The Schneider Electric LC1E50E5 is a three-pole EasyPact TVS contactor from the Easy TeSys Control range, rated for AC-3 motor switching at 50 A up to 440 V with a 48 V AC coil. It's built to handle motor control and resistive loads, with a mechanical life that holds up to vibration at 3 Gn when closed and shock at 7 Gn for 11 ms — so it's comfortable on a conveyor line or pump panel that sees regular starts and stops.
The 48 V AC coil means it needs a control transformer if your panel runs 24 VDC or 120 VAC; verify the control voltage before wiring.
The TH protective treatment (pollution degree 3) per IEC 60068-2-30 means it can handle humid, non-condensing environments, but the IP2X front face still keeps fingers out.
Ambient temperature range is -5 °C to 55 °C during operation, with storage from -60 °C to 80 °C — if the panel sits in an unheated warehouse, the storage range is generous, but make sure the panel stays above -5 °C when running.
