The Schneider Electric LC1E25008M5WBIN is a 4-pole contactor from the Easy TeSys Control range, rated for 50 A at ≤415 V AC in AC-1 utilisation category — meaning it's sized for resistive loads like heaters or lighting banks, not motor starting. The 220 V AC 50 Hz coil is wide-range, holding in at 0.7–1.25 Uc and dropping out at 0.3–0.6 Uc across -5 to 55 °C. Pole configuration is 2 NO + 2 NO (four poles total), with no auxiliary contact block fitted — you'll add one if you need feedback to a PLC or status indication on the panel door.
The headline 50 A AC-1 rating is the continuous resistive current at ≤40 °C — that's the number that governs your bus bar and cable sizing for a heater or transformer load. Don't confuse it with an AC-3 motor rating; this contactor is listed for resistive duty only per the utilisation category. Breaking capacity is 200 A at 440 V, making capacity 250 A at 440 V, so it handles inrush from cold resistive elements without welding. Mechanical durability of 10 million cycles and electrical durability of 350,000 cycles at AC-1 tell you it's built for frequent switching in a process line, not a once-a-day HVAC contactor.
Mounting, wiring, and panel integration
Power circuit terminals accept up to 10 mm² flexible with cable end, control circuit up to 4 mm². Tightening torque is 1.5 N·m on power, 1.2 N·m on control — use a torque screwdriver; overtightening strips the screw clamp on these smaller terminals.
