The Schneider Electric LC1E18008M5WB is a 4-pole contactor from the Easy TeSys Control range, rated for resistive load switching (utilisation category AC-1) at 32 A up to 440 V. The coil is 220 V AC 50 Hz, wide-range type, so it holds in across the 0.7 to 1.25 Uc operational band and drops out between 0.3 and 0.6 Uc. No built-in auxiliary contacts — the pole composition is 2 NO + 2 NC, meaning the main poles themselves handle the switching.
The rated breaking capacity is 144 A at 440 V, and the making capacity is 180 A at 440 V AC — both per IEC 60947-4-1, so it can close into and interrupt fault currents up to those levels without welding or failing. The power circuit impedance is 2.5 mOhm at Ith 32 A 50 Hz, which translates to about 2.6 W dissipation per pole in AC-1 duty — a number to check against your panel thermal budget if you are packing multiple contactors in a small enclosure. The maximum operating rate is 1800 cycles per hour at 60 °C. For a resistive load switched infrequently (a few times a day), that electrical endurance is effectively a lifetime rating. For a fast-cycling heater bank, you will want to check the duty cycle against the thermal curve.
The 45 mm width and 74 mm height mean it takes three standard 17.5 mm module spaces on the rail. Depth is 80 mm, which clears most shallow enclosures. Screw clamp terminals on both power and control circuits: power side accepts 1 to 6 mm² solid or 1 to 4 mm² flexible with ferrule; control side accepts 1 to 4 mm². Tightening torque is 1.2 N.m for both — a standard small screwdriver setting.
