Relay, time relay, air switch, leakage switch, air with leakage, circuit breakers ,,, how to understand and distinguish between ah? What is the working principle and the role of decibel? The
The relay is generally used as an auxiliary control loop;
Time relay for delay or timing, the relay provides contact opening and closing;
Air switch for the need to see the rated current, breaking short-circuit current. With the ability to break short-circuit current called circuit breaker;
Leakage switch and air leakage switch the same (air as extinguished arc medium), with leakage protection.
Time relay and ordinary relay is the difference between the time relay with power or power off when the contact delay closed (or disconnect) function.
Circuit breaker and air switch is one thing, leakage switch is also a circuit breaker, but also with residual current action components, in the leakage when the circuit breaker can be opened, open with leakage circuit is also attached to the residual current action components, Generally speaking, the leakage switch is usually referred to with the leakage protection function of the micro-off, civil or public buildings used, open with leakage may refer to the larger capacity of the switch with leakage protection.
