FAQ
1
How long is the delivery time for the product?
The delivery time for our company's products is generally 30-45 days, but it also depends on the complexity of the product and difficulty of the manufacturing process. For specific situations, you can consult our employees when placing an order.
2
Are you trading company or manufacturer?
We are a power manufacturer and exporter of Industrial Electric Equipment.With over 40 years of manufacturing experience, we have honed our expertise in producing high-quality electrical products. Our experience has enabled us to refine our processes and deliver reliable solutions to our customers.
3
What is the difference between a fuse and a circuit breaker?
A fuse is a one-time-use device that melts to break the circuit, while a circuit breaker can be reset after tripping.
4
What is a residual current circuit breaker (RCCB) and what is its main function?
A residual current circuit breaker (RCCB) is an electrical protection device. Its main function is to detect the residual current (leakage current) in the circuit and quickly cut off the power supply, thereby preventing electric shock accidents and fire hazards caused by leakage.
5
What is the difference between a miniature circuit breaker and a residual current device (RCD)?
A miniature circuit breaker primarily prevents circuit overloads and short circuits; a residual current device specifically detects leakage currents to prevent electric shock hazards. Modern homes typically combine both (using an RCBO or installing an RCD at the main switch) to provide comprehensive protection.
6
In which scenarios is an air circuit breaker (ACB) typically used?
ACB is mainly used in low-voltage power distribution systems, such as power plants, substations, industrial workshops, and high-rise buildings, to protect generators, transformers, and other key electrical equipment.
7
What are the key advantages of using an air circuit breaker (ACB) in power systems?
It has strong arc-extinguishing ability and can quickly cut off fault current.
It has a large breaking capacity, suitable for high-current working conditions.
It is easy to maintain and has high reliability in long-term operation.
