Line-Rupter™

Introduction

S&C Line-Rupter is an in-series circuit-breaking interrupter and circuit-making and isolating disconnect, especially suited for line and cable switching; specifically load splitting (parallel or loop switching), load dropping, and line and cable dropping. Line-Rupter is capable of closing, carrying, and interrupting load currents and parallel or loop currents, as well as line- and cable-charging current.

Each pole-unit of the S&C Line-Rupter includes a brain which provides built-in positive sequence control . . . and a fully enclosed stored-energy source dedicated solely to operation of the interrupting unit which is in the circuit at all times. Close-and-trip mechanisms are fully enclosed and protected, too. There are no external linkages, lever arms, cams, shunts, etc. that must be coordinated with a disconnect blade to accomplish circuit interruption. Positively sequenced operation is assured regardless of severe weather conditions such as high winds, rain, sleet or snow.

Line-Rupters are available in three-pole vertical-break style and are intended for upright or vertical mounting on a structure, or upright mounting on S&C Mounting Pedestals, or pedestals furnished by the user. Line-Rupters include a manual operating mechanism with geared operating handle. Alternately, for remote supervisory control, power operation can be provided with an S&C Switch Operator - Type LS-2.
