The Wöhner 33635 is a heavy-duty NH in-line fuse switch-disconnector designed for safe switching, dependable electrical isolation and reliable overcurrent protection in industrial low-voltage power distribution systems. Part of the Wöhner QUADRON® 185Power Speed series, this NH size 3 device features a top M12 screw connection, making it ideal for industrial switchboards, motor control centres and OEM panel-building applications where top cable entry is preferred.
The switch-disconnector incorporates an operator-independent snap-action switching mechanism with a double-breaking contact system, providing fast and consistent switching regardless of operating speed. When the cover is open, all touchable parts remain voltage-free, enhancing operator safety during inspection and maintenance.
Designed for installation on 30, 40, 60, 80, 100 and 120 × 10 mm busbars, the Wöhner 33635 forms part of the modular 185Power busbar system. It requires the appropriate mounting accessories and offers a lockable, sealable operating cover for improved safety and security.
The Wöhner 33635 combines safe switching, dependable isolation and high-capacity fuse protection within one robust industrial assembly. When fitted with suitable NH size 3 fuse links, it protects electrical installations against overloads and short circuits while providing a reliable means of isolating power during maintenance and servicing.
Its top-entry M12 connection simplifies installation where upper cable routing is preferred, while the snap-action mechanism, touch-safe construction and lockable cover make it an ideal choice for modern industrial switchgear requiring high levels of operational safety and reliability.
