Why Choose the ABB 4/8VF21 Fire Protection Double Door?
The ABB 4/8VF21, order code 2CPX041073R9999, is a large-format 90-minute fire protection double-door assembly designed for compatible ABB low-voltage sub-distribution installations. As part of the ABB DESUJ Sub Distribution product group and VF fire protection range, it provides a coordinated protective front for demanding electrical distribution systems where enhanced fire protection is required.
The 4/8VF21 measures 1295 mm wide × 2095 mm high × 71 mm deep, providing extensive coverage for large electrical distribution assemblies. Its substantial format is suited to compatible multi-field ABB fire-protection installations where a full-height protective door arrangement is required while maintaining practical access to the electrical equipment behind the enclosure front.
Designed with a double-door configuration, the 4/8VF21 provides convenient access across its wide opening while forming part of ABB's coordinated 90-minute fire protection system. The 71 mm overall depth and large 1295 × 2095 mm format make it particularly suitable for professional commercial, industrial and building-services distribution installations.

Large-Format 90-Minute Fire Protection for ABB Distribution Systems
Large electrical distribution assemblies require protective access solutions that combine broad equipment coverage with practical servicing access. The ABB 4/8VF21 provides a substantial 1295 × 2095 mm protective front with a double-door arrangement, making it suitable for compatible large-format ABB fire-protection distribution systems.
The two-door configuration allows the wide enclosure opening to be accessed more conveniently than with a single large door, while the 71 mm overall depth integrates with the corresponding VF fire-protection system architecture. Its 90-minute fire-protection configuration makes the 4/8VF21 a specialised component for professionally engineered electrical distribution installations.
Typical Applications
- Fire-protected low-voltage sub-distribution systems.
- Large-format ABB electrical distribution assemblies.
- Commercial and public-building electrical distribution.
- Industrial electrical distribution installations.
- Emergency and safety-related electrical systems.
- Electrical risers and building-services distribution areas.
- Professional panel building and switchboard installations.
