Why Choose the ABB KF55140 Fire-Protection Terminal Box?
The ABB KF55140 is a KF-series fire-protection terminal box designed as an empty enclosure for indoor electrical installations. Measuring 550 × 550 × 128 mm (H × W × D), it provides a protected housing for terminal and connection applications where defined fire performance is required.
The KF55140 is manufactured from A2-class non-combustible material and provides 30-minute fire resistance. It is smoke-tight and provides 30-minute fire-load insulation and functional integrity within the corresponding ABB fire-protection system. The enclosure also provides IP41 protection and Class II protective insulation.
Internally, the KF55140 provides dimensions of 400 × 400 × 84 mm. It has two cable-entry areas measuring 50 × 370 mm, while the enclosure format corresponds to 3 RE, 2 field widths and 72 space units. The product is supplied as an empty terminal box without a terminal block, allowing the internal connection arrangement to be configured for the application.
