IntelliRupter® PulseCloser® Fault Interrupter

Distribution faults damage your equipment, reliability, and bottom line. In fact, your current fault-management strategy may cause more damage than you realize by multiplying the force applied to your system when testing the line for faults after an event.

S&C’s IntelliRupter PulseCloser Fault Interrupter uses PulseClosing^® Technology todramatically reduce the amount of force used during fault testing and to significantly lessen momentary outages for customers on the main feeder. This strategy improves reliability and reduces costs for you and your customers.The IntelliRupter fault interrupter’s accurate sensing and directional capabilities will help with the increase of distributed energy installations, while PulseClosing® Technology solves the problem of stress caused by conventional reclosing.

Key Constructional & Operational Details:

IntelliRupter fault interrupters are factory-assembled on a stainless-steel base and include:

Unique magnetic latching actuators for the interrupters, providing single-phase tripping/single-phase lockout, single phase tripping/three-phase lockout, or three-phase tripping/ three-phase lockout (The interrupters can be manually tripped by means of a manual lever. Operable from the ground with an extend stick (overhead models), or they can be manually tripped by means of a manual OPEN/CLOSE/ READY lever (pad mount models)
High-accuracy sensors, for three-phase monitoring of line current and three-phase monitoring of line voltage on both sides of the interrupters (Sensing accuracy is ±0.5% for both voltage and current. Total system accuracy for fault detection, including sensing, control, and interrupting time, is ±2%.)
External power supply connector, permitting pre-installation uploading and downloading of configuration settings, plus radio programming and battery charging, as applicable, indoors in your service center or lab
Unique multi-function status indicator, which shows that the control group is operating normally (The blink rate changes when a Wi-Fi connection is made, control power is lost, or the position of the OPEN/CLOSE/READY lever is changed. A separate HOT LINE TAG indicator shows a “set” tag.)

Integrated Global Positioning System, providing 1-ms accurate time-stamping of events to speed post-event analysis as well as IntelliRupter fault interrupter location data for entry into your graphical information system.
