What Is the Definition of a HACR Breaker?
An HACR circuit breaker is a heating, air-conditioning and refrigerator breaker. The breaker provides overcurrent protection to combustion fans, exhaust controls, AC compressors and furnaces. A standard two-pole HACR breaker can safeguard HVAC equipment from electrical overuse, according toBuild My Cabin.
A circuit breaker is a switch that instantly stops a circuit's flow in case of an electrical overload. By responding to an overcurrent condition, circuit breakers safeguard homes from electrical shocks and fire. According to Home Depot, buying a circuit breaker entails knowing a breaker's load capacity as well as its limitations and compatibility. Safety and installation requirements should be considered also.
Standard circuit breakers track the electrical flow for appliances, lights and electronics. If a short or electrical overload is sensed, the breaker will trip and stop the current to prevent the wiring from overheating.
Single-pole breakers safeguard one energized wire and provide 120 volts of electricity to a circuit. Double-pole breakers are made up of two single-pole breakers, which feature a shared trip mechanism. Double-pole breakers provide up to 240 volts of electricity to a circuit and safeguard two energized wires. The double-pole breakers are used for larger appliances, such as washers and dryers, that require more electricity.
