The Schneider Electric LC1E40004N7IN is a 4-pole contactor from the Easy TeSys Control range, rated 72 A in AC-1 utilisation category at ≤415 V. AC-1 covers resistive loads — heaters, lighting banks, non-inductive elements — not motor starting. The four normally-open poles switch the line side; there are no built-in auxiliary contacts on this base unit. It complies with EN/IEC 60947-1, 60947-4-1, and 60947-5-1, plus the Chinese GB/T equivalents — so it carries the certifications for a panel destined for European or Asian markets.
The 72 A AC-1 rating is the continuous resistive current the contactor can carry without exceeding its thermal limit. For a panel feeding a 60 A three-phase heater bank, this contactor has headroom. But do not apply it to a motor load — AC-3 or AC-4 duty would require derating, and the contactor is not specified for those categories. It belongs inside a panel, not on a washdown line or outdoors.
Sourcing posture
If your BOM line is locked to LC1E40004N7IN and you need to keep a production line running, the smart move is to secure enough units now to cover your remaining service life — or to begin the requalification process for a current-production replacement. We can quote against an RFQ with the available quantity and condition grade.
