Stainless steel junction boxes type KSRV-N (KSRV-S, SA/SS)

Explosion-proof stainless steel junction boxes type KSRV-N (KSRV-S, SA/SS)

PURPOSE AND SCOPE OF APPLICATION

Explosion-proof boxes series KSRV-N are referred to stationary multi-functional devices. Boxes series KSRV-N can be used for solution of a wide range of tasks: as terminal boxes, boxes for power terminals, enclosures for installation of various Ex-components, as well as enclosures for local control stations and control cabinets in case of their installation in hazardous areas and in conditions with aggressive environment.

Explosion protection of the boxes series KSRV-N 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).

Mining version of KSRV boxes allows using them in mines hazardous with gas (methane), coal dust, as well as at underground military facilities.

Explosion-proof terminal boxes KSRV-N are rectangular enclosures with cover made of 1.2 mm sheet stainless steel grade 08X18H10 as per GOST5632-2014 (AISI 304). This type of stainless steel is frequently applied at chemical and food facilities.

All covers of explosion-proof boxes KSRV-N, except for KSRV-N111109 and KSRV-N171109 have hinges by default. Application of hinged covers increases convenience of box installation, cable and wire connection and further maintenance.

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.

Boxes series KSRV-N 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 particularly noted.

Enclosures of non-standard sizes could be made to order. Required dimension types of enclosures KSRV-N are manufactured individually if it is possible technically. Maximum dimension types of enclosures KSRV-N (TR CU certificate): 1000х1200х400 mm.
