Why Choose the Wöhner 33514 QUADRON® 60Classic Speed Fuse Switch-Disconnector?
The Wöhner 33514 is a high-performance three-pole NH size 1 fuse switch-disconnector designed for safe switching, reliable isolation and overcurrent protection in demanding industrial low-voltage power distribution systems. As part of the QUADRON® 60Classic Speed range, it is equipped with top M10 cable connections and is specifically designed for operation using a door coupling rotary handle, allowing secure switching from outside the enclosure while maintaining maximum operator safety.
The switch-disconnector incorporates an operator-independent snap-action switching mechanism with double-breaking main contacts, ensuring fast and consistent switching performance regardless of handle speed. The double-breaking design also enables safe, tool-free fuse replacement while providing an additional visible isolation gap when the cover and fuse carriers are removed for maintenance.
Designed for NH size 1 fuse links, the Wöhner 33514 has a 250 A rated current and operates at up to 690 V AC. It mounts directly onto compatible Wöhner 60Classic busbar systems using CrossLink® adapter technology, making it ideal for industrial switchboards, motor control centres, OEM machinery and main power distribution equipment.
