TECHNICAL DESCRIPTION (Technical characteristics A-3711): Automatic switches of type А3711B, А-3711, А3711BHLЗ, А3711BR, А3711BTЗ, VА3711, А3711F on rated current up to 250А with electromagnetic releases. Circuit-breakers А3711, ВА3711- 2 poles are manufactured for constant and alternating currents (Hz 50, 60). Automatic switches A-3711 are designed to conduct current in normal mode and protect against short circuits and unacceptable voltage drops, as well as for infrequent, up to 30 times a day, operational tripping of electrical circuits with a rated voltage of up to 660 V AC frequency of 50 and 60 Hz and up to 440 VDC. AC automatic circuit breakers can also be used for protection and infrequent direct starts of asynchronous motors in the application category of AC-3. Automatic switches A 3711 are produced only with electromagnetic maximum current releases.

Automatic switches A-3711 are available in stationary version - front, rear and combined connection and in retractable design.

Switches A 3711 can be equipped with an independent release, a zero-voltage release, free contacts, an electromagnetic drive, a manual remote drive (in retractable version).
