£1,091.05
The ABB XRG160BS-50/5-4P (1SEP204486R1700) is a robust four-pole switch disconnector fuse designed for safe switching, electrical isolation and fuse protection in low-voltage power distribution systems. As part of the proven ABB SlimLine XR Gold series, it provides dependable performance in industrial switchboards and commercial distribution equipment.
This model is designed for installation on busbar systems with a 50 mm distance between phases and a 5 mm busbar thickness. Its busbar-mounted construction, integrated slide support and bolt-connected main terminals help simplify switchboard assembly while providing secure and reliable electrical connections.
With a rated current of 160 A, a rated operational voltage of 500 V AC and compatibility with Lawson 00T British Standard fuse links, the XRG160BS-50/5-4P is suitable for protecting four-pole feeders and distribution circuits. Its manual front operation and IP41 front protection make it a dependable solution for modern electrical installations.
Switch disconnector fuses combine manual circuit isolation with the overload and short-circuit protection provided by replaceable fuse links. The four-pole configuration enables simultaneous isolation of four conductors, making the unit suitable for distribution systems where neutral switching or complete circuit separation is required.
The ABB SlimLine XR Gold range is designed to improve installation efficiency and maximise outgoing feeder capacity within electrical switchboards. Its compact busbar-mounted format can be installed horizontally or vertically, helping panel builders create flexible and space-efficient distribution systems.
