Secure Fuse Mounting for Industrial Power Systems
The Mersen Z092942 provides the mechanical support and electrical contact required to connect a compatible cylindrical fuse-link into an electrical circuit. Its contact arrangement holds the fuse securely and helps maintain a low-resistance connection during normal operation.
When the installed fuse operates following an overcurrent or short circuit, the fixed holder allows the fuse-link to be removed and replaced. The replacement fuse must match the required 20 × 127 mm dimensions, voltage rating, current rating and fuse operating class specified for the protected equipment.
Typical Applications

- Power conversion and rectifier equipment.
- Railway and traction power systems.
- Control panels and distribution assemblies.
- Industrial machinery power circuits.
- Specialist DC electrical installations.
- Equipment using 20 × 127 mm cylindrical fuse-links.
