Selective circuit breakers of type A 3714C are designed for conducting current in normal mode, for selective protection in case of short circuits, for protection during unloading of unacceptable duration and for infrequent (up to 30 times a day) operational switching-on and switching off of electrical circuits with voltage up to 380V AC frequency 50 and 60Hz.
Switches A3714BS and A3714S are manufactured in stationary and in retractable designs.
Switches can be equipped with an independent release, a zero-voltage release, free contacts, an electromagnetic drive, a manual remote drive (in retractable version).
