Why Choose the Wöhner 33345 CAPUS® Panel Extension Shaft?
The Wöhner 33345 is an extension shaft for selected Wöhner CAPUS® Panel switch disconnectors and NH fuse switch disconnectors. It transfers the movement of a door-mounted rotary operating handle to the switching device installed inside an electrical enclosure, enabling convenient front-of-panel operation.
Designed for professional switchgear and control-panel construction, the extension shaft helps bridge the distance between the enclosure door and the panel-mounted switching mechanism. Its rigid mechanical design supports dependable torque transmission and accurate switching during normal operation.
The Wöhner 33345 is suitable for industrial installations where the switch disconnector is mounted deeper within the cabinet and cannot be connected directly to the external rotary handle. It should be used with the appropriate Wöhner door-coupling drive, operating handle and compatible CAPUS® Panel device.

Reliable Door-Coupled Switch Operation
A door-coupled operating system allows a switch disconnector mounted inside an enclosure to be controlled from the cabinet door. The extension shaft forms the mechanical link between the external operating handle and the device, transmitting the operator's movement directly to the switching mechanism.
The Wöhner 33345 is intended to support dependable alignment and torque transfer in professionally assembled switchboards. Correct installation depth, shaft alignment and accessory compatibility should be checked during panel design to ensure smooth and reliable operation.
Typical Applications
- Industrial switchboards.
- Electrical distribution panels.
- Machine control cabinets.
- Motor control centres.
- OEM switchgear assemblies.
- Industrial automation systems.
