Why Choose the Mersen SPA210 Pistol Handle Shaft?
The Mersen SPA210 is a durable pistol handle operating shaft designed for compatible Mersen UL 508 non-fusible disconnect switch assemblies. Featuring a 6 × 6 mm square profile and an overall length of 210 mm, it provides the mechanical connection between an enclosure-mounted pistol handle and the disconnect switch mechanism installed inside the panel.
The SPA210 enables a compatible disconnect switch to be operated safely from outside the electrical enclosure. Its square shaft construction provides secure engagement with the external handle and internal switch mechanism, supporting reliable transfer of rotational movement during switching and equipment isolation.
With its extended 210 mm shaft length, the SPA210 is suitable for deeper control panels where a greater distance separates the enclosure door from the internally mounted switch. It is designed for selected Mersen disconnect switches rated from 20 to 200 A and is supplied separately from the handle and switch.

Reliable External Operation for Industrial Disconnect Switches
The Mersen SPA210 transfers rotational movement from an externally mounted pistol handle to a compatible disconnect switch located inside an electrical enclosure. This allows machinery and electrical equipment to be switched or isolated without opening the panel during normal operation.
When installed with the appropriate Mersen handle and switch mechanism, the shaft forms part of an interlocking arrangement designed to help prevent the enclosure door from opening while the switch remains in the ON position. Its 210 mm length accommodates deeper panels and flexible internal switch mounting positions.
Typical Applications
- Industrial control panels.
- Deep machinery enclosures.
- OEM equipment disconnect assemblies.
- Motor isolation systems.
- Automation and manufacturing equipment.
- Panel-mounted UL 508 disconnect switches.
