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.
