Schneider Electric LR9F5363 Thermal Overload Relay

Schneider Electric TeSys LR9F5363 is a three‑pole electronic thermal overload relay that provides motor protection by monitoring current in the 48–80 A range with a Class 10 thermal trip. It is part of the TeSys LRF family and uses a control/coil voltage of 17–32 V, with an auxiliary signaling contact of 1 normally open and 1 normally closed (1 NO + 1 NC). Designed for direct mounting under TeSys F contactors (for example LC1F115, LC1F150, LC1F185) or on an LA7 mounting plate for standalone use, LR9F5363 offers compact, integrated protection for three‑phase motors in pumps, fans, conveyors, and similar applications. Schneider Electric discontinued LR9F5363 on June 30, 2024, and recommends LR9G115 as the replacement for new designs, covering a broader 28–115 A range while maintaining TeSys F compatibility. The product remains supported for existing installations with spare parts and service but is no longer sold as a current catalog item. This LR9F model carries the TeSys protection lineage, providing reliable motor protection within Schneider Electric’s TeSys ecosystem and simplifying panel wiring for protected motor circuits.
