Installation fireproof junction box W2 PIP-2AN through type for cable 9x4 mm²

W2 PIP-2AN through-type fireproof installation junction box is designed to route and protect electrical cables with cross-sections up to 9x4 mm² in fire-rated installations. The unit enables secure accommodation of cable transitions and splices while maintaining circuit integrity under elevated temperatures and limiting the spread of fire through wall or ceiling penetrations. The compact through-type design supports continuous cable runs and provides a sealed enclosure where fire-resistant cable management is required.

Advantages

The junction box is built for fire resistance and mechanical protection of cable splices in both residential and commercial applications. Its through-type configuration allows cables to pass through structures while preserving fire compartmentation. The product supports multiple conductors with cross-sections up to 9x4 mm² and is suitable for use where maintaining circuit integrity and reducing flame and smoke propagation are necessary. Installation is straightforward and designed to integrate with standard wiring routes.

Suitable for

• Routing and protecting multi-core power cables through walls and ceilings
• Fire-rated cable penetrations in residential and commercial buildings
• Locations requiring maintenance of circuit integrity during fire
• Protected splices and transitions in electrical distribution runs

Key specifications

• Type: through-type installation junction box for fire-rated use
• Cable capacity: supports cables up to 9x4 mm² conductor cross-section
• Function: enclosure for cable transitions, splices and protected penetrations
• Application environment: indoor wall and ceiling installations in fire-rated assemblies
• Design: compact through-pass configuration enabling continuous cable runs

How to use

Position the junction box at the planned penetration point and secure it to the structural opening following applicable electrical and fire-safety regulations. Route incoming and outgoing cables through the through passages, arrange splices or terminations inside the enclosure, and ensure proper insulation and mechanical protection of connections. Close and seal the junction box in accordance with installation requirements to maintain the intended fire-resistance performance. Verify connections and mechanical fixation before restoring wall or ceiling finishes.

Usage recommendations

Install the junction box in compliance with local electrical codes and fire-safety standards. Use appropriate cable glands, sealing materials, and approved splice methods for the conductor sizes indicated. Avoid overfilling the enclosure beyond the recommended cable capacity and confirm that installed splices and seals preserve the required fire compartmentation.
