Schneider Electric (Square D) LRD3355 Overload Relay 30-40A

The Schneider Electric (Square D) LRD3355 Overload Relay operates as an essential electrical protection part which protects motors in HVAC equipment through current draw monitoring and circuit breaker tripping during overload conditions. The thermal-magnetic relay operates through a bimetallic strip which bends because of high current to activate a tripping system that breaks the power supply to defend motors from damage. The protects air conditioning units and heat pumps and ventilation systems by offering essential benefits which include protecting motors from expensive failures and minimizing equipment downtime. The system allows users to set current levels between 30-40A for different motor needs which improves safety and operational efficiency.
