What problems should be considered when using low voltage circuit breakers?

1. Improper installation and adjustment

Whether the installation and setting are correct is one of the basic factors affecting the normal operation of the low voltage circuit breaker. There are many operational accidents because the product is not assembled, adjusted and put into operation strictly according to the manufacturer's regulations. In general, there are three situations: (1) The auxiliary switch is set incorrectly. (2) The screw is not tightened and the pin is not opened. (3) Improper placement of the sealing ring.

2. Improper operation and maintenance as well as incorrect operation

Improper operation and maintenance of low voltage circuit breakers is another important cause of operational accidents. There are three common aspects: (1) The oil circuit breaker has too little oil. (2) Poor insulation. (3) Poor mechanical maintenance.

What are the characteristics and functions of low voltage circuit breakers?

Features:

①The low voltage circuit breaker has strong switching power.

②The low voltage circuit breaker has good protective properties and can completely disconnect the line in a very short time.

③ The free release device of the low voltage circuit breaker has a locking effect. If the line does not return to normal state and the trigger does not return to its original position, it cannot be closed and powered.

Effect:

low voltage circuit breakers can not only turn normal load current and overload current on and off, but also turn short circuit current on and off. In addition to controlling the circuit, the low voltage circuit breaker also has certain protective functions such as overload, short circuit, undervoltage and leakage protection, etc.

How does the low voltage circuit breaker perform the drawer wiring?

The input and output drawers of the low voltage circuit breaker are rotated clockwise or counterclockwise by the rocker, and the insertion structure is adopted in both the main circuit and the secondary circuit, omitting the insulator required for the fixed type Machine can be used for two purposes. which improves efficiency, facilitates operation and maintenance, and increases safety and reliability. In particular, the main circuit contact holder of the drawer floor can be used together with the fuse contact holder of type NT, so that the fuse can be used directly for power supply in an emergency.
