Why Choose the Mersen SPA430 Shaft?
The Mersen SPA430 is a high-quality 6 × 6 mm pistol handle operating shaft designed for use with compatible Mersen disconnect switches and switch-fuse disconnectors. It provides a secure mechanical connection between an external rotary operating handle and the internal switch mechanism, ensuring smooth, reliable and safe operation within industrial electrical installations.
Manufactured from durable iron/zinc, the SPA430 is engineered for demanding industrial environments where dependable switch operation and long service life are essential. The shaft interlocks with the operating handle to help prevent enclosure doors from opening while the switch remains in the ON position, enhancing operator safety.
Featuring a 430 mm overall length with a 6 × 6 mm square profile, the SPA430 is ideal for deeper electrical enclosures requiring a longer operating shaft while maintaining accurate alignment between the enclosure-mounted handle and the disconnect switch.
