Nader Circuit Breaker

The rated peak withstand current (dynamic stability) of a high-voltage circuit breaker refers to the first half-wave current peak value of the rated short-term withstand current that the circuit breaker can carry under the specified use and performance conditions at the closing position. The duration...

The rated short-time withstand (thermally stable) current of a high-voltage circuit breaker refers to the effective value of the current that the circuit breaker can withstand when the circuit breaker is in the closed position during the rated short-circuit duration under the specified use and perfor...

The effect of current carrying capacity is mainly reflected in the Joule heat generated when the current flows through the conductor loop. Part of this heat is transferred to the outside world through heat conduction, heat convection and heat radiation, and dissipated into the surrounding medium, whi...

There are many factors that affect the performance of circuit breakers, which can be roughly divided into factors such as the influence on the circuit breakers current carrying capacity, the influence on the circuit breakers protection performance, and the influence on the short circuit characteristi...

Whether it is a leakage circuit breaker or an ordinary MCB, there are 1P and 2P points, and the classification principles are the same. When the 1P circuit breaker is disconnected, only one wire can be disconnected-the live wire. In other words, when the circuit breaker is opened, the neutral line is...
