The Schneider Electric LC1E25004N5WB is a 4-pole normally-open contactor from the Easy TeSys Control range, rated for 40 A in AC-1 utilisation category (resistive load) at up to 440 V AC. The coil is a wide-range AC type at 50 Hz, pulling 95 VA inrush at 20 °C, and holds in at 415 V AC nominal. Mounts on DIN rail or a plate, so it fits standard panel layouts. The 4 NO pole configuration means all four contacts close when the coil is energised — no auxiliary contacts built in, so if you need feedback to a PLC or a holding circuit, plan for a separate auxiliary block.
The IP20 finger-safe enclosure protects against accidental contact but is not sealed against moisture; keep it inside a cabinet. Electrical durability is 350,000 cycles at AC-1, and mechanical durability is 10 million cycles. That is a long service life for a resistive-load contactor — the mechanical figure means the coil and armature will outlast the contacts in most applications. Maximum operating rate is 1,800 cycles per hour at 60 °C, so it can keep up with fast cycling processes like packaging or conveyor indexing.
Where this class of part is used
The 4-pole NO configuration is common for three-phase plus neutral switching, or for isolating two independent single-phase circuits. The Easy TeSys range is Schneider's economy line for straightforward on/off control without the advanced features of the TeSys D or F series.
