CIRCUIT BREAKER

The circuit breakers is an overcurrent protection device in the electrical installation. The circuit breakers protect pipelines from damage due to strong warming in a row to high current. Circuit breakers are not reusable, not automatically back putting types of security elements. As a backup or a performance, he can switch the circuit not only overload, but also to a short circuit shut down automatically. One must then hand him over again.

The stop can be triggered by following types:

The trigger for overload:

If the preset value of the circuit breakers flowing stream significantly longer time is exceeded, the shutdown. The time to initiation depends on the strength of the current. There is a so-called trigger bimetal used, which when heated by the flowing stream and is bendable result of the stop triggers.

The manual trigger:

For repairs or arrangements with respect to maintenance or on the temporary closure may circuits on circuit breakers turned off manually. This is a rocker switch on the front side.

The electromagnetic trigger at short circuit:

If in a system short-circuit, will be shut within seconds by a power through the electromagnet system.
