The LC1G6304LSEN is a 4-pole TeSys Giga contactor rated for 630 A in AC-3 duty, with a 200-500 V AC/DC coil. The coil uses built-in bidirectional peak limiting, so you don't need external suppression. Rated insulation voltage is 1000 V, and the contactor carries a making capacity of 7220 A at 440 V and a breaking capacity of 5550 A at 440 V — that's the short-circuit capability when coordinating with upstream protection.
The utilisation categories cover AC-3, AC-3e, AC-1, AC-5a, AC-5b, AC-6a, AC-6b, DC-1, DC-3, and DC-5. For resistive loads (AC-1), the thermal current Ith is 1050 A per pole. The contactor is rated for vibrations up to 4 gn when closed and shocks up to 15 gn — figures that matter on conveyors or mobile equipment. Power circuit terminals accept busbars up to 52 x 20 mm or ring lugs up to 185 mm². Control circuit uses push-in terminals for 0.2-2.5 mm² wire. The connection pitch is 70 mm, and tightening torque is 58 N·m on the power terminals.
Safety reliability data is available: B10d = 100,000 cycles at nominal load and 1,800,000 cycles at mechanical load per EN/ISO 13849-1. The auxiliary contact block is 1 NO + 1 NC built-in.
