Nader Circuit Breaker

Low-voltage circuit breakers are installed properly, which directly affect the performance and safety. It is generally noted that the following problems: (1) before installation, check Circuit Breaker plate listed on the technical parameters are consistent with requirements. (2) Low-voltage circuit b...

Correct selection of the electrical system of the low-voltage circuit breakers used, usually the following factors should be considered: (1) the nominal operating voltage and current. When selected, the rated working voltage (UN) is not lower than the rated line voltage, rated current can not be less...

Common circuit breakers are commonly used for the AC circuit and off, whether for a direct current, DC current key is the ability to cut. For alternating current, while the breaking of the contacts, an arc will be generated, i.e., a so-called "arcing." However, the characteristics of the alternating ...

1P, 1P + N and 2P circuit breakers are used for single-phase power control and protection circuit, then what is the difference between them, apply effects exactly what difference will it make? A, 1P, 1P + N and 2P defined breaker A, 1P breaker - single-pole circuit breaker having a thermal trip funct...

Low voltage circuit breaker or automatic air switch automatically called air circuit breaker, a low-voltage distribution networks and electric drive system commonly used in electrical power distribution. It combines a variety of control and protection functions in one, under normal circumstances can ...
