Why Choose the ABB 3/1EF11 Fire-Protection Extension Frame?
The ABB 3/1EF11 is a fire-protection extension frame for single-leaf facing doors, designed for compatible ABB electrical subdistribution installations. With external dimensions of 1045 × 1045 × 22 mm (H × W × D), it provides a system-specific solution for installations where the distribution assembly projects further from the finished wall surface.
Designed for overall height 1 and 3 field widths, the 3/1EF11 has internal dimensions of 815 × 815 × 22 mm. ABB specifies this additional extension frame for compatible facing-door installations where an existing distribution assembly projects by more than approximately 20 mm beyond the wall.
The 3/1EF11 belongs to ABB's fire-protection enclosure system and is associated with A2-class material and a 90-minute fire-resistance configuration. Its dedicated dimensions and single-leaf-door format make it a coordinated accessory for maintaining the required facing-door arrangement in compatible fire-protected distribution systems.

Reliable Extension for Fire-Protection Facing Doors
Correct alignment between a fire-protection facing door and the installed distribution assembly is important when the equipment projects beyond the finished wall surface. The ABB 3/1EF11 provides an additional 22 mm frame depth, allowing the corresponding single-leaf facing-door arrangement to accommodate compatible installations that extend further forward from the wall.
Its 1045 × 1045 mm external format and 815 × 815 mm internal opening are specifically configured for overall height 1 and three-field-wide ABB installations. As part of the coordinated fire-protection enclosure range, it provides a system-matched solution rather than relying on a general-purpose fabricated spacer.
Typical Applications
- ABB fire-protection electrical subdistribution installations.
- Compatible single-leaf fire-protection facing doors.
- Three-field-wide distribution-board arrangements.
- Installations where the distribution assembly projects beyond the wall.
- Commercial and public-building electrical distribution systems.
- Extension and adaptation of compatible ABB fire-protection enclosures.
