Why Choose the Mersen SA180 Selector Handle Shaft?
The Mersen SA180 is a robust selector handle operating shaft designed for compatible Mersen low voltage disconnect switch assemblies. Featuring a 6 × 6 mm square profile and an overall length of 180 mm, it provides the mechanical connection between an enclosure-mounted selector handle and the disconnect switch mechanism inside the panel.
The SA180 allows authorised personnel to operate a compatible disconnect switch safely from outside the electrical enclosure. Its square shaft construction provides secure engagement with the handle and switch mechanism, ensuring dependable transfer of rotational movement during switching and isolation procedures.
With its extended 180 mm shaft length, the SA180 is particularly suitable for deeper electrical enclosures or installations where a greater distance is required between the panel door and the internally mounted switch. It is supplied as an individual shaft accessory and must be combined with a compatible Mersen switch and operating handle.
Key Advantages
- Purpose-designed operating shaft for Mersen disconnect switches.
- 6 × 6 mm square profile for positive mechanical engagement.
- 180 mm overall length for deeper panel enclosures.
- Enables external operation of an internally mounted disconnect switch.
- Supports compatible door-interlocked isolation arrangements.
- Industrial-grade construction for reliable long-term operation.

Reliable External Operation for Disconnect Switches
The Mersen SA180 transfers rotational movement from an externally mounted selector 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 correct Mersen handle and switch mechanism, the shaft can contribute to a door-interlocking arrangement that helps prevent access to the enclosure while the switch remains in the ON position. Its 180 mm length accommodates deeper panels and flexible switch mounting positions.
Typical Applications
- Industrial control panels.
- Deep electrical enclosures.
- OEM machinery disconnect systems.
- Motor control equipment.
- Automation and manufacturing machinery.
- Panel-mounted electrical isolation assemblies.
