INDUSTRIAL PURPOSES $] PART 2 DIMENSIONAL INTERCHANGEABILITY REQUIREMENTS +, FOR PIN AND CONTACT-TUBE ACCESSORIES (First Revision ) ICS 29.120.30 0 BIS 2002 BUREAU OF INDIAN STANDARDS MANAK BHAVAN, 9 BAHADUR SHAH ZAFAR MARG NEW DELHI 110002 December 2002 Price Group 15 b.,. , NATIONAL FOREWORD This Indian Standard (Part 2) (First Revision) which is identical with IEC 60309-2(1999) ‘Plugs, socket- outlets and couplers for industrial purposes — Part 2: Dimensional interchangeability requirements for pin and contact-tube accessories’ issued by the International Electrotechnical Commission (lEC) was adopted by the Bureau of Indian Standards on the recommendation of the Electrical Wiring Accessories Sectional Committee and approval of the Electrotechnical Division Council. This standard (Part 2) was first published in 1996. The first revision has been undertaken to bring it in line with latest version of corresponding IEC publication. The text of the IEC standard has been approved as suitable for publication as an Indian Standard without deviations. This standard shall be read in conjunction with Part 1 of this standard. In this adopted standard, certain terminology and convention are however not identical to those used in Indian Standard. Attention is particularly drawn to the following. a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’; and b) Comma (,) has been used as a decimal marker, while in Indian Standard, the current practice is to use a point (.) as the decimal marker. Only the English text of the IEC Publication has been retained while adopting it as an Indian Standard, and as such the page numbers given here are not same as in IEC Publication. For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test, shall be rounded off in accordance with IS 2:1960 ‘Rules for rounding off numerical values (revised) ’. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard. lS/lEC 60309-2:2002 IEC 60309-2 ( 1999) Page Clause 1 Scope ............................................................................................................................. 1 2 Definitions ....................................................................................................................... 1 3 Normative references ..................................................................................................... 2 4 General .......................................................................................................................... 2 5 Standard ratings ............................................................................................................. 2 6 Classification ................................................................................................................. 2 7 Marking .......................................................................................................................... 3 8 Dimensions .................................................................................................................... 6 9 Protection against electric shock .................................................................................... 11 lU Provision for earthing ..................................................................................................... 11 11 Terminals ....................................................................................................................... 11 12 Interlocks and retaining devices ...................................................................................... 15 13 Re$istancetoageing of rubber and thermoplastic matetial ............................................. 15 14 General construction ...................................................................................................... 16 15 Construction of socket-outlets ........................................................................................ 16 16 Construction of plugs and connectors ............................................................................. 18 17 Construction of appliance inlets ...................................................................................... 19 ~.- 18 Degrees of protection ..................................................................................................... 19 .: 19 Insulation resistance and dielectric strength .................................................................... 19 ;! “ 3 20 Breaking capacity ........... ............................................................................................... 20 21 Normal operation ................ .............................................................fl............................. 20 22 Temperature tise ............................................................................................................ 20 23 Flexible cables and their connection ............................................................................... 21 24 Mechanical strength ...............................l ....................................................................... 21 25 Screws, current-carrying parts and connections .............................................................. 21 26 Creepage distances, clearances and distances through sealing compound ..................... 21 27 Resistance to heat, fire and tracking ............................................................................... 21 28 Corrosion and resistance to rusting ................................................................................ 21 29 Conditional short-circuit current withstand test ................................................................ 21 30 Electromagnetic compatibility ......................................................................................... 21 Standards sheets .................................................................................................................. 22 Figures ................................................................................................................................. 55 lS/lEC 60309-2:2002 IEC 60309-2 (1999) Indian Standard PLUGS, SOCKET-OUTLETS AND COUPLERS FOR INDUSTRIAL PURPOSES PART 2 DIMENSIONAL INTERCHANGEABILITY REQUIREMENTS FOR PIN AND CONTACT-TUBE ACCESSORIES (First Revision ) 1 Scope Replacement: This standard applies to plugs and socket-outlets, cable couplers and appliance couplers with a rated operating voltage not exceeding 690 V, 500 Hz and a rated current not exceeding 125 A, primarily intended for industrial use, either indoors or outdoors. NOTE - All references for accessories with a rated current of more than 125 A in part 1 are not applicable to this part 2. This standard applies to plugs and socket-outlets, cable couplers and appliance couplers with pins and contact tubes of standardized configurations. This standard applies to plugs and socket-outlets, cable couplers and appliance couplers, hereinafter referred to as accessories, for use when the ambient temperature is normally within the range –25 ‘C to 40 “C. The use of these accessories on building sites and for agricultural, commercial and domestic applications is not precluded. Socket-outlets or appliance inlets incorporated in or fixed to electrical equipment are within the scope of this standard. This standard also applies to accessories intended to be used in extra- --- Iow voltage installations. NOTE – This standard does not apply to accessories primarily intended for domestic and similar general purposes. In locations where special conditions prevail, for example on board ship or where explosions are liable to occur, additional requirements may be necessary. 2 Definitions This clause of part 1 is applicable except as follows: Additional subclause: 2.101 phase inverter a plug or an appliance inlet with operating means to interchange the position of two phase pins without disconnecting them from the conductors lS/lEC
