Why Choose the ABB XRG1-50/5-3P Switch Disconnector Fuse?
The ABB XRG1-50/5-3P (1SEP204481R1500) is a high-performance three-pole switch disconnector fuse designed for safe switching, isolation and circuit protection in low-voltage electrical distribution systems. As part of the advanced ABB SlimLine XR Gold series, it combines dependable operation with a compact busbar-mounted design for demanding industrial and commercial installations.
This switch disconnector fuse is engineered for installation on busbar systems with a 50 mm phase distance and 5 mm busbar thickness. Its wire-free mounting arrangement helps reduce installation time, simplify switchboard construction and provide an efficient connection to the distribution busbar system.
With a rated operational current of 250 A, a rated operational voltage of 690 V AC and compatibility with NH1 DIN fuse links, the XRG1-50/5-3P is suitable for protecting feeders, machinery and electrical distribution circuits. Its manual operating mechanism and true-position indication support reliable isolation and improved operator safety.
