The air switch is different from the fuse
Fast fuse fuse current is generally selected 1.5 to 2 times the load current, overcurrent 2 to 3 times can be quickly blown, and anti-time characteristics of steep, arc breaking ability, especially for power electronic device protection and DC circuit protection
the air circuit breaker fast tripping over-current is generally 10 times, with anti-time characteristics, over-current multiples, action delay is long, do not have a small multiple over-current quick-break protection
For line protection cut off and power on.
Air switch is mainly to prevent over-current, loss of pressure, over voltage, short circuit, timely disconnect the load
