Why Choose the Wöhner 33543 Switch Disconnector?
The Wöhner 33543 is a compact and dependable 3-pole switch disconnector designed for safe circuit isolation and frequent switching in industrial power distribution systems. Part of the established Wöhner QUADRON 60Classic Speed series, it mounts directly onto compatible 60 mm busbar systems and is suitable for switchboards, machinery panels and OEM electrical assemblies.
This switch disconnector incorporates an operator-independent spring-controlled snap-action mechanism, ensuring consistent switching performance regardless of how quickly the external handle is operated. Its double-breaking main contacts provide effective electrical isolation, while the integrated FLAG indicator gives users a clear visual indication of the switching position.
With a rated current of 160 A, a 3-pole configuration and bottom-connected box terminals, the Wöhner 33543 provides a practical solution for industrial three-phase circuits. The unit is designed for use with a door-coupling rotary handle and can be installed horizontally at 90° to the left or right while maintaining the same handle position.
