New automatic switches with a ralter

To ensure the protection of the electric circuit in electrical installations from the current exceeding, the automatic circuit breakers are used to disconnect the circuit, when overload or short circuit. Most often there are automatic switches that work with 2 remotely spatially from each other by the release.

Thermal type release is always located in the key chain. With the transition resistances of most compounds, there are losses of electric energy, which have a significant impact on energy loss, in general, in the automatic circuit breaker. This leads to a sudden disconnection of the circuit breaker when it is working at the nominal load.

The company KOOP has developed the design of the automatic circuit breaker. A bimetallic plate is used as a thermal release – a fixer. The element is placed in the case of the loader coil with an electromagnet.

Indirect heating of the current, which is released by the goature current. If compared with the current solutions, then it is through the thermal release that the current does not pass. That is why there is no heating of the circuit breaker, which is caused by the passage of the current through the heat release.

Since devices with a new release have the opportunity to work in the best conditions, there is no need to take into account the correction factors to the temperature regime +60.

The working point of the bimetallic plate is precisely defined, which makes it possible to maintain constant opening speed. There is also no need for labor -intensive and errors in justice work, which are needed for bimetallic type releases, which are used to the present in the designs.

CPE company produces more devices for protective shutdown, they are indicated by RCD. Use these devices in electrical installations to ensure the protection of a person from electric shock.

RCD – the main means to protect against direct touch. Used for additional protection against touching indirect. It is possible to use to create fire safety.
