Product description

OJON -type disconnectors

Compact dimensions, direct current paths, double-knife construction and cast resin insulators are common to all OJON -type disconnectors.

Ratings
Rated voltage (kV) 1 - 24

Normal current (A) 630 - 4000


The high short-circuit strength of these disconnectors is a result of these features. 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 - 4000 A.
The disconnectors may be connected to copper or aluminium busbars.
