Fire-resistant junction box, for hollow walls, flush-mounted 60mm, deep, E90, black, BS117 83117007

Fire-resistant junction box for installation in cavity walls.

This deep fire-resistant junction box with a diameter of 60mm is designed to ensure the safety of electrical installations in the event of a fire. Designed for mounting in cavity walls, it is a key element of fire protection systems in buildings. Its construction and materials guarantee the continuity of the electrical circuit for at least 90 minutes (class E90), which is particularly important in places requiring a high level of protection.

Construction and operation

The box is made of halogen-free plastic, characterized by high temperature resistance. Inside there is a special element that swells in the event of a fire, tightly closing the interior of the box and cutting off the air supply. This protects the wires and connections inside from damage caused by fire and high temperature. Thanks to this, even during a fire, the electrical circuit can remain functional for a certain time, enabling, for example, evacuation or the operation of alarm systems.

Application and compliance with standards

The box has VDE certification and has been tested in accordance with DIN 4102-12. It also has European approval ETA, confirmed by tests carried out by the accredited Austrian research institute Brandschutztechnik und Sicherheitsforschung GMBH LINZ. This ensures compliance with safety requirements in force in the European Union and allows its legal use in residential, commercial and industrial buildings. It is an ideal solution for installers implementing projects requiring compliance with strict fire protection standards.

• Fire protection: Class E90 ensures the circuit remains functional for at least 90 minutes in fire conditions.
