Reliable Operation of High-Current Fusible Disconnect Switches
Fusible disconnect switches combine manual 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 HDF800T is intended for installations where the compatible disconnect switch is operated locally from the front of its mechanism. When correctly matched with a Mersen SF 800 A switch, it provides dependable manual operation for high-current industrial power systems.
Typical Applications
- Industrial power distribution switchboards.
- High-current electrical isolation systems.
- Motor control centres.
- Manufacturing and processing equipment.
- Commercial and industrial distribution panels.
- OEM switchgear and panel assemblies.
- Replacement of compatible disconnect switch handles.
