| ZENITH ZBTS BYPASS
ISOLATION SERIES AUTOMATIC TRANSFER SWITCH |
|
Description
In critical
applications such as hospitals and airports, power cannot be
interrupted for maintenance of automatic transfer switches. In
such circumstances, a bypass-isolation switch is essential and
is often required by code.
GE Zenith Controls ZBTS
Series Bypass-Isolation Transfer Switches are the solution
when interruption of power during service or testing is not
acceptable.
Consisting of two major
modules-the Automatic Transfer and the Bypass-Isolation
Switch-the ZBTS Series incorporates the rugged construction of
all our ZTS Series switches with a quick make/quick break
manual load transfer handle and our control/interlock system,
which consists of both mechanical and electrical interlocks.
The bypass uses normal
failure sensing and a time delay to start the engine
automatically if a failure occurs when the ATS has been
removed for service-which can be done without disturbing the
load.
Features and Benefits
 |
Load is not
interrupted during bypass operation
|
|
High close-in and
withstand capacity
|
|
Temperature rise
test per UL 1008 conducted after overload and endurance
tests in unventilated enclosure-exceeds UL requirements
|
|
Available in ZBTS
(utility-generator), ZBTSU (utility-utility), ZBTSG
(generator-generator) and ZBTSM (manual) configurations;
models include standard, delayed and closed transition
|
|
Transfer switch is
located on a draw-out mechanism to facilitate maintenance
|
|
Emergency power
systems can be electrically tested without disturbing the
load
|
|
Power cables do not
have to be disconnected to remove transfer switch
|
