Introduction to Arc Quenching Switchgear
This document provides essential information regarding Eaton's Arc Quenching Magnum PXR low-voltage switchgear. It details the technology behind arc quenching, its application in substations, various layout configurations, and critical technical specifications designed to enhance safety and performance in power distribution systems.
The Arc Quenching Device (AQD), when triggered by the Eaton Arc Flash Relay (EAFR), rapidly extinguishes arcing faults, significantly reducing incident energy and improving personnel safety. This guide covers both load-side and line-side applications, enclosure options, and standards compliance.
For more detailed design information and application examples, please refer to the comprehensive library of design guides available at Eaton.com/designguides.
