The coil is 110 V AC, 60 Hz, so it's a drop-in for North American control voltage schemes running on 60 Hz line frequency. It's designed for motor control and resistive load switching, with utilisation categories AC-3, AC-3e, and AC-1. The AC-3e category adds an energy-efficiency dimension for premium motor applications, but the core spec remains the 50 A at 440 V AC-3. It also carries the full suite of EN/IEC 60947-4-1 and GB/T 14048.4 standards, so it's accepted in both European and Chinese panel builds.
Sourcing reality — obsolete but findable
Because it's obsolete, there's no official successor order code from Schneider for this exact variant. If you need a drop-in replacement with the same footprint and coil voltage, the closest active sibling in the Easy TeSys range would be the LC1E50... series with a 110 V 50/60 Hz coil — but verify the mechanical interlock and auxiliary contact compatibility for your panel. The mounting dimensions (75 mm width, 114 mm depth, 127 mm height) and DIN-rail/plate mounting are standard across the family.
Deployment context — panel integration and environmental limits
The IP2X rating means finger-safe from the front but not sealed — keep it inside an enclosure, not in a washdown zone. Operating ambient temperature is -5 to 55 °C with the coil at rated voltage; storage range is -60 to 80 °C, which matters for warehousing but not for running.
