Wöhner 33338 CAPUS Panel three-pole NH size 1 fuse switch disconnector with a 250 A rated operational current for industrial low-voltage power distribution.
£590.68
The Wöhner 33338 is a robust three-pole NH fuse switch disconnector designed for dependable switching, circuit isolation and overcurrent protection in industrial low-voltage power distribution systems. As part of the established Wöhner CAPUS® Panel range, it provides a practical solution for panel builders, machine manufacturers and electrical engineers requiring reliable control of high-current circuits.
Designed for use with NH size 1 fuse links, the Wöhner 33338 combines manual switching with fuse-based protection against overloads and short circuits. Its rotary operating mechanism enables all three phases to be disconnected simultaneously, helping create a safe isolation point before inspection, maintenance or fuse replacement.
With a rated operational current of 250 A, an operating voltage of up to 690 V AC and secure screw-terminal connections, the Wöhner 33338 is well suited to industrial feeders, machinery circuits and electrical distribution panels. Its mounting-plate design supports straightforward integration into modern switchgear assemblies.
NH fuse switch disconnectors combine manual circuit isolation with the proven protection characteristics of NH fuse links. The Wöhner 33338 allows a three-phase circuit to be disconnected through a single operating mechanism while compatible fuse links protect downstream equipment against excessive current and short-circuit faults.
Its robust panel-mounted construction makes it suitable for electrical installations where dependable isolation, simple maintenance and reliable circuit protection are essential. Correctly rated fuse links, conductors and accessories should be selected according to the requirements of the installation.
