Circuit Breakers 101: Understanding the Basics

Circuit breakers are an essential component of any electrical system. They are designed to protect electrical circuits from damage caused by overloading or short-circuiting. Circuit breakers come in different types and sizes and can be used in residential, commercial, and industrial applications.

When choosing a circuit breaker, it is crucial to consider the amperage rating, voltage rating, and interrupting capacity. The amperage rating indicates the maximum current load that the circuit breaker can handle without tripping, while the voltage rating indicates the maximum voltage that the circuit breaker can safely interrupt. The interrupting capacity indicates the maximum fault current that the circuit breaker can safely interrupt without causing damage to the electrical system.

We spent countless hours researching and testing various types of circuit breakers to identify the ones that offer the best protection and performance. Whether you are looking for a circuit breaker for your home or business, our guide will help you make an informed decision.
