SCHNEIDER ELECTRIC LR2K0302 - Thermal Overload Relay
The SCHNEIDER ELECTRIC LR2K0302 is a TeSys K series thermal overload relay engineered for electromechanical motor protection against sustained overcurrents and phase failure conditions. This device integrates directly with TeSys K contactors, providing robust thermal sensing for industrial motor control circuits, HVAC systems, and general machinery applications requiring reliable overload protection. It features a Class 10A tripping characteristic, suitable for standard motor starting times.
