Circuit breaker A3791

Sale and manufacture of automatic circuit breakers А3791BU3, А3791BT3, A3791/1BU3, А3791BR, А3791U05, А3791UO5 630A, 800A =220V, =440V DC and 380-660V 50-60Hz AC in Europe. Export.

Automatic switches А3791, ВА3791 are designed to conduct current in normal mode and for selective protection in case of short circuits, overloads of unacceptable duration and unacceptable voltage drops, as well as for infrequent (up to 30 times a day) operational tripping of electrical circuits with rated voltage up to 660 V AC current frequency of 50 and 60 Hz.

Switches A3791 are produced in a stationary version - front, rear, combined connections and in a retractable version. Switches can be equipped with an independent release, a zero-voltage release, free contacts, an electromagnetic drive, a manual remote drive (in retractable version).

Such climatic designs-

for moderate climate - A3791BU3
