Wöhner 31951 three-pole D fuse base for DIII E33 screw-in gauge ring fuse links, rated 63 A and 500 V AC/DC for mounting on 60 mm industrial busbar systems.
£24.08
The Wöhner 31951 is a robust three-pole D fuse base designed to provide reliable overcurrent protection in industrial power distribution systems. As part of the established Wöhner CUSTO® 60Classic range, it accommodates DIII (E33) screw-in gauge ring fuse links and enables efficient integration into switchboards, control panels and electrical distribution assemblies.
This fuse base features a compact, touch-protected construction that supports safe operation and straightforward fuse replacement. Its direct busbar mounting format reduces wiring requirements and installation time, making it particularly suitable for panel builders, machine manufacturers and industrial electrical engineers.
With a rated current of 63 A and a rated operating voltage of 500 V AC/DC, the Wöhner 31951 is suitable for protecting three-phase circuits in demanding industrial environments. It is designed for installation on compatible 60 mm busbar systems, providing a secure and space-efficient circuit protection solution.
D fuse bases provide a secure connection between fuse links and electrical distribution circuits. When excessive current occurs, the installed fuse link interrupts the circuit to protect cables, machinery and downstream electrical equipment from damage.
The Wöhner 31951 combines three fuse bases within a single compact assembly, making it well suited to three-phase systems. Its busbar-mounted design supports efficient panel construction while the screw-in gauge rings help ensure that correctly rated fuse links are installed.
