IEC 60309-2 pdf download.Plugs, fixed or portable socket-outlets and appliance inlets for industrial purposes
1 Scope
This document applies to plugs, fixed or portable socket-outlets, and appliance inlets, hereinafter referred to as accessories, with a rated operating voltage not exceeding 1 000 V DC or 1 000 V AC with a frequency not exceeding 500 Hz and a rated current not exceeding 1 25 A, primarily intended for industrial use, either indoors or outdoors. These accessories are intended to be installed by instructed persons or skilled persons only. NOTE 1 All references for accessories with a rated current of more than 1 25 A in IEC 60309-1 are not applicable to this document. This document applies to accessories with pins and contact-tubes of standardized configurations. This document applies to 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. This document applies to accessories with screwless-type terminals or insulation piercing terminals, with a rated current up to and including 32 A for series I and 30 A for series II. Socket-outlets or appliance inlets incorporated in or fixed to electrical equipment are within the scope of this document. This document also applies to accessories intended to be used in extra-low voltage installations. NOTE 2 This document 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 can be necessary.
3 Terms and definitions
Clause 3 of IEC 60309-1 :2021 applies except as follows: Additional terms and definitions: 3.201 phase inverter plug or appliance inlet with operating means to interchange the position of two phase-pins without disconnecting them from the conductors 3.202 solid pin pin made from a single homogeneous material, without holes, slots, slits or similar outside the terminal area
4 General
Clause 4 of IEC 60309-1 :2020 applies except as follows: 4.1 Replace the fifth paragraph by the following: In this document: 2P + E covers both 2P + E and 1 P + N + E and 3P + E covers both 3P + E and 2P + N + E unless specifically excluded (see Table 208). Additional subclause: 4.201 If gauges are used, they shall be of hardened steel, all corners shall be slightly rounded- off with a maximum radius of 0,1 mm and, if not otherwise specified, the surface finish for all measurement surfaces shall be N8 minimum.
7 Marking
Clause 7 of IEC 60309-1 :2021 applies except as follows: 7.1 Replace the sentence before the compliance statement at the end of the subclause by the following paragraphs: The symbol indicating the position of the earthing contact or of the minor key or keyway shall be placed before or above the value for the rated operating voltage and separated from it by a line. These markings shall be placed after the marking for rated current, separated from it by a dash if an oblique line separates the symbol indicating the position of the earthing contact or of the minor key or keyway from the value for the rated operating voltage. If a symbol for nature of supply is used, it shall be placed after or below the marking for rated operating voltage. For three-phase accessories it is not necessary to mark the voltage phase to neutral, if any. The marking for rated current(s), position of the earthing contact or the minor key, keyway, rated operating voltage(s) and nature of supply accordingly may be as follows.For accessories having rated operating voltages exceeding 50 V, the symbol indicating the position of the earthing contact shall be a numeral followed by the letter h. The numeral is derived from the position of the earth contact tube, when compared with the face of a clock, the socket-outlet being viewed from the front with the keyway at the sixth hour. For accessories having rated operating voltages not exceeding 50 V, the symbol indicating the position of the minor key shall be a numeral followed by the letter h. The numeral is derived from the position of the minor key, when compared with the face of a clock, the socket-outlet being viewed from the front with the major key at the sixth hour. For plugs and appliance inlets, the symbol indicating the position of the earthing contact or the minor keyway shall be the same as that for the corresponding socket-outlet. Contact tubes of socket-outlets shall be positioned in the clockwise order when viewed from the front as shown in the standard sheets (see also 7.5).
