The Schneider Electric LC1E32004E7IN is a 4-pole (4NO) contactor from the Easy TeSys Control range, rated for AC-1 resistive loads up to 55 A at ≤415 V with a 48 V coil. The AC-1 utilisation category means this contactor is rated for switching resistive loads with minimal inrush — so the 55 A figure is the steady-state current it can make and break without accelerated wear. For motor or inductive loads you'd need an AC-3 or AC-4 rated part.
No official successor order code is listed in the lifecycle record, so a direct drop-in replacement isn't confirmed. A cross-reference to a current Easy TeSys or TeSys Deca variant would need to be validated against the same 4P, 55 A AC-1, 48 V coil spec and the DIN-rail footprint.
The contactor complies with EN/IEC 60947-1, EN/IEC 60947-4-1, and EN/IEC 60947-5-1, plus the Chinese GB/T equivalents — so it's accepted across European and Asian installations that follow those standards. IP2X finger protection per IEC 60529 means the contactor body prevents access to live parts with a finger probe — standard for enclosed panel mounting. Operating altitude is rated to 3000 m without derating.
