Type and selection of Circuit Breaker

Update date:2017-12-26 Source:maxge

Any neglect protection circuit design of electrical or electronic products are buried hid the problems. Shelter your expensive equipment in the end is to check for including control switch, electrical, and the power of the entire electrical system to shelter, the Chinese New Year eve in order to avoid short circuit and current situation, the main circuit breaker today are thermal circuit breakers, magnetic circuit breaker and flux leakage circuit breaker etc. When choosing a circuit breaker, the designer not only has to think about the characteristics of the circuit, but also to consider the limitations of the setting and the casing size of the circuit breaker.

Choice must be for a specific application of appropriate circuit protection device is not hard, but it does need a bit to contemplation. If electrical and electronic equipment adopted in the design specifications of partial loose circuit protection device, the equipment will be easily damaged by impact power and led to the disastrous consequences of the fire, on the contrary, if the use of a strict circuit protection device, the frequency of the undesirable frequency will be triggered.

The main circuit breaker today are thermal circuit breakers, magnetic circuit breaker and flux leakage circuit breaker etc. When choosing a circuit breaker, the designer not only need to consider the following circuit characteristics, also should consider including the installation position of circuit breaker and the shell size restrictions:

Low pressure rated AC or DC voltage

 

When single phase, multiphase and pole number

 

Low applicable national electrical length scales and peace management institutions

 

Low short circuit breaking capacity
