STU Type Disconnect Switch

Download attachments:

The Patton & Cooke Co STU switch is a complete three phase switch assembly for use on distribution lines and circuits up to 25 kV. The ‘STU’ switch is also available in a single phase assembly. The single phase assembly is suitable for rural farming, light industrial and residential applications where a three phase switch may not be practical for either space or cost considerations.

Both three phase and single phase switches have a sturdy galvanized steel base eliminating the need for additional cross arms while offering great resistance to the elements. Available in 15/25 kV and 600/1200 A.
