Maintaining electrical functions E30 – E90 Body made of polycarbonate, halogen-free High degree of protection IP65 Through holes with a diameter of 8x25 and 2x20 Mounting surfaces: ceilings, cable trays Ability to work in temperature from -25 to 55 [°C] Dimensions:. Maintaining electrical functions E30 – E90 Body made of polycarbonate, halogen-free High degree of protection IP65 Through holes with a diameter of 8x25 and 2x20 Mounting surfaces: ceilings, cable trays Ability to work in temperature from -25 to 55 [°C] Dimensions:. The fireproof wiring box is designed for connecting and/or branching cables of installations which guarantee continuous operation during fire conditions. Enclosures for preventative fire protection, A2, F30/F90, I30/I90, E30/E90 Preventive fire protection is not only a matter for those constructing a building. In planning and designing their installations, expert electrical planners and engineers or switchgear manufacturers are responsible for. The junction box for fire alarm systems is designed for connecting fire protection devices in cable installation systems with fire resistance according to the DIN 4102-12 standard, where the uninterruptible power supply or transmission of the signal in case of fire is required. The junction box is. tended for use in fire alarm systems (FAS). They are part of the so-called cable assembly, whose main task is: maintaining the continuity of electricity supply or signal transmission in fire conditions for the time required to a es include, for example, signaling devices. As a result of high temp. Boxes distribute low currents in an area equipped with 1 to 12 RJ 45 sockets.
