Why Choose the Wöhner 33515 QUADRON® Panel Speed Fuse Switch-Disconnector?
The Wöhner 33515 is a premium three-pole NH size 1 fuse switch-disconnector engineered for dependable switching, safe isolation and overcurrent protection in industrial low-voltage power distribution systems. Part of the QUADRON® Panel Speed range, it is designed for mounting plate installation and operation via a door coupling rotary handle, allowing safe external switching without opening the enclosure.
The switch incorporates an operator-independent snap-action switching mechanism with double-breaking main contacts, ensuring fast, consistent switching performance regardless of handle speed. The double-breaking design enables safe, tool-free fuse replacement while providing an additional visible isolation gap when the cover and fuse carriers are removed.
Designed for NH size 1 fuse links, the Wöhner 33515 has a 250 A rated current and operates at up to 690 V AC. Its robust M10 screw terminals provide secure cable termination, making it an excellent solution for industrial switchboards, OEM machinery, motor control centres and main power distribution panels.
