Schneider Electric LR1F105L General Purpose Relay

Schneider Electric LR1F105L is a Telemecanique LR1-series thermal overload relay that provides adjustable overload protection for three‑phase motors in motor-control circuits when used with LR1 contactors. The F-range model LR1‑F105L offers a protection setting of 65 to 105 A, enabling precise motor protection across a broad load range. It is designed to mount as part of a compatible LR1 starter assembly, delivering thermal overload sensing that trips if motor current exceeds the set value to safeguard windings from overheating. Typical applications include conveyors, pumps, fans, and other three‑phase machinery where reliable overload protection is essential. As a component of the LR1 family, the LR1F105L is intended for industrial environments and coordinates with Schneider Electric LR1 contactors to form a complete motor‑control solution that protects motors without requiring additional, separate protection devices.
