Description
The Cooper Bussmann single pole UL modular surge arresters for 120, 240 and 347Vac single-phase systems feature local, easyID™ visual indication and optional remote contact signaling. The unique module locking system fixes the protection module to the base part. Modules can be easily replaced without tools by simply depressing the release buttons. Integrated mechanical coding between the base and protection module ensures against installing an incorrect replacement module.
• Surge arrester according to UL 1449 3rd Edition, Type 2 Component Assembly helps meet UL 508A requirements
• Heavy-duty zinc oxide varistors for high discharge capacity
• "Thermo Dynamic Control" SPD monitoring device ensures high reliability against surge events
• Module locking system with module release button makes module replacement easy without tools
• Up to 200kA Short-Circuit Current Rating (SCCR) makes higher assembly SCCR ratings possible
• Optional remote signaling of all protection modules makes status monitoring easy and accurate in any monitoring scheme
• No upstream overcurrent protection necessary to make installation easier and more economical
• Vibration and shock tested according to EN 60068-2 to withstand harsh environments
Optional Remote Signaling Contact
The remote signaling contact versions have a floating changeover contact for use as a break or make contact for easy adoption in any monitoring application.
