The Schneider Electric LC1G3304EHES207N is a TeSys Giga 4-pole contactor rated for 160 kW at 400 V AC in AC-3e duty — that's the motor-switching rating that governs real-world pump, fan, and conveyor loads. It also carries AC-1 (resistive), AC-4 (plugging/inching), and DC-1/DC-3/DC-5 ratings, so it covers resistive heating banks and DC loads too. Drop-out threshold is 0.1 to 0.45 Uc, so it releases reliably on a sagging control bus.
Plate-mounted, not DIN-rail — the 225 mm depth and 140 mm width need a backplate or sub-panel. Power connections are bolted: bar up to 32 x 10 mm busbar, or lugs up to 185 mm². Tightening torque on the power terminals is 35 N·m — that's substantial; use a torque wrench. Mechanical durability is 8 million cycles. The maximum operating rate is 500 cycles/hour in AC-3/AC-3e duty, 300 in AC-1, 150 in AC-4. For safety circuits, the B10d value is 400,000 cycles at nominal load per EN/ISO 13849-1.
Certified to EN/IEC 60947-4-1 and -5-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, JIS C8201-4-1 and -5-1, plus UL 60335-1 and UL 60335-2-40 Annex JJ for appliance applications. Overvoltage category III. Protective treatment TH (tropicalized).
