| 11. Fuse switches, types ΒΟ-1; ΒΟ-2; ΒΟ-4 |
|
Fuse switches are intended for switching electric circuits with the rated voltage up to 380 VAC, frequency 50 Hz.
Switches are mounted in panels (cabinets) of electric energy distribution devices with the voltage up to 1000 V and ensure protection of electric lines and electricity consumers against short-circuit currents and overloads. Fuses ΟΝ-2 used in fuse switches are in conformity with GOST 7242 and Specs 16.522.113.
