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 specifi-
cation condition, the ZTSCT Model oper-
ates as a standard delayed transition
switch (ZTSD Model). 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.
