Schneider Electric (Square D) LRD32 Thermal Overload Relay 23-32A

The Schneider Electric (Square D) LRD32 Thermal Overload Relay operates as an essential protection system which monitors electric motors by triggering circuit interruption after detecting extended periods of excessive current flow. The system works through bimetallic strips which bend because of the heat from current flow and when the current reaches dangerous levels the strips bend more which activates the tripping mechanism to stop motor power. The system operates as a protection part for motors in HVAC equipment including air conditioning units and heat pumps and ventilation fans.
