191 FOREWORD
192 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
193 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
194 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
195 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
196 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
197 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
198 in the subject dealt with may participate in this preparatory work. International, governmental and non-
199 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
200 with the International Organization for Standardization (ISO) in accordance with conditions determined by
201 agreement between the two organizations.
202 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
203 consensus of opinion on the relevant subjects since each technical committee has representation from all
204 interested IEC National Committees.
205 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
206 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
207 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
208 misinterpretation by any end user.
209 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
210 transparently to the maximum extent possible in their national and regional publications. Any divergence
211 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
212 the latter.
213 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
214 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
215 services carried out by independent certification bodies.
216 6) All users should ensure that they have the latest edition of this publication.
217 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
218 members of its technical committees and IEC National Committees for any personal injury, property damage or
219 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
220 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
221 Publications.
222 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
223 indispensable for the correct application of this publication.
224 9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
225 patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
226 respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s),
227 which may be required to implement this document. However, implementers are cautioned that this may not
228 represent the latest information, which may be obtained from the patent database available at
229 https://patents.iec.ch. IEC shall not be held responsible for identifying any or all such patent rights.
230 International Standard IEC 61076-2-111 has been prepared by subcommittee 48B: Electrical
231 connectors, of IEC technical committee 48: Electrical connectors and mechanical structures
232 for electrical and electronic equipment.
233 This International Standard cancel and replaces the first edition of IEC 61076-2-111 (2017).
234 This edition constitutes a technical revision.
235 This edition includes the following significant technical changes with respect to the previous
236 edition:
237 a) The structure of this document has been adapted to the new IEC template for standards.
238 New subclauses have been added. In Clauses 5 Dimensional information and 6
239 Characteristics, technical specifications have been updated.
240 b) This document no longer includes the mating faces for M12 E-coded connectors.

270 Detail specification for power connectors with M12 screw-locking
272 1 Scope
273 This part of IEC 61076-2 describes 4- to 6-way circular connectors with M12 screw-locking
274 with current ratings up to 16A rated current per contact and voltage ratings of 63 V or 630 V,
275 that are typically used for power supply and power applications in industrial premises.
276 These connectors consist of both, fixed and free connectors either rewirable or non-rewirable.
277 Male connectors have round contacts Ø1,0mm and Ø1,5mm.
278 The different codings provided by this document prevent the mating of differently coded male
279 or female connectors to any other similarly sized interfaces, covered by other standards and
280 the cross-mating between the different codings provided by this document.
281 NOTE M12 is the dimension of the thread of the screw locking mechanism of these circular connectors.

407 interface.
409 4 Technical information
410 4.1 Recommended methods of termination for rewirable connectors
411 The contact termination for rewirable connectors shall be of the following types: screw, crimp,
412 spring clamp, insulation piercing, insulation displacement, press-in connections according to
413 the respective part of IEC 60352 series and IEC 60999-1.
414 4.2 Connector coding, number of contacts, ratings and characteristics
415 Table 1 provides the coding of these connectors as a function of their polarity (maximum
416 number of ways and their function), number of contacts, rated voltage and rated current.

NOTE 1 – The rated current refers to the interface. It does not take into account the contact termination nor the
terminated conductor cross-section.
NOTE 2 – 4-way connectors have the same mating interface of 5-way connectors except they are void of a FE
contact.
420 Insulation resistance: 10 Ω min.
421 Contact spacing:  see interface dimensions 5.4
422 4.3 Systems of levels
423 4.3.1 Performance level
424 Connectors according to this standard are classified by mating performance level (MPL). See
425 6.5.1 for details.
426 4.3.2 Compatibility levels, according to IEC 61076-1
427 Connectors according to this standard are intermateable and interoperable according to IEC
428 61076-1 (level 3).
429 Interoperability is granted, provided that the same performance level as defined in 4.3.1 and
430 the same surface of contacts as defined in 6.2 is considered.
431 4.4 Classification into climatic categories
432 See 6.3 in this standard.
433 4.5 Creepage and clearance distances
434 The creepage and clearance distances shall be dimensioned according to rated insulation
435 voltage values specified in Table 30 (see 6.4.1), in accordance with IEC 60664-1 and shall be
436 measured only in mated position according to IEC 60512-1-2.
437 NOTE – Creepage distances are defined for pollution degree 2 for connectors IP54 or higher, see IEC 61984
438 (2008), subclause 6.19.3
