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.
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.
Fire Resistance Testing enclosures
PH120
Insulation integrity (120-minute exposure) in accordance with BS EN 50200 & BS 8434-2 (>9300 C) with exposure to fire with water spray & mechanical shock. Rated voltage 600V rms.
IEC 331
Insulation integrity (180-minute exposure) in accordance with IEC (>7500 C) with exposure to fire with water spray & mechanical shock. Electrical system fully functional before, during and after test.

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.
