2CPX041074R9999 ABB 1/0EF11 Fire Protection Extension Frame 575 x 895 x 22 mm 90 Min

Why Choose the ABB 1/0EF11 Fire Protection Extension Frame?

The ABB 1/0EF11, order code 2CPX041074R9999, is a fire protection extension frame for single-leaf facing doors within the ABB VF enclosure system. As part of the ABB DESUJ Sub Distribution product group, it provides an additional mounting depth for compatible fire protection facing doors used in professional indoor electrical distribution installations.

The 1/0EF11 has external dimensions of 575 mm wide × 895 mm high × 22 mm deep and internal dimensions of 345 mm wide × 665 mm high × 22 mm deep. It is designed for compatible single-leaf facing doors with construction height 0 and field width 1, providing a precisely matched accessory for the corresponding ABB fire protection enclosure configuration.

The extension frame is particularly useful where an existing electrical distribution assembly projects by more than 20 mm from the wall and additional clearance is required for the facing door. Designed for the ABB 90-minute fire protection system, the 1/0EF11 is rated for 90-minute fire resistance and functional integrity and provides IP54 protection as part of the appropriate compatible installation.

Additional Clearance for ABB Fire Protection Facing Doors

An extension frame allows a compatible fire protection facing door to be installed where the existing electrical distribution assembly projects further from the wall than a standard installation permits. The ABB 1/0EF11 adds 22 mm of frame depth and is specifically matched to single-leaf facing doors in construction height 0 and field width 1.

With external dimensions of 575 × 895 × 22 mm and internal dimensions of 345 × 665 × 22 mm, the frame provides a system-coordinated solution without changing the basic fire protection door format. It is particularly applicable when an existing distribution board projects by more than 20 mm from the wall and additional clearance is required for installation of the compatible ABB facing door.

Typical Applications

• ABB fire-protected low-voltage sub-distribution systems.
• Single-leaf fire protection facing-door installations.
• Existing distribution boards projecting more than 20 mm from the wall.
• Commercial and public-building electrical distribution.
• Emergency and safety-related electrical distribution systems.
• Electrical risers and building-services distribution areas.
• Compatible ABB VF indoor fire protection installations.
