The Schneider Electric LC1E32004M5WB is a 4-pole contactor from the Easy TeSys Control range, rated 45 A in AC-1 utilisation category at ≤ 440 V — meaning it is sized for resistive loads like heaters or lighting banks, not motor starting. The coil is 220 VAC 50 Hz, a fixed-frequency wide-range type; dropout occurs between 30% and 60% of rated voltage, operational pickup between 70% and 125%. Mounts on either a DIN rail or a plate, with screw-clamp terminals accepting up to 6 mm² on the power circuit and 4 mm² on the control circuit. The IP20 finger-safe enclosure suits panel-mount installation where the contactor is behind a cabinet door.
The headline rating is 45 A at ≤ 440 V in AC-1 (resistive load). For a panel-builder or MRO planner, this is the number that governs the main power path: the contactor can switch resistive loads continuously at that current without exceeding the thermal limit. The power circuit impedance is 2.5 mΩ at 50 Hz, and each pole dissipates 5 W in AC-1 duty — useful for calculating enclosure heat rise. Rated breaking capacity is 256 A at 440 V, and making capacity is 320 A at 440 V — both per IEC 60947. The associated fuse recommendation is 63 A gG at ≤ 690 V, coordination type 1. Mechanical durability is 8 million cycles; electrical durability in AC-1 is 350,000 cycles. For a line that cycles infrequently (e.g., a heater bank switching a few times per hour), that electrical life translates to decades of service. Maximum operating rate is 1800 cycles per hour at 60 °C. The TH protective treatment (IEC 60068-2-30) adds resistance to humid, cyclic conditions.
The 850 °C glow-wire test per IEC 60695-2-1 is passed, confirming fire resistance for the enclosure material.
