The Wöhner 33719 is a compact 160 A NH fuse switch-disconnector designed for safe switching, dependable isolation and reliable overcurrent protection in industrial low-voltage power distribution systems. As part of the Wöhner QUADRON® 185Power range, this flat version features a single-pole switchable design, making it ideal for installations requiring individual phase isolation while maintaining a low installation profile.
Designed for installation on 185 mm busbar systems, the Wöhner 33719 fits busbars measuring 30, 40, 60, 80, 100 or 120 × 10 mm. It incorporates robust M8 screw terminals, a lockable cover and self-closing inspection holes, providing improved operator safety and easier servicing.
Compatible with NH 000 and NH 00 fuse links manufactured to IEC / HD 60269-2, the 33719 is ideal for industrial switchboards, OEM machinery, motor feeders and commercial power distribution panels. Its modular QUADRON® 185Power design integrates seamlessly with other Wöhner switching and protection devices.
The Wöhner 33719 combines manual switching with NH fuse protection in a low-profile flat design, making it ideal where installation space is limited. The single-pole switching mechanism enables individual phase isolation, while the lockable cover and inspection windows enhance operational safety and maintenance efficiency.
As part of the modular QUADRON® 185Power platform, the 33719 can be combined with fuse blocks, MCCB adapters, switch-disconnectors and monitoring accessories on the same 185 mm busbar system, providing a flexible and scalable power distribution solution.
