Why Choose the ABB 4/4VF21 Fire Protection Double Door?
The ABB 4/4VF21 is a fire protection double door designed for compatible ABB electrical sub-distribution assemblies. Supplied under ABB order code 2CPX041072R9999, it provides a coordinated protective closure for installations requiring a specified 90-minute fire resistance.
The 4/4VF21 measures 1295 mm wide × 1495 mm high × 71 mm deep and uses a double-door configuration. Its four-field-width format provides broad access to compatible distribution equipment, making it suitable for larger fire-protected electrical panel installations.
Designed as part of ABB's sub-distribution system, the 4/4VF21 combines substantial enclosure coverage with a 90-minute fire protection rating. The coordinated dimensions and double-door arrangement provide panel builders and electrical contractors with a system-specific solution for protected access to compatible distribution equipment.

90-Minute Fire Protection with Wide Double-Door Access
Fire protection doors provide a protective closure for compatible electrical distribution assemblies while maintaining access to the equipment installed behind them. The ABB 4/4VF21 combines a substantial 1295 × 1495 × 71 mm format with a specified 90-minute fire protection rating, making it suitable for larger ABB sub-distribution installations.
The double-door arrangement provides practical access across the four-field-width assembly, particularly where a single wide door would be less convenient. Used with its corresponding ABB system components, the 4/4VF21 supports professionally engineered installations requiring both protected enclosure coverage and accessible electrical equipment.
Typical Applications
- Fire-protected electrical sub-distribution assemblies.
- Large electrical distribution-board installations.
- Commercial building electrical systems.
- Industrial electrical distribution panels.
- Public and institutional building distribution systems.
- Four-field-width ABB sub-distribution installations.
- Applications requiring a 90-minute fire protection double door.
