Nader Circuit Breaker

Circuit breakers have short-circuit tripping and thermal tripping modes. Short-circuit tripping means that the huge current generated by a short-circuit fault in the circuit causes the short-circuit release to act quickly to disconnect the circuit to achieve the purpose of protection. Thermal trip me...

How to choose the size of the switch (breaker, etc.)? Generally, how much is more appropriate than the rated current? Generally choose 1.5 times to 2 times the load, the load capacity is large, the starting current is large and the starting current is large, and the starting current is selected 1.5 t...

The selection principle of the home circuit breaker is still based on the maximum operating current. That is, the maximum adjustable current of the selected MCB is greater than or equal to the working current calculated from the total power. Multiply the total current of the connected load by 1, 2 to...

The molded case circuit breaker(MCCB) has the two-stage protection function of overload long time delay and short circuit transient action. It can also be used in conjunction with module units such as leakage electrical appliances, measurement, and electrical operation. In low-voltage power distribut...

General small air switch specifications are mainly divided into 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A, 80A, 100A, etc. by rated current; In order to ensure safety and reliability, the rated operating current of electrical components should generally be greater than 2 times the required maximum l...
