Quick-acting circuit breakers А 3734B 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 inclusions and outages of electrical circuits with voltage up to 690 VAC frequencies of 50 and 60 Hz.
Switches A-3734B are produced in stationary and in retractable versions. Switches can be equipped with an independent release, a zero-voltage release, free contacts, an electromagnetic drive, a manual remote drive (in retractable version).
