The Schneider Electric LC1E09004M5WB is a 4-pole contactor from the Easy TeSys Control range, rated for resistive-load switching at 20 A AC-1 (≤440 V). It carries four normally-open (4 NO) power poles and no built-in auxiliary contacts. This contactor is built to EN/IEC 60947-4-1 and GB/T 14048.4, so it's certified for motor-starter and general switching duty in panels destined for both European and Chinese markets.
Screw-clamp terminals accept 1 to 4 mm² solid or flexible wire on the power circuit. Heat dissipation runs 2 to 3 W through the control circuit at steady state, and each pole dissipates 1.6 W under AC-1 load.
The headline rating is 20 A at ≤440 V AC in AC-1 utilisation category — that's resistive load, like heaters or incandescent lighting banks. For motor loads (AC-3), you'd need to derate significantly. The maximum operating rate is 1800 cycles per hour at 60 °C, which is about one cycle every two seconds — fast enough for most process cycling but not for high-speed pick-and-place.
