ASCO 7000 Series Medium Voltage Transfer Switch

The ASCO 7000 Series Medium Voltage Transfer Switch protects medium voltage loads with maintainable and highly proven power transfer switches. The switches can be configured with protective relays and other options to meet specific project requirements. The 7000 Series Medium Voltage Power Transfer Switches are available in a variety of configurations, options and transfer modes, including open, delayed, closed and soft load transitions.

An ASCO 7000 Series microprocessor-based controller (Transfer Control Center) manages breaker operation to transfer critical loads between power sources. Comprising two voltage classes, 15 kV and 5 kV, the Medium Voltage Transfer Switch may be equipped with accessories and options to meet installation requirements. Additionally, custom engineered solutions per specifications may also be accommodated.

The assemblies consist of metal-clad construction, barriered controls, removable element circuit breakers and voltage transformers for functionality at nominal amperage and voltage.
