Wöhner 33700 QUADRON 185Power size 00 three-pole in-line fuse switch-disconnector rated at 160 A, designed for NH 000 and NH 00 fuse links on 185 mm industrial busbar systems.
£180.25
The Wöhner 33700 is a high-performance 160 A in-line fuse switch-disconnector designed for reliable protection, isolation and switching within industrial low-voltage power distribution systems. Part of the Wöhner QUADRON® 185Power range, this size 00 device combines NH fuse protection with a three-pole switching mechanism in a compact vertical format.
Engineered for installation on 185 mm busbar systems, the Wöhner 33700 is suitable for busbars measuring 30, 40, 60, 80, 100 or 120 mm wide and 10 mm thick. Its high-version housing and M8 screw connections provide a secure electrical and mechanical interface for demanding switchboard, motor control and power distribution applications.
With a rated current of 160 A, an IEC rated operational voltage of up to 800 V AC and support for NH 000 and NH 00 fuse links, the QUADRON® 33700 offers dependable circuit protection across a wide range of industrial installations. The lockable cover and self-closing inspection holes help improve operational safety and simplify testing.
In-line fuse switch-disconnectors combine the current-limiting protection of NH fuse links with a manually operated isolation function. The Wöhner 33700 allows all three phases to be disconnected together, helping engineers safely isolate equipment during servicing while protecting cables and downstream devices against overloads and short circuits.
The vertical design makes efficient use of space within switchboards, while the 185Power mounting format supports organised power distribution across high-current industrial systems. Current transformers can also be integrated into the device where monitoring or energy measurement is required.
