The Schneider Electric Easy TeSys LC1E18008N5WB is a 4-pole contactor rated for 32 A in AC-1 utilisation category at ≤440 V, meaning it is designed for switching resistive loads such as heaters or lighting banks where inrush is minimal. The 415 V AC 50 Hz wide-range coil pulls 95 VA inrush at cos φ 0.75 and holds with 2–3 W dissipation. With 2 NO + 2 NC main poles and no built-in auxiliary contacts, it fits applications where the load circuit needs isolation across four poles and external auxiliaries are added separately.
For motor loads (AC-3), this part is not rated — it is a resistive-load specialist. Breaking capacity of 144 A at 440 V and making capacity of 180 A at 440 V ensure it can close into and interrupt fault currents within its coordination type 1 limit, backed by a 35 A gG fuse at ≤690 V. Mechanical durability of 10 million cycles and electrical durability of 300,000 cycles at AC-1 mean this contactor outlasts many panel designs in resistive switching duty. Maximum operating rate of 1800 cycles per hour at 60 °C suits cyclic heater control. Operating time of 12–22 ms closing and 4–19 ms opening is fast enough for most resistive load sequencing.
Mounts on DIN rail or plate. The 45 mm width matches standard 4-pole contactor footprints — one 17.5 mm module per pole plus a sliver. Depth of 80 mm and height of 74 mm leave room for wiring ducts and adjacent devices. Screw clamp terminals accept up to 6 mm² solid or 4 mm² flexible with ferrule on the power circuit; control circuit terminals take 1–4 mm². Tightening torque is 1.2 N·m for both power and control circuits — a common value that avoids over-torquing smaller terminals. The TH protective treatment per IEC 60068-2-30 adds damp-heat resistance for tropical or non-conditioned environments.
Overvoltage category III suits fixed-installation distribution boards. Fire resistance of 850 °C per IEC 60695-2-1 means the enclosure material self-extinguishes.
