Wöhner 33358 four-pole switch disconnector rated at 630 A for industrial switchgear, electrical isolation and low-voltage power distribution systems.
£825.54
The Wöhner 33358 is a heavy-duty 4-pole switch disconnector designed for dependable switching and safe electrical isolation within industrial power distribution systems. Developed for professional panel builders, switchgear manufacturers and OEM machine builders, it provides a practical solution for controlling high-current circuits in machinery, production equipment and low-voltage installations.
This Wöhner switch disconnector features a robust operating mechanism engineered to provide reliable switching performance and clear circuit isolation. Its four-pole configuration enables simultaneous switching of three phases and a neutral conductor, making it suitable for applications where complete multi-pole disconnection is required.
With a rated current of 630 A and a maximum operating voltage of 500 V AC, the Wöhner 33358 is suitable for use as a main switch, maintenance isolator or load-breaking device in industrial control panels. Its mounting-plate design supports straightforward integration into compatible electrical cabinets and switchgear assemblies.
Switch disconnectors provide a clearly defined method of isolating electrical equipment before inspection, servicing or maintenance. The Wöhner 33358 disconnects four conductors simultaneously, helping ensure that both phase conductors and the neutral conductor are isolated where required by the installation design.
Its high current rating makes it suitable for incoming supplies and major distribution circuits within industrial switchboards. The robust switching mechanism helps provide consistent contact operation while reducing the risk of incomplete switching caused by variations in operating speed.
