PRODUCT DESCRIPTION
OMRON LR6-E-Y - Thermal Overload Relay
This is a thermal overload relay from the OMRON LR6 series, engineered for robust overcurrent and phase loss protection of three-phase AC motors. It utilizes bimetallic strips for reliable thermal sensing, ensuring motor longevity and operational safety in industrial control applications. Designed for direct mounting to contactors or DIN rail, it provides essential protection for pumps, fans, conveyors, and general machinery.
