Why Choose the Wöhner 33620 NH In-Line Fuse Switch-Disconnector?
The Wöhner 33620 is a robust NH in-line fuse switch-disconnector designed to provide reliable switching, electrical isolation and fuse protection in industrial low-voltage power distribution systems. Part of the advanced Wöhner QUADRON® 185Power Speed series, this NH size 00 device is engineered for professional switchgear assemblies, distribution panels and busbar installations.
The device features an operator-independent snap-action mechanism that completes the switching operation consistently, regardless of how quickly the operating handle is moved. Integrated fuse monitoring helps operators identify fuse status and electrical faults, supporting faster maintenance and improved system availability.
With a rated current of 160 A and a rated operational voltage of 400 V AC, the Wöhner 33620 is suitable for demanding industrial power distribution applications. Its flat-format construction, bottom M8 connection and CrossLink interface enable efficient installation within compatible 185 mm busbar systems.
