Description

Circuit breaker convenient to install

Technical Field

The utility model relates to the technical field of circuit breakers, in particular to a circuit breaker convenient to install.

Background

A circuit breaker is an electrical device for protecting a circuit from abnormal conditions such as overload, short circuit, and earth leakage. It protects circuits and devices by automatically powering down the circuits. The main components of the circuit breaker comprise contacts, springs, magnetic coils, an arc chamber and the like. When the current is excessive, the contact can automatically jump, thereby cutting off the circuit. Circuit breakers are widely used in circuit protection in various locations such as residential, industrial, commercial, and public facilities.

The circuit breaker is an electrical equipment for protecting a circuit, and the working principle is that a controllable switch is added in the circuit, when abnormal current occurs in the circuit, the circuit breaker can automatically trip, and the power supply is cut off, so that the safety of the electrical equipment and personnel is protected.

However, the existing circuit breaker is generally connected to equipment through bolts in a threaded manner before being used, but is exposed to the outside for a long time, and the threaded connection part is easy to rust, so that the circuit breaker is not easy to detach when being detached, meanwhile, the circuit breaker is also installed through threads, and rust is generated after the circuit breaker is used for a long time, so that the circuit breaker is not easy to install; in view of this, we propose a circuit breaker that is easy to install.
