The Ferraz Shawmut Sirco and Fuserbloc Series of heavy-duty fusible and nonfusible disconnects are designed with the latest disconnect technology, make-and-break power circuits under load, and are UL, CSA, CE, and IEC rated.

The Sirco switches come in 30 to 800-A ratings. Switches up to 400 A are equipped with visible blade contacts. A defeatable piston handle automatically relatches when the panel door closes.

The Fuserblock Series break up to 200 A and use double break contacts per pole to isolate the fuse while the switch is in the off position. Fuse covers and line side shrouding are supplied to reduce or eliminate accidental contact with live, energized parts.
