Description
Boxes of the series – SA, SAX and SAP are explosion-proof equipment and comply with the requirements of Directive 2014/34/EU, EN 60079-0:2012/A11:2013 have type of protection “e” according to EN IEC 60079-7:2015/A1:2018 and “t” according to EN 60079-31:2014, are intended for the installation of electrical equipment in places with a risk of explosive atmosphere. Boxes can have various configuration options, providing reliable protection for built-in explosion-proof devices, terminals, devices, wires, etc. from external influence. All devices installed must be certified according to Directive 2014/34/EU. The presented enclosures are the best solution for the subsequent assembly of finished equipment. Cable entries and drainage devices can be located on the outer surface of the housing.
Explosion-proof boxes differ in case design, overall dimensions, case material.
The equipment mounted on the basis of the presented explosion-proof enclosures allows it to be classified as electrical equipment of groups I, II and III, belongs to the category M 2 (mine version), 2 G (gas environments) and 2 D (field environments). Equipment can be placed in zones 2, 3, 21 and 22. The environment may contain explosive mixtures of gases and vapors with air of category IIA, IIB and IIC, as well as IIIA (combustible flying particles), IIIB (non-conductive dust) and IIIC (conductive dust).
The housings are made of the following materials: SA – copper-free aluminum alloy, SAX – stainless steel and SAP – polyamide. According to the manufacturing technology, the boxes are divided into cast and welded.
Boxes correspond to the following temperature classes: T6, T5, T4. When choosing a temperature class, one should take into account the power dissipation of the box body, the operating temperature and the equipment used as accessories.
When safe cable routing and termination is required in explosive atmospheres, Autonex offers the industry-leading SC/SI/SL/ST/SX and SZX series of Ex d flameproof junction boxes for projects across Qatar and the GCC. Manufactured to IEC 60079-1 and conforming to ATEX Directive 2014/34/EU, these junction boxes are available in cast and welded construction in copper-free aluminum alloy and stainless steel. Suitable for Zone 2 and Zone 3 gas environments as well as Zone 21 and Zone 22 dust environments, they serve oil and gas, petrochemical, offshore, and water treatment facilities where reliable cable disconnection and distribution must be guaranteed without compromising explosion protection integrity.
