£2,100.14
The ABB XRG1-185/10-3P-EFM (1SEP204481R3501) is a premium three-pole switch disconnector fuse with integrated Electronic Fuse Monitoring (EFM), designed to provide safe switching, reliable isolation and intelligent fuse supervision in low voltage power distribution systems. As part of the advanced ABB SlimLine XR Gold series, it delivers enhanced operational safety while simplifying fault diagnosis in industrial and commercial installations.
Designed for installation on 185 mm busbar systems with a 10 mm busbar thickness, this switch disconnector fuse enables rapid, wire-free mounting while maintaining a compact footprint. The integrated Electronic Fuse Monitoring system provides immediate indication of blown fuse conditions, helping maintenance engineers identify faults quickly and minimise costly downtime.
With a 250 A rated operational current, 690 V AC rated operational voltage and compatibility with NH1 DIN fuse links, the XRG1-185/10-3P-EFM is ideally suited to industrial switchboards, renewable energy systems, manufacturing facilities and critical power distribution applications requiring dependable protection and intelligent monitoring.
Electronic Fuse Monitoring continuously supervises the condition of installed NH fuse links and provides rapid indication if a fuse operates. This enables maintenance personnel to locate faults more quickly, reducing downtime while improving overall system availability and maintenance efficiency.
The ABB SlimLine XR Gold range has been developed for industrial power distribution, renewable energy installations and critical infrastructure where dependable switching, intelligent monitoring and long-term reliability are essential.
