The ABB 1SEP204488R1500, also identified as the XRG400BS-50/5-3P, is a robust three-pole switch disconnector fuse designed for reliable circuit isolation, switching and fuse protection in low-voltage electrical distribution systems. As part of the advanced ABB SlimLine XR Gold fusegear range, it is engineered for demanding industrial switchboards and power distribution applications where dependable performance and efficient use of panel space are essential.
This manually operated fused switch disconnector combines load-switching capability with effective short-circuit and overcurrent protection when fitted with compatible British Standard fuses. Its plug-in busbar connection system, integrated slide support and generous cable termination area help simplify installation, maintenance and replacement within electrical distribution assemblies.
With a rated operational current of 400 A and a rated operational voltage of up to 690 V AC, the XRG400BS-50/5-3P is suitable for high-current industrial feeders and distribution circuits. It is designed for a 50 mm phase distance and 5 mm busbar thickness, providing compatibility with appropriately configured low-voltage switchboards.
Switch disconnector fuses provide a visible and dependable method of isolating electrical circuits while incorporating fuse protection against overloads and short circuits. This makes them particularly suitable for outgoing feeders, industrial distribution boards and switchgear assemblies where safe maintenance access and reliable fault protection are required.
The ABB SlimLine XR Gold range is developed to improve switchboard efficiency through compact construction, plug-in connections and flexible mounting options. The XRG400BS-50/5-3P can support streamlined installation and servicing while maintaining dependable performance in high-current low-voltage distribution systems.
