Why Choose the Mersen SA105 Selector Handle Shaft?

The Mersen SA105 is a precision-engineered selector handle shaft designed for compatible Mersen low voltage disconnect switch operating handles. Measuring 6 × 6 × 105 mm, it provides the mechanical connection between the switch mechanism and the external enclosure handle.

Designed for industrial control panels, machinery and electrical distribution equipment, the SA105 allows a disconnect switch to be operated safely from outside the enclosure. Its square-profile construction provides positive engagement with compatible handles and switch mechanisms, supporting dependable switching and isolation.

The 105 mm shaft length makes this accessory suitable for installations requiring a compact operating depth. It is supplied as a shaft only and must be selected with a compatible Mersen disconnect switch and operating handle.
