The Schneider Electric LC1G250DCBEEA is a three-pole DC contactor from the TeSys Giga range, built for power switching on DC loads. It carries a DC-1 utilisation category rating, which covers resistive loads like heaters and DC power supplies — not motor starting. The headline rating is 250 A at 40 °C for two poles in series, meaning you get that current-handling when you wire both poles to break the same circuit, doubling the arc-gap. That 1500 V rated insulation voltage (Ui) tells you the contactor is designed to isolate high-voltage DC circuits, typical in battery banks, DC bus distribution, or industrial rectifier outputs. That simplifies wiring and cuts a part from the BOM. Drop-out voltage is between 0.1 and 0.45 times Uc, so it releases cleanly on a low-side signal. Mechanical durability is rated at 1 million cycles, and the contactor is built for vibration and shock: 4 gn closed, 15 gn shock. That makes it a candidate for mobile equipment or industrial machinery with moderate mechanical stress.
This contactor is a plate-mount unit (not DIN-rail), so it bolts to a back panel or mounting plate. The power circuit uses bolted connections or busbars up to 25 x 6 mm, or ring terminals up to 185 mm². Tightening torque is 18 N.m on the power terminals — a torque wrench is the right tool there. The front face carries IP2X protection with shrouds, meaning it resists finger contact but isn't sealed against moisture. That's fine inside a panel; for washdown areas you'd need a separate enclosure. The colour is dark grey.
The LC1G250DCBEEA carries approvals under EN/IEC 60947-4-1, UL 60947-4-1, and CSA C22.2 No 60947-4-2, covering contactors for industrial DC applications. Overvoltage category III means it's rated for fixed-installation distribution-level transients. Protective treatment TH indicates tropicalisation for humid environments.
