The waterproof box acts on the waterproof and dustproof shell, and is mainly used to prevent the objects in the box, such as lines, meters, instruments, etc., from entering the water and affecting its performance.

The development of waterproof box With the requirements of urban power and communication construction requirements for wire and cable, communication cable and signal cable buried, it is a very important proposal to provide solutions for cable branching, connection, waterproofing, etc.

Miniature circuit breakers are different from ordinary Miniature circuit breakers. Its advantages are small size, easy operation and many types and categories. For everyone, it can provide a variety of personalized options to achieve the desired effect. However, this must also be based at an early stage on knowledge of the basic sector in order to ensure adequate experience. Today I introduce you to the Miniature circuit breaker.

miniature circuit breaker, referred to as MCB, is the most widely used terminal protection appliance in building electrical terminal power distribution devices.

What is the difference between Miniature circuit breakers and other products of the same type?
The Miniature circuit breaker can be used to distribute electrical energy, rarely start asynchronous motors, and protect power lines and motors. In case of severe overload or short circuit and undervoltage errors, they can automatically switch off the circuit. Its function is equivalent to a backup type. Combination of switch and overheating relay, etc. In addition, it is generally not necessary to replace the components after the residual current is interrupted. At present, the miniature power switch is widely used.

A Miniature circuit breaker refers to mechanical switchgear capable of connecting, conducting and interrupting current under normal circuit conditions and of producing, conducting and interrupting current for a specified period of time even under certain abnormal circuit conditions.
