4 Things you need to know about circuit breakers

Numerous factors could cause you to have an electrical issue. The most frequent problem is a malfunctioning fuse or circuit breaker. High voltage or low voltage are additional factors. A circuit breaker is a device that halts current flow inside electrical circuits. It is possible that the issue is caused by a circuit breaker that is not working properly.

A circuit breaker allows electricity to flow through an electrical circuit in only one direction. It can protect the equipment and components of the circuit from excessive current, overvoltage or other damage. Circuit breakers are also known as fuses since they are similar to a fuse in appearance and operation.


There are several types of circuit breakers that you can use to protect your electrical equipment from overloads. They may be used to protect motors, transformers, or other equipment that an overcurrent can damage.

The most common types of circuit breakers are:

  1. Arc-Fault Circuit Breakers (AFCBs): These have a magnetic field that detects when a fault develops between two conductors, closing the circuit breaker immediately.
  1. Drum-Fault Circuit Breakers (DFCBs): These have a drum with a set of contacts that closes when an arc fault develops between two conductors, disconnecting the line.
  1. Surface-Mounted Conductors: These are mounted on a surface and interrupt all power flowing through them until resetting is performed by inserting an Allen wrench into a hole on one side of each contact pad.

How does it work?

A circuit breaker switches an electrical current flow from one part of the circuit to another, allowing electricity to flow through it but not through any other part of the circuit. Doing this prevents any kind of fire or damage to any other part of the electrical system.

The process begins when a sensor inside the breaker box detects a fault. The sensor detects this fault, a short circuit that can cause overcurrent or overheat because too many current flows through it. The sensor sends an alert signal to other sensors within the circuit breaker box, which then sends an alert signal back towards its control panel. This causes all breakers within this area (including those at each outlet) to become de-energized and isolated from their respective circuits until they are reset manually or automatically by an electrician working onsite with them during maintenance hours.


Here are just some of the benefits of using a circuit breaker:

  • It helps prevent damage from power surges.
  • It helps prevent damage from lightning strikes.
  • It helps prevent damage from short circuits.
  • It can reduce heat build-up in your devices by limiting the current flowing through them.
  • It helps prevent accidents caused by electrical fires.
  • It can help reduce costs associated with maintenance by identifying problems before they occur.
  • It can help keep your facility running smoothly by ensuring that the electricity flowing through your system is safe and effective.

Circuit breakers are a great way to protect your network from overloads and outages. These breakers can prevent data loss or network downtime caused by power surges, lightning strikes, and other events that can impact device connection. When it comes to electrical equipment, a circuit breaker is an essential part of a safe and efficient system. So, when buying a circuit breaker, research properly and choose the one based on your requirements.
