£199.24
The Mersen HDF1250T is a heavy-duty direct-mount butterfly operating handle designed for compatible Mersen SF 1250 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.
Developed as part of Mersen’s low-voltage disconnect switch accessory range, the HDF1250T mounts directly onto the compatible switch. Its butterfly-style design provides a secure grip for positive manual operation, making it suitable for applications where reliable switching and electrical isolation are essential.
The HDF1250T is intended specifically for compatible 1250 A SF-series switches. Its direct-mount configuration creates a compact operating arrangement without the extended shaft used for door-coupled handles. The exact switch model and mounting arrangement should always be confirmed before installation.
Fusible disconnect switches combine circuit isolation with fuse-based overcurrent protection. A correctly selected operating handle provides a controlled means of moving the switch between its operating positions while keeping the user separated from the internal switching components.
The direct-mount design of the Mersen HDF1250T is intended for applications where the compatible switch is operated locally from the front of its mechanism. When correctly installed with an SF 1250 A disconnect switch, it provides dependable manual operation for demanding industrial power systems.
