4000 SERIES Electrically Operated Bypass-Isolation Transfer Switches Data Sheet
ASCO Power Transfer Switches are the most trusted critical power transfer devices in the industry. They provide high-speed load transfer between differing sources of power using a reliable, field-proven, solenoid-operated contactor and robust controls.
The new ASCO 4000 SERIES Electrically Operated Bypass-Isolation Transfer Switch provides the following features in an easy-to-deploy solution: The ASCO 4000 SERIES Bypass Isolation Transfer Switch provides the necessary capabilities and features required to reliably transfer critical loads between differing power sources. It can shunt its primary transfer mechanism at the touch of a button using a new electrical operator. This allows the switch to be isolated for testing and maintenance without interrupting power to the load. It also provides emergency transfer capability if the primary switch mechanism is disabled or removed.
