Why Choose the ABB 1/2UF2020 Fire-Protection Wall Enclosure?
The ABB 1/2UF2020 is a UF-series flush-mounted fire-protection wall enclosure designed for indoor low-voltage distribution installations. Measuring 982 × 332 × 205 mm (H × W × D), this single-field-width enclosure provides a compact solution where electrical distribution equipment requires a defined level of fire protection.
The enclosure provides 30-minute fire resistance and is manufactured from non-combustible A2-class material. It is smoke-tight and cold-smoke-tight, with fire resistance tested for 30 minutes to DIN 4102-2, fire-load insulation for 30 minutes based on DIN 4102-11 and functional integrity for 30 minutes based on DIN 4102-12.
The 1/2UF2020 provides 6 RE, 1 field width and 72 space units. It features a single right-hinged door with a 180° opening angle, top and bottom cable entry through cable bulkheads, and is prepared for compatible distribution panels, combination sets and CombiLine modules installed on an EDF mounting frame.

Reliable Fire-Protected Distribution Housing
The ABB 1/2UF2020 provides a system-based enclosure solution for electrical distribution applications where defined fire performance is required. Its non-combustible construction combines 30-minute fire resistance with smoke-tight and cold-smoke-tight characteristics, while Class II insulation and IP41 protection support professional indoor installation.
With 72 space units arranged within a single-field-width, 6 RE enclosure, the 1/2UF2020 provides substantial installation capacity while maintaining a width of only 332 mm. Preparation for ABB distribution panels, combination sets and CombiLine modules on an EDF mounting frame allows the enclosure to form the foundation of a coordinated fire-protected subdistribution assembly.
Typical Applications
- Fire-protected electrical subdistribution systems.
- Indoor flush-mounted distribution boards.
- Commercial and public-building electrical installations.
- CombiLine modular distribution assemblies.
- EDF mounting-frame installations.
- Applications requiring a non-combustible 30-minute fire-protection enclosure.
