17 I.S. EN : IEC:1999+:2006 +A2:2011 INTERNATIONAL ELECTROTECHNICAL COMMISSION LOWVOLTAGE SWITCHGEAR AND CONTROLGEAR Part 43: Contactors and motorstarters AC semiconductor controllers and contactors for nonmotor loads FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international cooperation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as IEC Publication(s) ). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and nongovernmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC has been prepared by subcommittee 17B: Lowvoltage switchgear and controlgear, of IEC technical committee 17: Switchgear and controlgear. This standard shall be used in conjunction with IEC This consolidated version of IEC consists of the first edition (1999) [documents 17B/1000/FDIS and 17B/1013/RVD], its amendment 1 (2006) [documents 17B/1486/FDIS and 17B/1510/RVD], its amendment 2 (2011) [documents 17B/1727/FDIS and 17B/1735/RVD] and its corrigendum of May The technical content is therefore identical to the base edition and its amendments and has been prepared for user convenience. It bears the edition number 1.2.

18 I.S. EN : IEC:1999+: A2:2011 A vertical line in the margin shows where the base publication has been modified by amendments 1 and 2. Annexes A, D and I form an integral part of this standard. Annexes B, E, F, G, H and J are for information only. The committee has decided that the contents of the base publication and its amendments will remain unchanged until the stability date indicated on the IEC web site under " in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended.

19 I.S. EN : IEC:1999+:2006 +A2:2011 INTRODUCTION This part of IEC covers lowvoltage a.c. semiconductor controllers and contactors (solidstate contactors) intended for the use with nonmotor loads. As controllers, they have many capabilities beyond the simple switching on and off of nonmotor loads. As contactors, they perform the same functions as mechanical contactors, but utilize one or more semiconductor switching devices in their main poles. The devices may be singlepole or multipole (see of IEC ). This standard refers to complete devices rated as a unit incorporating all necessary heatsinking material and terminals. It includes devices with all necessary terminals, which are supplied with or without heatsink in knockeddown form for combination by the users, when the manufacturer gives with the device detailed information about choosing the heatsink and mounting the device on the heatsink. The generic term, "controller", is used in this standard wherever the unique features of the power semiconductor switching elements are the most significant points of interest. The generic term "contactor" is used in this standard wherever the feature of simple switching on and off is the most significant point of interest. Specific designations (for example, form 4, form HxB, etc.) are used wherever the unique features of various configurations comprise significant points of interest. The provisions of the general rules (IEC ) are applicable to this standard, where specifically called for. Clauses and subclauses thus applicable, as well as tables, figures, and annexes, are identified by reference to IEC , for example 1.2.3, table 4 of IEC or annex A of IEC

20 I.S. EN : IEC:1999+: A2:2011 LOWVOLTAGE SWITCHGEAR AND CONTROLGEAR Part 43: Contactors and motorstarters AC semiconductor controllers and contactors for nonmotor loads 1 Scope and object This part of IEC applies to a.c. semiconductor nonmotor load controllers and contactors intended for performing electrical operations by changing the state of a.c. electric circuits between the ONstate and the OFFstate. Typical applications are given in table 2. As controllers, they may be used to reduce the amplitude of the r.m.s. a.c. voltage on the load terminals from that of the applied voltage either continuously or for a specified period of time. The halfwave period of the a.c. wave form remains unchanged from that of the applied voltage. They may include a series mechanical switching device and are intended to be connected to circuits, the rated voltage of which does not exceed V a.c. This standard characterizes controllers and contactors for use with or without bypass switching devices. The semiconductor controllers and contactors dealt with in this standard are not normally intended to interrupt shortcircuit currents. Therefore, suitable shortcircuit protection (see 8.2.5) should form part of the installation but not necessarily of the controller itself. In this context, this standard gives requirements for semiconductor controllers and contactors associated with separate shortcircuit protective devices. This standard does not apply to operation of a.c. and d.c. motors; lowvoltage a.c. semiconductor motor controllers and starters covered by IEC ; electronic a.c. power controllers covered by IEC 60146; allornothing solidstate relays. Contactors and controlcircuit devices used in semiconductor controllers and contactors should comply with the requirements of their relevant product standard. Where mechanical switching devices are used, they should meet the requirements of their own IEC product standard and the additional requirements of this standard.

21 I.S. EN :2000 The object of this standard is to state IEC:1999+:2006 +A2:2011 a) the characteristics of semiconductor controllers and contactors and associated equipment; b) the conditions with which semiconductor controllers and contactors should comply with reference to their operation and behaviour; their dielectric properties; the degrees of protection provided by their enclosures, where applicable; their construction; c) the tests intended for confirming that these conditions have been met, and the methods to be adopted for these tests; d) the information to be given with the equipment or in the manufacturer's literature. 2 Normative references The following referenced documents are indispensable for the application of this document.
