Why Choose the Mersen HDF400T Direct-Mount Butterfly Handle?
The Mersen HDF400T is a robust direct-mount butterfly operating handle designed for use with compatible Mersen SF 400 A fusible disconnect switches. It provides a practical manual interface for operating the connected switch in industrial control panels, switchboards and electrical power distribution equipment.
Manufactured as part of Mersen’s low-voltage disconnect switch accessory range, the HDF400T mounts directly onto the compatible switch operating mechanism. Its butterfly-style design provides a secure grip for positive local operation, while the direct-mount arrangement offers a compact alternative to an extended shaft and separate enclosure-mounted handle.
The HDF400T is suitable for new switchgear assemblies, industrial machinery, OEM panel-building projects and replacement applications. Correct compatibility with the selected Mersen SF 400 A disconnect switch and installation arrangement should always be confirmed before fitting.

Reliable Operation of Fusible Disconnect Switches
Fusible disconnect switches combine electrical isolation with fuse-based overcurrent protection. A correctly selected operating handle provides a controlled and repeatable means of moving the switch between its operating positions while keeping the operator separated from the internal switching components.
The direct-mount configuration of the Mersen HDF400T is intended for applications where the compatible disconnect switch is operated locally from the front of its mechanism. When correctly matched with a Mersen SF 400 A switch, it provides dependable manual operation for demanding industrial electrical systems.
Typical Applications
- Industrial power distribution switchboards.
- Electrical control panels.
- Motor control centres.
- Industrial machinery isolation.
- Manufacturing and processing equipment.
- OEM switchgear and panel assemblies.
- Replacement of compatible disconnect switch handles.
