Fire-resistant wall box KPZ-1 KPZ-1_PO

Fire-resistant wall boxes – safety and reliability of installation

The KPZ-1 electrical installation box is designed for safe mounting in fire-resistant partitions, ensuring the integrity of the electrical installation in the event of a fire. The box's construction, made of high-quality plastic, guarantees effective protection of cables and connections, minimizing the risk of fire spreading. This is a crucial solution in buildings with increased safety requirements, such as public facilities, hospitals, or shopping centers.

Construction and application

The KPZ-1 box is intended for mounting in hollow walls made of gypsum plasterboard or cellular concrete. Its round shape and 73 mm diameter allow for easy installation and adaptation to standard openings. Equipped with four inlets and a membrane cable gland, it provides flexibility in routing cables with diameters from 7 to 20 mm and pipes with diameters of 20/25 mm. The expanding foam material located both outside and inside the box expands in the event of a fire, sealing the installation opening and blocking access to flames. This ensures that the box meets fire protection requirements, maintaining the integrity of the partition. Device mounting is done using screws – the box has appropriate threads for stable mounting.

Key features and benefits

• Fire protection: Ensures the integrity and insulation of fire-resistant partitions, delaying the spread of fire.
• Installation flexibility: Compatible with various types of walls and cables thanks to four inlets and a membrane gland.
• Tightness: Flexible inlet openings guarantee a tight passage for cables and pipes, even after their installation.
• Durable construction: Made of robust plastic resistant to mechanical damage.
• Easy installation: Triple-threaded mounting screws with metal feet enable quick and secure installation.
• Safety: Halogen-free material minimizes the emission of toxic substances in the event of a fire.
• High resistance: IP30 degree of protection protects against accidental contact and the ingress of solid objects larger than 2.5 mm.
• Weather resistance: Provides protection against the effects of weather conditions during outdoor installations (to a limited extent).
• Maximum wire cross-section: Supports wires with a cross-section of up to 4 mm², ensuring compatibility with most standard electrical installations.

The KPZ-1 box is an investment in the safety and reliability of the electrical installation, especially important in places requiring a high level of fire protection. Its solid construction and advanced properties make it an ideal choice for both professional installers and end customers who care about the safety of their property and lives.
