Trane RLY3148 Start Relay 50A 383V

Trane RLY3148 Start-Relay is a vital part of electrical hardware involved within the operation of HVAC systems of motors, especially compressor motors. It serves as a switch to power the motor's starting winding to get the start up. When the motor reaches its operating speed the relay de-energizes the starting winding. This tight control means a smooth, efficient starting of the motor both eliminating stress on the motor and preventing damage. The start relay optimizes motor performance and thereby contributes to improved system efficiency, longer equipment and reliable operation of the HVAC system.
