£161.50
The Wöhner 33704 is a compact and dependable 160 A NH fuse switch-disconnector designed for reliable switching, isolation and overcurrent protection in industrial low voltage power distribution systems. As part of the proven Wöhner QUADRON® 185Power range, this size NH 00 device features a three-pole switchable mechanism in a space-saving flat version, making it ideal for modern switchboards and control panels.
Designed for direct installation onto 185 mm busbar systems, the Wöhner 33704 is compatible with busbars measuring 30, 40, 60, 80, 100 or 120 × 10 mm. The flat construction reduces installation depth while maintaining excellent accessibility for cable termination and maintenance. Self-closing inspection holes and a lockable cover further enhance operational safety.
Supporting both NH 000 and NH 00 fuse links, the Wöhner 33704 provides dependable circuit protection for feeders, motor circuits and industrial distribution systems. Its modular design integrates seamlessly with other QUADRON® 185Power components, allowing flexible and efficient panel construction.
The Wöhner 33704 combines manual switching with NH fuse protection, allowing engineers to safely isolate electrical circuits while protecting downstream equipment against overloads and short circuits. The compact flat version is particularly suited to installations where panel depth is limited without compromising accessibility or safety.
As part of the modular QUADRON® 185Power platform, the device can be combined with other switching devices and accessories on the same busbar system, providing flexibility for new installations and future expansion.
