The Schneider Electric LC1E32004N5WB is a 4-pole contactor from the Easy TeSys Control range, rated for 45 A in AC-1 utilisation category at ≤440 V — that is the resistive-load rating, so it handles heaters, lighting banks, or transformer primaries at that current. The 415 V AC 50 Hz coil is a wide-range AC control circuit, meaning it pulls in reliably between 0.7 and 1.25 times rated voltage and drops out between 0.3 and 0.6 times rated. No auxiliary contacts are built in, so if you need feedback or a hold-in circuit, you will add a side-mount block.
The screw-clamp terminals accept up to 6 mm² on the power circuit and 4 mm² on the control circuit, with a tightening torque of 2.1 N·m for power and 1.2 N·m for control. That is enough for a 45 A resistive circuit using 4–6 mm² cable, but if you are paralleling conductors or using fine-stranded wire, verify the terminal range for your cable end. The TH protective treatment (conforming to IEC 60068-2-30) means it is tested for humid tropical conditions — useful if the panel sees condensation cycles.
