Do you know what a circuit breaker is? A circuit breaker is an instrument that can realize circuit switching. This kind of equipment is generally suitable for installation on switching devices and can realize power distribution. The function of the circuit breaker is relatively simple, mainly as a current protection device. Circuit breakers are installed in most circuits, which can effectively prevent various man-made disasters caused by circuit burnout or excessive voltage. What are the functions of the circuit breaker?

A Residual Current Circuit Breaker is an electrical safety device that is mainly used to protect electrical circuits. It has the ability to monitor the residual current in the current loop. Once a current leakage is detected (such as when the line has an insulation fault or the human body touches the circuit), it can quickly cut off the circuit to ensure personal safety.

Protecting your refrigerator from high voltage is essential to prevent damage to the appliance and ensure its longevity

Leakage circuit breakers, also known as residual current circuit breakers (RCCBs) or ground fault circuit interrupters (GFCIs), are electrical devices designed to protect against electrical shocks and fires caused by ground faults or leakage currents. These currents can occur when there's an unintended path for current to flow from the circuit to the ground, potentially putting people and property at risk. There are two main types of leakage circuit breakers:

A circuit breaker and a Molded Case Circuit Breaker (MCCB) are both devices designed to protect electrical circuits from overloads and short circuits.
