BYPASS ISOLATION DELAYED TRANSITION SERIES AUTOMATIC TRANSFER
SWITCH |
|
Description
The ZBTSD Series
incorporates the features of the ZBTS Bypass-Isolation Switch
with those of the ZTSD unit for transfer of large motor loads,
transformers, uninterruptible power supplies (UPS) systems or
load shedding to a neutral "off" position.
In critical systems
such as those of hospitals and airports, power cannot be
interrupted for maintenance and testing of automatic transfer
switches (ATSs).
In such circumstances,
a bypass-isolation switch is essential and often required by
code. The GE Zenith Controls ZBTSD Series Delayed Transition
Transfer/Bypass-Isolation Switch meets requirements for
inspection and/or maintenance of the delayed transition
transfer switch without power interruption.
The ZBTSD 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, consisting 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.
