Q:Is this an air switch or a leak protector?

The second with overload protection. Short circuit protection and leakage protection of the RCD. Also known as leakage circuit breaker.

Q:Home circuit breakers and how much air is open

The air switch has an average operating life of 20000 times at rated load. In the understanding of the leakage switch,

Q:Is the zero line going through the circuit breaker?

Three-phase four-wire zero line is absolutely not allowed to go through the circuit breaker, because the zero line is broken, the line of all 220V appliances will withstand 380V line voltage and burned.
