Air switch is a kind of circuit breaker, so how to distinguish between circuit breaker and air switch? What is the difference between a circuit breaker and an air switch?
1. The difference in voltage level
Generally, the applicable voltage level of air switch is below 500V, and the circuit breaker can usually be applied to various voltage levels above 220V.
2. The difference in the ability to interrupt current
Generally, circuit breakers can withstand more load and short-circuit current.
3. The difference between arc extinguishing medium and method
The arc extinguishing media and methods of circuit breakers include not only air circuit breakers, but also vacuum circuit breakers, more oil circuit breakers, less oil circuit breakers, and sulfur hexafluoride circuit breakers.
4. The difference between supporting equipment
Generally speaking, the measurement, logic, and execution parts of the circuit breaker are more complicated than the circuit breaker.
5. The difference in function
Air switch generally plays the role of "isolation" and "protection device" in low-current circuits; circuit breakers automatically trip when the circuit is short-circuited and high current. In high-voltage, high-current circuits of electronic products, it is often used as a power failure, Power on, connect and disconnect the operating electrical appliances of the load.
