Nader Circuit Breaker

At present, many power companies, substations, and power distribution network industries in China have begun to use vacuum circuit breakers. This is mainly because the insulator and arc extinguishing medium of the circuit breaker are all vacuum, which has excellent insulation and arc extinguishing ef...

The shape of the analog-digital isolation switch and the micro-break (circuit breaker) are very similar. Micro break Micro-break is short for miniature circuit breaker. It is the most widely used terminal protection electrical appliance in building electrical terminal power distribution devices. With...

When the circuit breaker is used as upper and lower protection, its action should be selective, and the upper and lower levels should cooperate with each other, and pay attention to the following issues: 1) When the upper and lower actions of the circuit breaker are selective, attention should be pai...

When designing and selecting low-voltage circuit breakers, the general principles that need to be considered are: Determine the type of circuit breaker to be selected according to the load nature, fault category and line protection requirements of the low-voltage power distribution system, and comply...

The circuit breakers that can be seen in the family are generally only 1P and 2P. 1P and 2P are also called level 1 and level 2. Each level corresponds to two upper and lower terminals, and the width of each level is 17.5 mm (for example, 2P circuit breaker) The width of the device is 17.5*2=35mm). T...
