SIRCOVER are heavy-duty manual transfer switches. They ensure switching transfer of sources or transfer of two low voltage circuits on load as well as their safe disconnection.
These extremely durable switches are tested and approved for use in the most demanding applications, such as resistive load or total system applications.

Stable positions

SIRCOVER UL has three stable positions which are not affected by voltage drops or vibrations, thus protecting your load against network interference.

Compact design

The SIRCOVER UL is based on back-to-back switching technology, providing a compact solution.

On-load switching

The SIRCOVER UL enables secure and reliable switching without the need for pre-breaking upstream.
