£85.15
The Mersen HD400 is a robust direct-mount operating handle designed for use with compatible Mersen low-voltage disconnect switches rated at 400 A. It provides a practical manual interface for operating the connected switch in industrial control panels, switchboards, machinery and electrical power distribution equipment.
Developed as part of Mersen’s low-voltage disconnect switch accessory range, the HD400 connects directly to the compatible switch mechanism. This compact mounting arrangement allows the switch to be operated without the extended shaft and external enclosure handle normally required for door-coupled installations.
The HD400 is suitable for new electrical panel assemblies, original equipment manufacturing and the replacement of an existing compatible handle. Its durable construction supports dependable mechanical operation in demanding industrial environments where reliable switching and electrical isolation are essential.
Disconnect switches provide a controlled method of isolating machinery, switchboards and other electrical equipment from the incoming power supply. A correctly selected operating handle allows the switch mechanism to be moved clearly and consistently between its operating positions.
The direct-mount design of the Mersen HD400 is intended for installations where the switch is operated directly from the front of its mechanism. When correctly matched with a compatible Mersen 400 A disconnect switch, it provides a compact and dependable operating solution for industrial electrical systems.
