Nader Circuit Breaker

1, the working principle and structure of low voltage circuit breaker switches, commonly known as air, low-voltage electrical switch with a main power grid may be switched on or breaking normal load current, motor current, overload current, short-circuit current is not applied to frequent operation l...

Circuit Breakers commonly known as automatic air switch. Low voltage distribution network is one of the main switching device, the low pressure switch is a switch best performance. It can be used to turn on, breaking the normal load current, and has a function of automatic protection circuit. When th...

Section Overview First, the definition of low-voltage circuit breakers, and perform standard classifications (a) is defined using a low voltage circuit breaker for low voltage power [AC (50Hz or 60Hz rated voltage and below 120, and the DC rated voltage of 1200v .] below the electrical power distribu...

The loss-of-voltage release of the automatic air switch of the power supply system is an electromagnet. At the moment of loss of power, the armature is released under the drive of the spring, and then the trip mechanism is driven, and the air switch completes the tripping operation. In the event of l...

Low-voltage circuit breaker is also called air switch or automatic switch, which is equivalent to a combination of knife switch, fuse, thermal relay, over-current relay and under-voltage relay, etc. It is a kind of manual switch function and can automatically perform under-voltage and loss-voltage. ,...

In practical applications, whether to choose a circuit breaker or a fuse should be selected according to local conditions based on the fault characteristics of low-voltage distribution lines, work needs, and the comprehensive analysis of the advantages and disadvantages of the two low-voltage protect...

Differential coordination means that there should be a certain gap between the upper and lower protective appliances in the network in the setting of the electrical action value. When a short circuit or overcurrent fault occurs at a certain point in the network, whether the protective appliance is a ...
