Why Choose the ABB EMMU25 Metallic M25 Locking Nut?
The ABB EMMU25 is a robust metallic M25 locking nut designed for securing threaded cable entry components in electrical enclosures. Part of ABB's enclosure accessory range within the 311019-Metal Enclosed (Loadbreak) product group, it provides a secure mechanical fixing for M25 threaded installations.
The EMMU25 is specifically intended for applications where enclosure holes are not provided with threads. It allows compatible threaded cable glands and associated cable-entry fittings to be securely fastened to an enclosure, providing a simple and dependable installation solution for industrial electrical equipment.
With its M25 metric thread size and metallic construction, the EMMU25 is suitable for ABB metal-enclosed switching equipment and other compatible enclosure applications. Its compact locking-nut format makes it a practical accessory for panel building, electrical installation and industrial enclosure assembly.

Secure Cable Entry for Electrical Enclosures
Locking nuts are used to secure threaded cable-entry fittings when an electrical enclosure has a clearance hole rather than an internally threaded entry. The nut is fitted to the threaded component from inside the enclosure, providing a secure mechanical connection between the fitting and enclosure wall.
The ABB EMMU25 provides this function for M25 threaded installations. Its metallic construction makes it well suited to industrial enclosure assemblies where reliable mechanical retention and durable components are required.
Typical Applications
- Metal-enclosed electrical equipment.
- Industrial electrical enclosures and cabinets.
- Cable gland installation through unthreaded enclosure holes.
- Switch-disconnector and load-break switch enclosures.
- Control panels and industrial switchgear assemblies.
- OEM electrical panel and enclosure construction.
