Why Choose the Mersen HDF800T Direct-Mount Butterfly Handle?

The Mersen HDF800T is a heavy-duty direct-mount butterfly operating handle designed for use with compatible Mersen SF 800 A fusible disconnect switches. It provides a robust manual interface for operating the switch mechanism in industrial switchboards, power distribution panels and high-current electrical installations.

Manufactured as part of Mersen’s low-voltage disconnect switch accessory range, the HDF800T 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 avoids the need for an extended shaft and separate enclosure-mounted handle.

The HDF800T is suitable for new switchgear assemblies, industrial machinery, original equipment manufacturing and replacement projects. Its durable construction supports reliable mechanical operation in demanding environments where dependable switching and electrical isolation are essential.

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
