The 100...250 V AC/DC coil with built-in bidirectional peak limiting handles the control voltage common across global plant networks, and the 1 NO + 1 NC auxiliary contact block is integrated on the front face for feedback or interlock wiring without an add-on module. ## What the DC ratings mean for your circuit The 250 A rated operational current is specified at 40 °C ambient for DC-1 (resistive load). For motor or mixed loads you derate to the DC-3 or DC-5 curve — the contactor's real-world limit depends on the load time constant. The rated breaking capacity of 375 A at 1500 V DC (3 poles in series) and 300 A at 1000 V DC (2 poles in series) tells you the contactor can interrupt a fault up to those levels without welding, which is critical for DC circuits where arc extinction is harder than AC. Mounts on a plate (not DIN rail — the 108 mm width and 193 mm depth require a drilled backplate). Power connections are bolted bar or ring lugs up to 185 mm²; the control circuit uses push-in terminals accepting 0.2...2.5 mm² solid or ferruled stranded. Tightening torque is 18 N.m on the power terminals. IP2X with shrouds on the front face meets touch-protection requirements per IEC 60529 and VDE 0106. Certified to EN/IEC 60947-4-1 (contactors and motor-starters), EN/IEC 60947-5-1 (control-circuit devices), UL 60947-4-1, and CSA C22.2 No 60947-4-2. The safety reliability figure B10d = 5,000,000 cycles (mechanical load, per EN/ISO 13849-1) supports use in safety-related control systems up to PL d or e depending on the architecture. Protective treatment TH means the contactor is tropicalised for humid environments.","metaTitle":"TeSys Giga LC1G250DCKUEN Contactor, 250 A DC-1, 1000 V DC","metaDescription":"Schneider Electric TeSys Giga LC1G250DCKUEN DC contactor. 250 A rated operational current (DC-1), 1000 V DC, 3-pole.
