making it suitable for installations on machinery subject to moderate mechanical stress.
Sourcing posture
This is a current-production part from the TeSys Giga range. The associated fuse recommendation for short-circuit protection is 315 A aM or 400 A gG, or 450 A UL Type J at 600 V.
