Technical description: Automatic circuit breakers A3711P for nominal current up to 160 A and VA3711P nom. current up to 200A with semiconductor, thermal and electromagnetic trips. Automatic switches A3711, ВА3711, ВА3713, ВА3715, ВА3717, А3713, А3715, А3717-2х pole are made on constant and variable (Hz 50, 400) currents. Automatic switches A3712, VA3712, VA3714, VA3716, VA3718, A3714, A3716, A3718-3x pole, are manufactured for alternating current (Hz 50, 400).

Automatic circuit breakers are designed for conducting the current in the normal mode and for protection during overloads of inadmissible duration, with short circuits and inadmissible voltage reductions, as well as for unexpected, up to 30 times a day, operative trips of electrical circuits with a nominal voltage up to 660 V AC of frequency 50 and 60 Hz and up to 440 VDC. AC circuit breakers can also be used for protection and emergency direct induction of asynchronous motors in the category of use of AC-3. The circuit-breakers are manufactured with semiconductor breakers, with semiconductor and electromagnetic maximum release, with thermal and electromagnetic maximum current trips, only with electromagnetic maximum trips of current and without the maximum release of current. The circuit-breakers can be equipped with a zero-voltage relay, an independent relay, free contacts and an electromagnetic actuator. The automatic switches are made in a stationary version - front, back and combined joints and in a sliding version.
