FAQ
What is the main function of a circuit breaker?
A circuit breaker is used to automatically cut off the electrical circuit when faults such as overload, short-circuit, and undervoltage occur, protecting the safety of electrical equipment and wiring.
How to select a circuit breaker with an appropriate rated current?
It is necessary to determine based on the normal operating current in the circuit and the maximum current that may occur. Generally, ensure that the rated current of the circuit breaker is greater than the normal operating current.
Why does the circuit breaker trip frequently?
Possible reasons include circuit overload, short-circuit, leakage, or a fault in the circuit breaker itself. It is necessary to check the circuit and equipment to determine the specific cause.
Is the breaking capacity of a circuit breaker important?
It is extremely important. The breaking capacity determines whether the circuit breaker can safely cut off the short-circuit current. Select one suitable for the maximum potential short-circuit current.
Can I replace the circuit breaker by myself?
If you have electrical knowledge and can ensure safety, you may try; however, it is recommended that a professional electrician perform the operation for correct installation and electrical safety.
How long is the delivery time?
Custom-made products will be shipped within 15-30 days, and in-stock products will be shipped within 3 days. The delivery date is subject to the arrival time of the freight forwarder.
