The Difference between Recloser and Circuit Breaker

28th Apr 2022

If you’re wondering how to tell the difference between a recloser and a circuit breaker, keep reading to learn more about these two types of electrical protection devices. Reclosers are typically used to protect a high-cost fuse during transient faults. The circuit breaker, on the other hand, is more likely to interrupt the supply to consumers. 

Reclosers are less expensive than circuit breakers, but their main function is to restore power to a circuit after an outage. They work with other high-voltage appliances to identify the source of the fault, and they can also minimize the area of a power outage. Circuit breakers, on the other hand, protect against overheating and fires. They operate quickly after an outage, so they can restore power fast.

A recloser is a self-regulating device that automatically opens and closes in the event of a short circuit on a line. It is designed to automatically open and close after a pre-determined number of openings. It can also be set to close after a certain number of interruptions.

What is a Recloser?

Reclosers are electric circuit breakers used to protect power lines from temporary faults. Most faults on power lines occur as a result of a fuse blowing, tree branch contact, equipment failure, or lightning. Often, reclosers will open the circuit and retry the closing operation when a fault occurs. Unlike fuses, a recloser can isolate the fault and deliver energy to burn it off.

Reclosers can help improve network reliability and quality. Many European countries have implemented reclosers that incorporate damage indicator technology. A sensor-equipped recloser will reduce the time it takes to detect and repair the damage, allowing consumers to receive power quicker. 

A Recloser can be either manual or automatic and works to restore power to a circuit after a power outage. It has special circuitry and works much like a thermostat on your home’s heating system. It detects if there’s too much current flowing through the electrical panel and opens when that excess current has been removed. The recloser then closes itself when the current level reaches normal levels.

What is a Circuit Breaker?

The basic circuit breaker is a simple switch that connects a moving contact to the bottom terminal of a bimetallic strip. It is a device that protects your appliances against power surges or fluctuations. It is designed to protect sensitive semiconductor devices and measuring circuits. Its maximum fault current allows it to use more efficient devices on systems. The breaker is often installed in commercial buildings and can develop a large short circuit current. 

One of the most common reasons why circuit breakers trip is that there’s too much current flowing through the wires in a home. Overloaded wires can easily lead to a fire or burned-out appliances. A circuit breaker will protect you by shutting off the electricity to the entire house or to a particular zone, as determined by its size, electrical load, and a number of outlets. 

Circuit breakers are designed for a specific capacity, so they are designed to match the amount of load that a wire can carry. For example, a tumble dryer and dishwasher connected to the same circuit are expected to draw more than 20 amps. Circuit breakers are designed to trip before excessive heat builds up on the wires, preventing a fried appliance. 

The Difference between Recloser and Circuit Breaker

There are several differences between circuit breakers and reclosers. A circuit breaker typically uses a spring mechanism to open and close. A recloser has a permanent magnet mechanism and has fewer parts, is maintenance-free, and can automatically open and close a circuit. Both circuit breakers and reclosers have control systems that are separate from each other. The recloser is designed to protect against overheating and is a self-contained unit.

A recloser cooperates with other high-voltage electrical appliances to minimize the power failure area. A circuit breaker breaks the circuit when it detects a short circuit and is only made up of an operating mechanism and a vacuum interrupter. Both devices utilize permanent magnets or springs to neutralize inductive current. A recloser is designed to prevent damage to electronic devices, while a circuit breaker is designed to interrupt power and restore power after a power outage.

The difference between circuit breakers and reclosers is important to understand when you need one or the other. Reclosers generally provide more protection against overheating, fires, and electrical equipment but are often less expensive than circuit breakers. Reclosers typically restore power faster in case of an outage and can prevent the spread of fire. While both circuit breakers and reclosers have their benefits, they are not necessarily the same. The difference between circuit breakers and reclosers is largely a matter of preference.

While both circuit breakers are useful, one is better than the other for many situations. For instance, circuit breakers prevent overheating in a residential building if a tree limb falls on the power line, while a recloser prevents fire by interrupting the flow of electricity through a circuit. A circuit breaker can shut off the power to a whole building. A circuit breaker also protects the wiring from water exposure, short circuits, and overcurrents.
