Contactor for resistive loads — 45 A AC-1, 220 V AC coil
The Schneider Electric LC1E32008M5WB 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 such as heaters or lighting banks, not motor starting. The coil is 220 V AC 50 Hz, a fixed-frequency wide-range AC control circuit. Screw-clamp terminals on both power and control circuits accept up to 6 mm² flexible with cable end on the power side. Mounts on DIN rail or plate, with a 56 mm width and 93 mm depth footprint that fits standard 4-pole contactor spacing in a panel.
The 45 A AC-1 rating is the continuous resistive current the main poles carry. For motor loads (AC-3), this contactor is not rated. The 220 V AC 50 Hz coil draws 95 VA inrush at cos φ 0.75 and holds with a drop-out threshold of 0.3 to 0.6 Uc. Electrical durability is 350,000 cycles at AC-1; mechanical durability is 8 million cycles. The maximum operating rate is 1,800 cycles per hour at 60 °C, which governs cycling in fast-switching resistive loads like oven zone control. Heat dissipation is 2 to 3 W for the control circuit plus 5 W per pole in AC-1 — total about 23 W at full load, so allow ventilation in a sealed enclosure. IP20 finger protection on the terminals is standard for enclosed panel use.
DIN-rail or plate mount, 56 mm wide. Screw-clamp terminals: power circuit torque to 2.1 N·m, control circuit to 1.2 N·m. Wire range on power side is 1 to 6 mm² flexible with cable end. Operating altitude is 3,000 m without derating. Protective treatment TH per IEC 60068-2-30 means it withstands humid, tropical environments — relevant for HVAC or outdoor cabinet installations.
