Schneider Electric (Square D) LR2D3557 Thermal Overload Relay 50A

The Schneider Electric (Square D) LR2D3557 Thermal Overload Relay operates as a protective system which safeguards HVAC equipment motors from overcurrents and phase failures. The relay system tracks motor current consumption until it reaches 50A where it activates to cut off power supply protecting the motor. The system operates as a protective mechanism with motor starters throughout HVAC equipment including air conditioners and ventilation fans and pumps. The system protects equipment from damage by stopping power supply when motor current exceeds 50A. The relay includes adjustable current settings which allow users to manage different types of motor loads.
