Why Choose the Wöhner 33502 QUADRON Panel Speed Fuse Switch-Disconnector?
The Wöhner 33502 is a high-performance three-pole NH fuse switch-disconnector engineered for safe switching, isolation and overcurrent protection in industrial low-voltage electrical systems. As part of the advanced Wöhner QUADRON® Panel Speed series, it is designed for panel builders, OEMs and industrial electrical engineers who require dependable switching performance and reliable protection in panel-mounted installations.
The switch-disconnector incorporates an operator-independent snap-action switching mechanism with double-breaking main contacts, ensuring consistent switching regardless of handle speed. Its spring-controlled mechanism allows frequent switching while enabling safe, tool-free fuse replacement and providing a visible isolation gap when the cover and fuse carriers are removed.
Designed for NH size 000 and NH size 00 fuse links, the Wöhner 33502 has a 125 A rated current and operates on systems up to 690 V AC. The compact panel-mounted design, box terminals and multifunction operating handle make it an ideal solution for industrial switchboards, control panels and machinery.
