Alduti-Rupter® Switches

Introduction

Alduti-Rupter Switch

S&C Alduti-Rupter Switches provide no-external-arc circuit interruption for overhead distribution feeders and outdoor distribution substations; they are ideally suited for the following switching duties:

  • Line switching
  • Transformer switching
  • Cable switching.

S&C Alduti-Rupter Switches are available in voltage rating through 46 kV, in seven rugged group-operated three-pole styles that can be tailored to suit any configuration and mount on any structure. They are offered in ratings of 600 amperes and 1200 amperes, continuous and interrupting. For applications where there is no need for simultaneous three-phase switching, single-pole Alduti-Rupter Switches are an excellent alternative; they’re conveniently operated with a conventional hookstick.

Because Alduti-Rupter Switches can switch loaded or unloaded lines, transformers, and cables, they are ideally suited for remote supervisory control or fully automatic operation when equipped with an S&C Switch Operator–Type AS-1A (for switches with rotating operating mechanisms) or Type AS-10 (for switches with reciprocating operating mechanisms).
