Specifications

ASCO power transfer switch-
es—the standard of the indus-
try—synchronize and parallel
generation and utility power,
allowing critical load transfers
without momentary outages or
surges.
Overlapping main electrical
contacts using a reliable and
field-proven solenoid
operating mechanism enable
make-before-break transfers
that help ensure continuous
power. Control logic continu-
ously monitors power source
conditions and automatically
determines whether the load
transfer should be open (con-
ventional, non-overlap mode),
or closed transition. Failure
to synchronize indication and
extended parallel time pro-
tection is built in to prevent
abnormal operation.
