Switch Types

• Standard: Unless otherwise noted, the standard
switch with quick transfer will be supplied.
• Delayed Transition: When ordered as the ZTSD,
the delayed transition switch offers time delay during
transfer from one position to the other. This is primarily
for transfer of large motor or inductive loads.
Closed Transition: When ordered as the ZTSCT,
•
the closed transition switch offers two basic modes
of operation. During a failure of one source or an out
of specification condition, the
ZTSCT
as a standard delayed transition switch (
This sequence allows clear separation of an unreliable
source from an available one.
Bypass: When ordered as the ZBTS, the bypass
•
transition switch offers a draw-out mechanism, with
electrical and mechanical interlocks for secure removal
after load bypass. In this way the transfer switch
and/or the control panel may be tested, isolated and
removed for maintenance without load interruption.
