FAQ
1. What is an ACB (Air Circuit Breaker)?
An ACB (Air Circuit Breaker) is a protection device used in low-voltage power systems. It can quickly cut off the current when a circuit fault occurs, protecting equipment and personnel from electrical hazards. It uses air as the medium to extinguish the arc, making it a commonly used switching device in electrical systems.
2. What is the difference between ACB and MCCB?
Both ACB (Air Circuit Breaker) and MCCB (Molded Case Circuit Breaker) are used for protection in electrical systems, but they are suitable for different current ranges. ACB is generally used in high-power, high-current electrical systems, while MCCB is suitable for medium to small-sized electrical systems. ACB has a higher rated current, usually used for applications above 500A, whereas MCCB is typically used for lower currents.
3. What is the working principle of an ACB?
The working principle of an ACB is based on the air medium arc-extinguishing principle. When a circuit fault occurs, the contacts inside the ACB open, and the arc forms in the air and is quickly extinguished. To prevent the arc from causing a fire or damaging equipment, the ACB is designed with a forced air cooling system and arc-extinguishing devices to rapidly extinguish the arc.
4. What are the differences between the three products W1, W2 and W3?
a. W1 is a standard model, suitable for most conventional applications, with high cost performance and mature and stable structure.
b. W2 is a thin and light model, with lighter weight and more compact size, suitable for occasions with requirements for installation space or weight.
c. W3 is a high-voltage and high-performance model, suitable for occasions that require higher voltage levels and stronger load capacity, with better performance.
5. How to choose the product model that suits me?
You can choose according to your installation environment, electrical parameter requirements and budget:
a. If you pursue maturity, reliability and strong versatility, choose W1.
b. If you have high requirements for space and weight, choose W2.
c. If you have high requirements for voltage level and performance, choose W3.
d. If you need help, please contact our technical support team and we will provide you with selection suggestions.
6. Are the warranty and after-sales service of these three products the same?
Yes, W1, W2, and W3 all enjoy the same warranty period and perfect after-sales service. For specific warranty terms, please refer to our "Product Warranty Policy".
