 Functionality:

Electrical scheme of circuit breaker provides:

- switching and protection of DC circuits;

- warning lights while circuit breaker on.

Construction:

Automatic circuit breaker VAP-I-50 ÷ 250 does not require an additional ground during operation because of the, which is made of insulating material.

Circuit breaker’s VAP-I-500 body is a rectangular welded steel construction made of steel sheat of 2 mm thickness.  Circuit breaker’s shell painted in polymer paint RAL 7032, which is stable in time to the effects of rain and UV rays. Upon request, this circuit breaker is equipped with metal slides.

Circuit breaker VAP-I-50÷250 formed in the shell, consisting of the insulating body, cover and cable entry devices fabricated by low-pressure casting of a dielectric material.

Input and output devices for power circuits allow connection and seal flexible and armored cable with dry butchering. Construction provides control cable input device for control circuits, allowing the connection and seal of flexible cable only.
