The LC1G250DCEHEN: The 250 A DC-1 rating governs resistive loads; for motor or inductive DC loads you'd need to check the DC-3/DC-5 curves, which aren't listed here. The 1000 V DC maximum with two poles in series means this contactor handles high-voltage DC bus applications common in solar, battery storage, or traction systems. The 48-130 V AC/DC control voltage covers standard 48 V, 110 V, and 120 V control supplies — verify your panel's control voltage falls within the 0.8 to 1.1 times Uc operational limits. The B10d safety reliability level of 5 million cycles (per EN/ISO 13849-1) supports use in safety circuits where the contactor is mechanically loaded — relevant for emergency-stop or guard-door applications.
Standards and compliance for the panel builder
Certified to EN/IEC 60947-4-1, EN/IEC 60947-5-1, UL 60947-4-1, and CSA C22.2 No 60947-4-2. The overvoltage category is III, suitable for fixed-installation distribution panels. IP2X front-face protection with shrouds (per IEC 60529 and VDE 0106) means fingers are protected from live parts once the shrouds are fitted — standard for open-panel mounting on a plate.
Mounting and wiring notes for the wireman
Mounts on a plate (not DIN rail) with a 35 mm connection pitch. Power circuit connections accept busbars up to 25 x 6 mm, lugs/ring terminals up to 185 mm², or bolted connection. Control circuit uses push-in terminals for 0.2-2.5 mm² solid/stranded or 0.25-2.5 mm² flexible with ferrules. Tightening torque is 18 N.m on the power terminals.
