Mini-Rupter® Switches
For indoor distribution, 4.16 kV through 27.6 kV
Field-tested, proven, three-pole group-operated interrupter switches ideally suited for line switching, transformer switching, and cable switching duties on underground distribution circuits
S&C Mini-Rupter Switches are field-tested, proven, three-pole group-operated interrupter switches that are ideally suited for line switching, transformer switching, and cable switching duties on underground distribution circuits.
S&C Mini-Rupter Switches provide maximum operating flexibility through their exceptional fault-closing ability, which permits quick restoration of service following a fault.
Mini-Rupter Switches are available in a variety of voltage and current ratings to match the economics and switch duties of the application — from 4.16 kV through 27.6 kV nominal, 600 amperes continuous, and 400 or 600 amperes interrupting. Mini-Rupter Switches are easy to install, with their compact construction and rugged steel mounting-frame weldments. See Mini-Rupter's switch features below.
