Leakage protection circuit breaker electric mcb box function: when human body shock or equipment leakage, quickly cut off the power supply circuit, so as to avoid harm to human body and equipment.
Leakage protection circuit breaker used to be called leakage circuit breaker, is to prevent the human body in the low-voltage line electric shock or leakage caused by fire, explosion accident of a switching appliance. Common types are electromagnetic current action type, voltage action type and transistor (integrated circuit) current action type.
When the detecting element receives the signal, the leakage release disconnects the main contact of the main circuit to protect it. The protective action current of detection element and leakage release is 30~100mA, and the protective action time is 0.03~0.1s.
There are two main functions of circuit breakers electric mcb box in power grid:
(1) Control effect. That is, according to the operation needs, put in or cut off part of the power equipment or line.
(2) Protective effect. That is, when the power equipment or line fails, the fault part can be quickly cut off from the power grid by relay protection and automatic device acting on the circuit breaker, so as to ensure the normal operation of the non-fault part of the power grid.

The distribution box Electric Mcb Box has the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, no site restrictions, common application, stable and reliable operation, high space utilization, small footprint and environmental protection effect. It is the control center that instructs various components in the power supply line to reasonably distribute electric energy, and is the control link that reliably receives the upper-end power supply and correctly feeds out the load electric energy. Improving the operational reliability of the power distribution box is the goal of creating a high-quality project.
