Why Choose the Wöhner 33641 NH In-Line Fuse Switch-Disconnector?
The Wöhner 33641 is a heavy-duty NH in-line fuse switch-disconnector engineered for safe switching, dependable electrical isolation and reliable overcurrent protection in industrial low-voltage power distribution systems. As part of the Wöhner QUADRON® 185Power Speed series, this NH size 3 device features integrated fuse monitoring together with a top M12 screw connection, making it ideal for industrial switchboards, motor control centres and OEM panel-building applications requiring upper cable entry and rapid fault indication.
The switch-disconnector incorporates an operator-independent snap-action switching mechanism with a double-breaking contact system, ensuring fast and consistent switching regardless of operating speed. Integrated fuse monitoring enables maintenance personnel to identify blown fuse links quickly, helping minimise downtime and improve operational efficiency.
Designed for installation on 30, 40, 60, 80, 100 and 120 × 10 mm busbars, the Wöhner 33641 features a touch-safe construction when open, a lockable and sealable operating cover and compatibility with the modular 185Power busbar system.
