Why Choose the ABB TZ604 Middle Frame Holder?
The ABB TZ604 is a purpose-designed middle mounting frame holder for ABB TwinLine electrical enclosures. It provides a central support point when expanding compatible wall-mounted and floor-standing TwinLine cabinets with WR or EDF mounting frames or with mounting plates arranged side by side.
Manufactured from aluminium, the TZ604 has compact dimensions of 65 mm wide × 30 mm high × 45 mm deep. Its robust construction and system-specific design provide a secure connection within modular TwinLine enclosure assemblies while allowing additional mounting frame holders to be added where required by the configuration.
The TZ604 is supplied unmounted and complete with mounting bolts. It is suitable for compatible ABB TwinLine wall and floor-standing cabinets and forms part of the coordinated accessory system used to expand internal mounting structures for professional low-voltage sub-distribution installations.

Flexible TwinLine Internal Frame Expansion
ABB TwinLine mounting frame accessories enable the internal structure of compatible distribution cabinets to be adapted for different equipment arrangements. A centrally positioned holder provides additional support where WR or EDF mounting frames are expanded or where mounting plates need to be positioned next to one another.
The ABB TZ604 provides this central mounting point in a compact 65 mm × 30 mm × 45 mm aluminium component. Depending on the required cabinet expansion, additional mounting strips, frame holders or EDF adapters can be incorporated into the TwinLine installation.
Typical Applications
- ABB TwinLine wall-mounted cabinets.
- ABB TwinLine floor-standing cabinets.
- WR mounting frame expansions.
- EDF mounting frame expansions.
- Side-by-side mounting plate installations.
- Low-voltage sub-distribution cabinet configurations.
