Explosion-proof equipment plant
Explosion-proof boxes series KSRV-M are referred to stationary multi-functional devices. Boxes series KSRV-M can be used for solution of a wide range of tasks: as terminal boxes, boxes for power terminals, boxes for installation of various Ex-components, as well as enclosures for local control stations and control cabinet in case of their installation in hazardous areas and in conditions with aggressive environment.
Explosion protection of the boxes series KSRV-M is provided by following types of explosion protection: “Intrinsically safe circuit ia” as per GOST 30852.10-2002 (IEC 60079-11:1999), protection type “e” as per GOST 30852.8-2002 and their design as per requirements of GOST 30852.0-2002 (IEC 60079-0:1998). Type of explosion protection “intrinsically safe circuit” is reached by means of installation of electrotechnical devices in the boxes with incoming and outgoing intrinsically safe circuits of level “ia”. Type of explosion protection “e” is reached by means of provision of ingress protection degree at least IP65, creepage distance and clearance between clamps on terminal blocks, as well as electrical insulation materials in accordance with the requirements of GOST 30852.0-2002 (IEC 60079-0:1998).
All covers of explosion-proof boxes KSRV-M, except for KSRV-M111109 and KSRV-M171109 have hinges by default. Application of hinged covers increases convenience of box installation, cable and wire connection and further maintenance.
Explosion-proof boxes are rectangular enclosures with cover made of 1.2 mm sheet mild steel (other steel thickness upon approval). This type of steel is frequently applied at facilities with limited budget, at chemical and food facilities. Possibility of application of these products by OEM companies should be particularly noted.
Thanks to special seal protected against exposure to environment, the enclosure has excellent degree of ingress protection IP66 which is confirmed by test results. All fastening bolts of the cover are made of stainless steel and have special seals, and that guarantees ingress protection degree IP66.
Inner and outer ground clamps are made of stainless steel and can be connected to mounting rail for terminals, mounting plate or earth bus bar. Grounding for cable glands is provided through contact with the wall of enclosure with no need to apply additional measures on provision of grounding circuit continuity.
Explosion-proof boxes series KSRV-M can be supplied with various options: with installation of terminals for different current ratings, with Ex-components as per customer’s specification or empty as Ex-component required in assembly with customer’s equipment for certification. Possibility of application of these products by OEM companies should be additionally mentioned, where excellent quality of mechanical processing of aluminum come to the forefront.
Scope of application - hazardous indoor and outdoor areas in accordance with explosion protection marking, GOST 30852.13-2002 (IEC 60079-14:1996) and areas hazardous with combustible dust ignition, as per GOST IEC 61241-3-2011, dangerous production facilities of I, II, III, IV hazard classes under supervision of Rostekhnadzor and national supervisory bodies of the CU and the CIS countries.
