The LC1E25004B7IN is a 4-pole (4NO) contactor from Schneider Electric's Easy TeSys Control range, rated 50 A in AC-1 utilisation category at ≤415 V with a 24 V coil. AC-1 means it's designed for resistive loads — heaters, lighting banks, non-inductive elements — not motor starting. The 4 NO poles give you four independent switching paths, useful for multi-circuit resistive banks or as a main contactor in a resistive load panel.
Sourcing reality — this part is obsolete
Schneider has marked the LC1E25004B7IN as obsolete. No official successor order code is listed, so the replacement path is not a simple cross-reference.
Physical fit and integration
The contactor measures 56 mm wide by 64 mm high by 93 mm deep, and mounts on either a plate or a DIN rail. At 93 mm depth, it projects further from the rail than a typical compact contactor — factor that into enclosure depth and gland-plate clearance. IP2X protection means the housing is finger-safe but not sealed against dust or moisture; keep it inside an IP54 or better enclosure in any industrial environment. The protective treatment is TH (pollution degree 3) per IEC 60068, so it handles the conductive-dust conditions common in light-industrial panels.
Standards and compliance footprint
Fire resistance is rated to 850 °C per IEC 60695-2-1, so it meets the glow-wire test for unattended equipment. Operating altitude is 3000 m, which covers most high-altitude installations without derating.
