Thermal Overload Switch For Compressor

Thermal Overload Switch For Compressor FAQ

What is a thermal overload switch?

While manual-reset thermal-overload switches are most common on heating systems such as oil burners and some fan motors, air conditioner electric motors and compressor motors and submersible well pump motors are an example of motor designs that may be use a thermal overload switch that resets itself automatically when the motor has overheated.

What is ac compressor thermal overload?

AC compressor thermal overload is a common cause of malfunction, and typically happens on the hottest (or coldest) days of the year, when your system is working overtime. Responsible for 49 percent of component failures, it is a serious problem – and also one of the most expensive if it progresses to compressor failure.

How does a thermostatic overload relay work?

Thermal overload relays perform the following functions: Allow harmless temporary overloads (such as motor starting) without disrupting the circuit. Trip and open a circuit if the current is high enough to cause motor damage over a while. Can be reset once the overload is removed.

What is a compressor overload protector and how does it work?

Adding a compressor overload protector can safeguard your HVAC system. Located nearby the condenser, this special sensor monitors temperatures, shutting down the compressor temporarily to prevent it from overheating.
