Product Description

The vacuum circuit-breakers of type VD4 are intended for indoor installation in air-insulated switchgear systems. They have a switching capacity capable of handling the loads occurring at Start-up and shutdown of equipment and plant units both in normal and in fault state.

Vacuum circuit-breakers have particular advantages for use in networks where there is a high switching frequency in the working current range and/or where a certain number of short-circuit Breaking operations are expected. Type VD4 vacuum circuit-breakers are suitable for autoreclosing, and have exceptionally high operating reliability and long life.

The vacuum circuit-breakers of type VD4, designed in column form, can be supplied both as individual units for switchgear Type ZS1, AMS, Unigear, KYN28, etc.
