7000 series Service Entrance Power Transfer Switches
The ASCO Service Entrance Power Transfer Switch
combines automatic power switching with a discon-
nect and overcurrent protective device on the utility
source. The power transfer switch meets all National
Electric Code requirements for installation at a facil-
ity’s main utility service entrance. Service entrance
rated transfer switches generally are installed at
facilities that have a single utility feed and a single
emergency power source. A circuit breaker serves
as the utility disconnect and links are provided to
dis-connect both neutral and ground connections.
This product is either UL 1008 or UL 891 listed and is
available up to 600V and 4000A in Standard, Delayed,
Closed Transition, Soft Load, and Bypass Isolation
