BSS Firebox - OBO BETTERMANN

The BSS Firebox by OBO Bettermann is a high-performance fire-resistant enclosure designed for passive fire protection in electrical installations. These fireboxes are engineered to maintain circuit integrity and prevent the spread of fire through building compartments, typically rated for up to 90 or 120 minutes of fire resistance (E30, E60, E90, E120). They are constructed from robust, non-combustible materials such as mineral wool or specialized fire-resistant boards, and are available in various sizes to accommodate cable bundles, busbars, or distribution blocks. Key technical features include integrated cable entry systems with intumescent seals that expand under heat, ensuring a gas-tight and smoke-tight seal. The enclosures are designed for wall or ceiling mounting and often include pre-scored knockouts for easy cable routing. In different markets, these are also known as fire-rated cable transit boxes, firestop enclosures, or fire protection junction boxes.

These fireboxes are primarily used in commercial, industrial, and residential buildings where fire compartmentation is critical. Typical applications include cable penetrations through fire-rated walls and floors, electrical distribution rooms, data centers, and escape routes. They are essential for maintaining the fire resistance rating of building elements in accordance with standards like EN 1366-3 and UL 1479. The BSS Firebox is commonly installed in electrical rooms, mechanical shafts, and service corridors to protect critical power and control circuits.

The main subcategories within this range include the BSS 1, BSS 2, and BSS 3 series, which differ in size and cable capacity. For example, the BSS 1 is a compact unit for small cable bundles, while the BSS 3 can accommodate larger cables or multiple busbars. The article codes typically follow the pattern BSS-XXXX, where XXXX denotes the specific dimensions and fire rating. Key articles include the BSS 1-100, BSS 2-200, and BSS 3-300, each designed for specific installation requirements. These fireboxes are often supplied with mounting brackets and intumescent strips.
