 Technical description: Selective circuit breakers А3793С, ВА3793С are designed for carrying out current in normal mode, for selective protection in case of short circuits, for protection during overloads 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 A 3793С are produced in stationary and in retractable versions. Switches A-3793C can be equipped with an independent release, a zero voltage release, free contacts, an electromagnetic drive, a manual remote drive (in retractable version).
