Why Choose the Mersen HD40 Direct-Mount Disconnect Switch Handle?
The Mersen HD40 is a compact and reliable direct-mount operating handle designed for compatible Mersen UL 508 non-fused disconnect switches rated from 16 to 40 A. It provides a practical manual interface for operating the connected switch in industrial machinery, control panels and electrical distribution equipment.
Developed as part of Mersen’s low-voltage disconnect switch accessory range, the HD40 mounts directly onto the compatible switch mechanism. This direct configuration creates a compact operating arrangement and avoids the need for the extended operating shaft normally used with door-coupled handles.
The HD40 is suitable for new control panel assemblies, original equipment manufacturing and replacement applications. Its genuine Mersen construction helps ensure dependable mechanical operation and compatibility when correctly matched with the specified disconnect switch.
