ASCO 4000 Series Electrically Operated Bypass-Isolation Transfer Switch
The ASCO 4000 Series Electrically Operated Bypass-Isolation Transfer Switch provides high-speed load transfer between differing sources of power using a reliable, field-proven, solenoid-operated contactor and robust controls. The 4000 Series reliably transfers critical loads between differing power sources and 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.
The 4000 Series Electrically Operated Bypass Switches are available in automatic or non-automatic transfer models. Both types monitor voltage and frequency and allow transfer only when the alternate source presents acceptable characteristics. Automatic models start engine generators and transfer loads to the alternate source without human intervention. Non-automatic models require an operator to initiate these operations.
