The Schneider Electric LC1E50B5 is a 3-pole contactor from the Easy TeSys Control range, rated for AC-3 duty at 50 A up to 440 V with a 24 V AC 50 Hz coil. Per the datasheet, it's built for motor control and resistive loads, and carries EN/IEC 60947-4-1 certification for the AC-3 switching category — meaning the 50 A figure governs inrush from a squirrel-cage motor starting, not just steady-state resistive current.
Mounts on either a plate or a DIN rail, so it fits standard panel layouts without adapters. The 75 mm width and 127 mm height keep it within a typical contactor footprint for this current class.
The AC-3 rating at 50 A is the headline number for motor switching — it's the current the contactor can make and break across a starting induction motor load. The AC-1 rating (resistive) and AC-3e rating (enhanced AC-3 for specific motor types) are also listed, giving flexibility for non-motor loads. The 24 V AC coil is a 50 Hz coil; verify supply frequency matches before specifying into a 60 Hz control circuit. That's a safety-relevant parameter for interlocking circuits where simultaneous closure of NC and NO paths must be prevented.
Ambient temperature range is -5 °C to 55 °C for operation, with storage from -60 °C to 80 °C. IP2X finger protection on the contactor body.
