The Schneider Electric LC1E12004M5WB is a 4-pole contactor from the Easy TeSys Control range, rated for 25 A in AC-1 utilisation category at ≤ 440 V AC — meaning it is sized for resistive loads such as heaters or lighting banks, not motor starting. The 4 NO pole composition gives you four normally-open main contacts, all switching the same phase or load group. The coil is 220 V AC at 50 Hz, wide-range control circuit type, with a drop-out threshold of 0.3–0.6 Uc and pick-up of 0.7–1.25 Uc across -5 to 55 °C. Inrush power is 95 VA at 50 Hz cos φ 0.75; steady-state heat dissipation runs 2–3 W on the control side.
The 45 mm wide footprint and 74 mm height fit standard 4-pole contactor slots in distribution boards or control enclosures. Depth is 80 mm, so allow clearance for wiring and the screw clamp terminals. Screw clamp terminals accept 1–4 mm² flexible with cable end or solid on the power circuit, and 1–2.5 mm² on the control circuit. Tightening torque is 1.2 N·m for both power and control terminals. IP20 finger-safe protection means it is suitable for enclosed panels where operators do not contact live parts.
Electrical performance and durability
Rated insulation voltage is 690 V, with a rated breaking capacity of 96 A at 440 V and a making capacity of 120 A at 440 V AC per IEC 60947-4-1. Electrical durability is 300,000 cycles under AC-1 load; mechanical durability is 10 million cycles. Maximum operating rate is 1,800 cycles per hour at 60 °C. Associated fuse rating is 25 A gG at ≤ 690 V, coordination type 1. The contactor withstands vibration of 3 Gn closed and shock of 10 Gn closed, making it mechanically robust for industrial environments.
