Why Choose the Wöhner 33501 QUADRON 60Classic Speed Fuse Switch-Disconnector?
The Wöhner 33501 is a robust and highly reliable three-pole NH fuse switch-disconnector designed for safe switching, isolation and overcurrent protection in industrial low-voltage power distribution systems. As part of the advanced Wöhner QUADRON® 60Classic Speed series, it is developed for panel builders, machine manufacturers and electrical engineers requiring dependable protection with frequent switching capability.
This fuse switch-disconnector features an operator-independent snap-action switching mechanism with double-breaking main contacts. The mechanism provides consistent switching performance regardless of operating speed, while the double-break design allows safe, tool-free fuse replacement and creates an additional visible isolation gap when the cover and fuse links are removed.
With a rated current of 125 A, an operating voltage of up to 690 V AC and compatibility with NH size 000 and NH size 00 fuse links, the Wöhner 33501 is suitable for industrial feeder circuits, machinery and power distribution panels. Its top-mounted box terminal accepts copper conductors from 1.5 to 70 mm² and integrates directly with Wöhner 60Classic busbar systems.

Reliable Switching and Protection for Industrial Power Distribution
NH fuse switch-disconnectors combine fused overcurrent protection with safe load switching and electrical isolation. The Wöhner 33501 uses double-breaking main contacts and a spring-controlled switching mechanism to provide predictable, operator-independent performance in industrial electrical systems.
The device can be used as a mains disconnector in suitable applications and includes a clearly visible FLAG position indicator. Its lockable OFF position, tool-free fuse replacement and compact CrossLink® busbar mounting design help panel builders create safe, organised and maintenance-friendly distribution assemblies.
Typical Applications
- Industrial power distribution panels.
- Machine control cabinets and OEM equipment.
- Motor control centres and feeder circuits.
- Main isolation and switching applications.
- Manufacturing and process automation systems.
- Busbar-mounted industrial switchgear.
