Smartele SE63 Potential Relay 170V Universal Replacement

Product Description

The SMARTELE SE63 is a potential relay designed to provide additional starting torque to motors and compressors in refrigeration and air conditioning systems. It works by removing the start winding from the circuit once the motor reaches sufficient speed, protecting the winding from overload during a locked rotor condition. The SE63 operates at a continuous coil voltage of 170 volts and is compatible with both 50 Hz and 60 Hz systems. Licensed HVAC technicians and refrigeration service pros install this relay as a direct replacement for OEM potential relays in residential and commercial applications.

The SE63 is suited for use in residential and commercial air conditioning units, heat pumps, room air conditioners, and refrigeration compressors. Its universal design makes it a practical stock item for service technicians who need a reliable replacement across a broad range of equipment types without sourcing individual OEM parts for each unit.
