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.
