The Schneider Electric LC1E38004Q7IN is a 4-pole (4NO) contactor from the Easy TeSys Control range, rated for AC-1 resistive loads up to 60 A at ≤415 V. The 4 normally-open poles give you four independent switching paths in a single 56 mm wide package.
Because it's obsolete, there is no direct factory successor order code listed. If you need a like-for-like swap, the closest functional match would be a current-production 4-pole contactor from the TeSys Deca or TeSys F range with similar AC-1 current rating and DIN-rail footprint — but verify the mounting dimensions and coil voltage against your panel layout before committing.
The AC-1 utilisation category tells you this contactor is designed for resistive loads — think heaters, incandescent lighting, or resistive banks — where inrush current is minimal and the switching duty is straightforward. If your load is inductive (motors, transformers, ballasts), you'd need an AC-3 or AC-4 rated contactor instead, as the switching stresses differ significantly. The 4P (4NO) configuration means all four poles are normally open, so the contactor closes all circuits when the coil is energised. This suits applications where you need to switch multiple resistive loads simultaneously or break all four lines of a single-phase or three-phase resistive circuit. The 56 mm width and 93 mm depth fit standard DIN-rail enclosures, but the 64 mm height is slightly taller than some compact contactors — check your enclosure lid clearance. This means it meets the international safety and performance requirements for low-voltage switchgear and controlgear.
