Nader Circuit Breaker

Proper use and maintenance of low voltage circuit breakers must pay attention to the following issues: (1) the circuit breaker according to the provisions vertical small for connecting wires must meet the requirements. (2) Release setting values ​​are not arbitrarily change once after a good tune...

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...
