The ABB XRG1-50/5-3P-EFM (1SEP204481R1501) is an advanced three-pole switch disconnector fuse featuring factory-fitted Electronic Fuse Monitoring (EFM) for enhanced protection and system reliability. Part of the premium ABB SlimLine XR Gold series, it is engineered for low voltage power distribution systems where continuous monitoring of fuse status helps minimise downtime and improve maintenance efficiency.
Designed for installation on 50 mm busbar systems with a 5 mm busbar thickness, the XRG1-50/5-3P-EFM offers fast, wire-free installation while maintaining a compact footprint within switchboards. The integrated Electronic Fuse Monitoring system provides rapid indication of blown fuse conditions, allowing maintenance personnel to identify faults quickly and reduce unnecessary troubleshooting.
With a 250 A rated operational current, compatibility with NH1 DIN fuse links and operation up to 690 V AC, this switch disconnector fuse is ideal for industrial switchboards, renewable energy installations, manufacturing facilities and commercial power distribution systems requiring dependable circuit protection and enhanced operational visibility.
Electronic Fuse Monitoring continuously supervises the condition of installed fuse links and provides rapid indication if a fuse operates. This allows maintenance teams to locate faults more quickly, minimise equipment downtime and improve overall system availability compared with conventional fuse switch disconnectors.
The ABB SlimLine XR Gold range has been developed for high-performance industrial and renewable energy applications where reliability, safety and ease of maintenance are essential. Its robust construction and compact busbar-mounted design make it suitable for modern electrical distribution systems.
