Run capacitor Start Relay.The start relay turns the compressor on when the in-unit thermostat calls for cooling, then disconnects power when the desired box temperature has been reached. These relays can be an electromechanical style, like a current relay, or a solid-state PTC that has no moving parts.Embraco designed a proprietary electronic relay that we …
However, both are experiencing compressor start up on a call for cooling. I replaced the OEM capacitor and thermal overload relay with a Supco 810. Checked compressor pin resistance to verify start and run winding loops. Hooked it up. cleaned condenser coil and evaporator coil. Check defrost cycle for correct operation.
Capacitor bank protection 1. Unbalance relay. This overcurrent relay detects an asymmetry in the capacitor bank caused by blown internal fuses, short-circuits across bushings, or between capacitor units and the racks in which they are mounted. Each capacitor unit consist of a number of elements protected by internal fuses.

Tips for using the thermal overload relay. The thermal overload relay can only be used as overload protection for controlling the motor, not as short-circuit protection. The rated current of the protected object must be known during installation, and the selected specification must be +20% of the rated current.
