Why Choose the Wöhner 31957 Busbar Mounted Fuse Holder?
The Wöhner 31957 is a compact and reliable three-pole busbar mounted fuse holder designed for 14 × 51 mm cylindrical fuse links. Developed for industrial power distribution and control applications, it provides dependable overcurrent protection while supporting efficient, space-saving panel construction.
As part of the established Wöhner 60Classic busbar system, the 31957 mounts directly onto compatible 60 mm busbars. This reduces conventional wiring requirements, simplifies installation and helps panel builders create organised electrical distribution assemblies with fewer connections.
With a rated current of 50 A and a rated operating voltage of up to 690 V AC, the Wöhner 31957 is suitable for protecting three-phase feeders, machinery circuits and industrial control equipment. Its robust construction and compact format make it ideal for switchboards, automation cabinets and OEM electrical systems.

Reliable Protection for Industrial Electrical Systems
Cylindrical fuse holders provide a secure interface between fuse links and electrical distribution circuits. When an overcurrent or short-circuit condition occurs, the correctly selected fuse link interrupts the circuit, helping protect cables, machinery and downstream components from electrical damage.
The Wöhner 31957 combines three fuse positions within one compact busbar mounted assembly. Its direct connection to the busbar system helps minimise wiring, reduces the number of connection points and supports faster assembly of industrial distribution panels.
Typical Applications
- Industrial switchboards and distribution panels.
- Three-phase power distribution systems.
- Machine building and OEM equipment.
- Motor control and automation panels.
- Industrial control cabinets.
- Electrical feeder and branch-circuit protection.
