GROUND AND TEST DEVICES
These devices are supplied when ordered with
certain component variations such as Test Ports
and Interlocks. The three basic types are:
•
Simple, three or six–terminal.
•
Simple, three or six–terminal electrically
(remote) operated.
•
Complex, six-terminal, electrically (remote)
operated with manual selector switch.
These devices are basically maintenance free for
their normal operating life. Racking procedures
are similar to the standard breaker as outlined
(except that they only have a WITHDRAW AND
CONNECT position), and all detailed operational
instructions are attached to the devices.
RENEWAL PARTS
Only those renewal parts that will be required to
insure proper and timely maintenance for normal
operation of the VHK vacuum circuit breakers are
recommended to be stocked. Copies of the
applicable Renewal Parts Bulletin for specific
circuit breakers will be furnished on request from
the Component Sales Department (407-323-
8220).
The minimum quantity of assemblies and items
recommended in these bulletins are based upon
accumulated tests and operating experience.
Total assemblies are recommended for
convenient replacement, when it is necessary to
return the breaker to service as quickly as
possible. The bulletins also contain specific part
ordering instructions.
