Fire Rated GPO Box

Fire Rated GPO Box 

Every year, over half of accidental domestic fires in the INDIA are caused by electricity.  Most of these are caused by electrical products, either through misuse or faults. Electric Fire origin on account of electric short circuit, overheating, overloading, use or non standard appliances, illegal tapping of electrical wires, improper electrical wiring, carelessness and ignorance etc.

A fire rated detector junction box typically adheres to standards like BS 6387 (British Standard) which specifies testing categories for fire resistance, including "C" for fire alone, "W" for fire and water, and "Z" for fire with mechanical shock, ensuring the box maintains electrical integrity during a fire for a designated period, usually measured in minutes depending on the specific application and fire rating required.

GPO stands for general purpose outlet. GPOs mainly use as power outlets to supply power to your electronics. They are more commonly known as the power point or socket outlet. 

Maintaining fire ratings of walls even in back to back installations, Fire rated wall boxes are manufactured from robust galvabond to prevent distortion or corrosion, even under the toughest of conditions. All wall boxes should with ample knockouts for easy cable access. In addition, fixing boxes to plasterboard walls is easier than ever before thanks to clamping arms that quickly slide into place and tighten. FIRE RATED UP TO 2 HOURS.

·        We suggest Don’t overload electrical adaptors by plugging too many appliances into one socket, especially those with a high electrical current rating such as kettles, irons and heaters. Consider having additional sockets installed if you regularly rely on extension leads and adaptors - and use a registered electrician to carry out the installation work

Also follow detector mounting box/JB in same way. 96mm x 96mm box / jb is common measurement for all brand detectors. Similar as per your detection system product brand / size for Control Module, Monitor Module, MCP etc. FIRE RATED UP TO 2 HOURS.

Key points about fire rated detector junction box standards:

·        Testing Categories:

Different fire exposure scenarios are tested, including high temperature flames with or without water spray and mechanical impact. 

·        Material Requirements:

Fire rated boxes are often made from materials like high-quality steel or ceramic with special insulation properties to withstand high temperatures. 

·        Functional Integrity:

The primary concern is maintaining electrical connectivity during a fire, ensuring critical circuits like fire alarms remain operational. 

Certified according to the rigorous standards of DIN 4102-12 for classes E30, E60, E90, and tested according to IEC 60331-1, this box is designed to  maintain critical services during a fire. Made of halogen-free technopolymer and steel, junction boxes offer complete customisation with single- and double-contact ceramic terminals, ceramic fuse holders, and signal  terminal blocks. Mandatory in high-traffic areas such as schools, hospitals, public buildings, industrial plants, and shopping centres, these boxes ensure the maintenance of electrical functionality even at extreme temperatures up to 1000°C for 90 minutes and 830°C for 120 minutes.

With high IP66/IP67 protection, this junction boxes retain functionality even in outdoor environments, maintaining fire resistance specifications from class E30 to E90 according to DIN 4102-12. Versions in technopolymer and steel offer practical and safe mounting and wiring solutions, with rails and rotating plates for easy installation of power terminals, signal terminals, and fuses. The classification according to DIN 4102-12 standard, which includes "E30," "E60," and "E90" categories,  ensures that electrical circuits remain operational during a fire, while the IEC 60331-1 test guarantees a performance equivalent to class PH120 of EN 50200, which is crucial for the fire resistance of electrical cables. This junction boxes are essential for the continuity of electrical supplies during a fire, ensuring the proper operation of safety devices such as fire alarm systems and emergency lighting.

ZONE 1 HAZARDOUS AREA

Zone 1 is a classified hazardous area location in which an explosive atmosphere consisting of a mixture with air of flammable substances in the form of gas, vapour or mist is likely to occur in normal operation occasionally.

ZONE 2 HAZARDOUS AREA

Zone 2 is a classified hazardous area location in which an explosive atmosphere consisting of a mixture with air of flammable substances in the form of gas, vapour or mist is not likely to occur in normal operation but, if it does occur, persists for a short period only.

Fully ATEX certified junction boxes for hazardous area, high voltage and industrial applications can be designed and supplied customised to suit specific requirements.

Typical applications for the junction boxes include the distribution of low voltage electrical supply for power and lighting systems in onshore and offshore environments. Hazardous area junction boxes can also be configured as power supply boxes to control heat tracing systems including series heating, self-regulating and constant wattage parallel trace heating cables.
