Rated insulation voltage is 1000 V, and it handles utilisation categories AC-3, AC-3e, AC-1, AC-5a, AC-5b, AC-6a, AC-6b, DC-1, DC-3, and DC-5 — meaning it switches motor loads, resistive heaters, and DC circuits across a wide industrial range. Safety reliability is documented with B10d values of 400,000 cycles at nominal load and 3,000,000 cycles at mechanical load per EN/ISO 13849-1. Power dissipation per pole is 20 W in AC-1 at Ith 305 A and 6 W in AC-3 at Ith 185 A — this drives the thermal budget inside the enclosure; the 0.00017 Ohm average impedance confirms low resistive losses at rated current. Associated fuse ratings are listed for multiple standards: 200 A aM, 160 A aM, 315 A gG, and 300 A UL Type J at ≤600 V — giving the panel builder a direct guide for short-circuit protection coordination without derating guesswork. ## Mounting and integration details Mounting is plate-based (not direct DIN rail), with a connection pitch of 35 mm. The power circuit accepts bar or busbar cross-section up to 25 x 6 mm, or ring terminals up to 185 mm². Tightening torque for power connections is 159.3 lbf·in (18 N·m). The depth is 7.6 in (193 mm), width 5.6 in (143 mm), and height 7.6 in (193 mm) — dimensions that matter when planning gland plate clearance and fill factor in a multi-contactor lineup. IP degree of protection is IP2X on the front face with shrouds per IEC 60529 and VDE 0106, meaning finger-safe but not sealed against moisture — suitable for indoor panel installation with proper enclosure.","metaTitle":"Schneider Electric LC1G1854LSEN TeSys Giga Contactor, 4P","metaDescription":"Schneider Electric LC1G1854LSEN TeSys Giga contactor, 4 NO poles, 200-500 V AC/DC coil.
