MCB 1C 50A 6kA

Functions:

Protection of the electrical circuits from overload or short circuits of the outer circuit

It can be used as a device for commutation and control of electrical circuits

In combination with auxiliary devices it allows remote control,
commutation or indication of the protected circuit

For mounting in industrial buildings with high contamination level of the electric systems

For mounting at a distance from the transformer post from 150 to 850 m

Allows protection of consumers generating short circuit currents up to 6000 A
