DC contactor for resistive loads
The LC1E100ADCH1S260N is a 1-pole DC contactor from Schneider Electric's Easy TeSys Control range, designed for resistive load switching. Its conventional free-air thermal current (Ith) is 100 A for the power circuit, making it a fit for DC circuits where the load is primarily resistive — heaters, DC power supplies, or ballast loads. The control circuit runs on 12 V DC with a hold-in power consumption of 5.5 W, and the coil acceptance range is 0.85 to 1.1 times Uc for pick-up, dropping out between 0.1 and 0.75 Uc. That 12 V DC coil is common in battery-backed control panels or low-voltage DC bus systems.
Switching envelope and duty cycle
Maximum switching voltage is 1000 V DC, with a minimum switching current of 0.1 A and minimum switching voltage of 8 V DC. That low minimum means it can reliably switch small signal-level loads — useful when the contactor doubles as a disconnect for a control transformer or a small DC fan circuit. Operating time is 50 ms on closing and 30 ms on opening, which is typical for a DC contactor of this size — fast enough for most load-break applications but not intended for high-speed chopping. Electrical durability is specified at 1000 cycles for breaking 100 A at 750 V DC and 1000 cycles for breaking 100 A at 1000 V DC, each with a 0.6-second open time and 5.4-second break interval. That's a limited-life application — plan for replacement intervals if the contactor sees frequent full-load breaks.
Mounting and environmental fit
Dimensions are 2.1 in (54.6 mm) depth, 1.4 in (35.5 mm) width, and 2.8 in (70.1 mm) height — a compact 1-pole footprint that fits standard DIN-rail or panel-mount layouts. Mounting support is vertical, and the power circuit terminals accept M5 nuts with flat and spring washers; tightening torque is 31.0 to 39.8 lbf·in (3.5 to 4.5 N·m). IP60 protection means it's dust-tight but not sealed against moisture — suitable for indoor panel installation where washdown or condensation isn't a concern. Operating temperature range is -40 to 185 °F (-40 to 85 °C), and it operates without derating up to 4000 m altitude.
Standards and compliance
Designed to IEC 60947-4-1 and GB/T 14048.4, the standard for contactors and motor-starters. Rated insulation voltage (Ui) is 1000 V for the power circuit, with an impulse withstand voltage (Uimp) of 6 kV when the coil is not connected to the power circuit. Insulation resistance is 1000 MΩ at 1000 V DC, and the contactor handles mechanical robustness of 5 g vibration (10 to 500 Hz) and 20 g shock for 11 ms.
