Why Choose the Mersen SA130 Selector Handle Shaft?
The Mersen SA130 is a purpose-designed selector handle shaft for compatible Mersen UL508 non-fusible disconnect switch operating systems. Featuring a 6 × 6 mm square profile and an overall length of 130 mm, it provides the mechanical link between an externally mounted operating handle and the switch mechanism installed inside an electrical enclosure.
The SA130 enables authorised personnel to operate a compatible disconnect switch from outside the control panel, supporting safe equipment isolation without opening the enclosure during normal switching. Its square shaft profile provides secure engagement with the associated handle and switch mechanism for reliable transfer of rotational movement.
With its 130 mm length, this shaft is suitable for installations where additional distance is required between the enclosure door and the internally mounted switch. It is supplied as an individual accessory and should be selected with a compatible Mersen handle and UL508 disconnect switch.

Reliable External Operation for Industrial Disconnect Switches
The Mersen SA130 transfers the rotational movement of an enclosure-mounted operating handle to a compatible disconnect switch located inside the panel. This arrangement allows machinery and electrical equipment to be switched or isolated without exposing the operator to live internal components.
When installed with the appropriate Mersen handle and switch mechanism, the shaft can form part of a door-interlocked isolation system that helps prevent the enclosure from being opened while the switch is in the ON position. Compatibility and enclosure depth should be confirmed before installation.
Typical Applications
- Industrial control panels.
- OEM machinery disconnect systems.
- Motor control equipment.
- Automation enclosures.
- Manufacturing machinery.
- Panel-mounted electrical isolation assemblies.
