Why Choose the Wöhner 33554 Switch Disconnector?
The Wöhner 33554 is a heavy-duty 3-pole switch disconnector engineered for the safe isolation and switching of high-current electrical circuits in industrial power distribution systems. As part of the proven Wöhner QUADRON 60Classic Speed range, it is designed for direct mounting onto compatible 60 mm busbar systems and is operated using a door coupling rotary handle, making it ideal for switchboards, motor control centres and OEM machinery.
The switch features an operator-independent spring-controlled snap-action mechanism that delivers fast and reliable switching regardless of handle speed. Double-breaking main contacts provide dependable electrical isolation, while the integrated FLAG position indicator offers a clear visual indication of the switch position, improving operator safety during maintenance and servicing.
With a 320 A rated current, 3-pole configuration and M10 top-connected screw terminals, the Wöhner 33554 is designed for demanding industrial applications. It can be locked in the OFF position using up to three padlocks and, when used with the appropriate red/yellow door coupling handle, is suitable as both a mains disconnector and an Emergency Off switch in accordance with IEC / EN 60204-1.
