V1 and V3 Switchgear Styles
V1 – Vacuum interruption only
Switchgear designated as V1 will only include vacuum
interruption capability. This style of switchgear does not
come equipped with visible isolation or visible grounding
capability. V1 style switchgear is available in both standard
and low profile Control front/Cable rear configurations and
double-sided configurations.

The VisoVac fault interrupter’s vacuum interrupting
mechanism utilizes proven Eaton technology which allows
for an exceptional 25 kA or 40 kA interrupting rating.
Eaton’s environment friendly medium voltage interrupters
are capable of reliably switching high-stress currents and
carrying their rated continuous current without forced
cooling.
The interrupting mechanism was designed for applications
where space is a premium such as padmount environments.
The load break mechanism is available with up-to a 900
A continuous current rating and comes with a mechanical
endurance of 10,000 operations.
The three-phase vacuum interrupter can be opened
manually or remotely via SCADA, protective relaying
or pendant. The vacuum interrupter is equipped with a
mechanical indicator and non-resettable operations counter.
Eaton vacuum interrupters are the industry standard in
quality. Please note the following:
●
Each Eaton vacuum interrupter is tested throughout the
manufacturing process and once again before packaging.
●
A dielectric withstands test and a vacuum assurance test
are performed on every interrupter.
●
Additionally, Eaton also incorporates a sequential bar
code that allows us to track material lots, as well as the
operators involved with building each interrupter in a
database.
