Nader Circuit Breaker

The following points should be considered when selecting a circuit breaker. (1) The rated current and rated voltage of the circuit breaker should be greater than or equal to the rated current and rated voltage of the circuit. (2) The rated current of the trip unit of the circuit breaker should be gre...

(1) Electromagnetic release When the current flowing is within the setting value, the suction force generated by the coil of the electromagnetic trip unit is not enough to attract the armature. When a short-circuit fault occurs, the short-circuit current exceeds the set value, and the attractive forc...

The SF6 circuit breaker adopts a self-energizing arc extinguishing structure, which mainly uses the high-pressure thermal expansion airflow in the pressure cylinder and the blocking effect of the hitting arc to increase the gas pressure in the high-pressure cylinder at the opening of the circuit brea...

Circuit breaker is a kind of load switch, which has short-circuit and overload protection functions, and its short-circuit protection function is realized by electromagnetic coil. Because of its complete protection function, easy maintenance and use, it is widely used in power systems. This article i...

Whether a circuit breaker can operate effectively and reliably depends to a large extent on the performance and quality of the operating mechanism. Therefore, depending on the circuit breaker, the operating mechanism equipped with it should meet the required nature and reliability, mainly as follows:...
