IEC indoor disconnector OJON

OJON disconnector assures high short-circuit strength thanks to direct current paths, double-knife design and cast resin isolators, 1-24 kV, 630-6000 A.

Contact pressure is achieved by spiral springs which compress the knives.

Silver-plating prevents the contact area of the contact and knives from ageing, and keeps the temperature rise within the limits set by the standards. Owing to the double-knife construction, forces needed to operate the disconnectors remain moderate even at high rated currents.

The contacts of the disconnectors are made of copper bar for 630 A and of cast copper for 1000 - 6000 A.

The disconnectors may be connected to copper or aluminum busbars.
