40 Automatic electrical controls –
41 Part 2-25: Particular requirements for current sensing controls
43 FOREWORD
44 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national
45 electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all
46 questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC
47 publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and
48 Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National
49 Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-
50 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the
51 International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two
52 organizations.
53 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus
54 of opinion on the relevant subjects since each technical committee has representation from all interested IEC National
55 Committees.
56 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in
57 that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC
58 cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.
59 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to
60 the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the
61 corresponding national or regional publication shall be clearly indicated in the latter.
62 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment
63 services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by
64 independent certification bodies.
65 6) All users should ensure that they have the latest edition of this publication.
66 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its
67 technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature
68 whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of,
69 or reliance upon, this IEC Publication or any other IEC Publications.
70 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable
71 for the correct application of this publication.
72 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC
73 shall not be held responsible for identifying any or all such patent rights.
74 This version XXXX
75 International Standard IEC 60730-2-25 has been prepared by technical committee TC 72: Automatic
76 electrical controls.
77 This edition includes alignment with the text of 60730-1 sixth edition.
78 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
79 This Part 2-25 is intended to be used in conjunction with IEC 60730-1. It was established on the basis
80 of sixth edition (2022) of that publication. Consideration may be given to future editions of, or
81 amendments to, IEC 60730-1.
82 This Part 2-25 supplements or modifies the corresponding clauses in IEC 60730-1 so as to convert that
83 publication into the IEC standard: Particular requirements for current sensing controls.
84 Where this Part 2-25 states "addition", "modification", or "replacement", the relevant requirement, test
85 specification or explanatory matter in part 1 should be adapted accordingly.
86 Where no change is necessary, this part 2 indicates that the relevant clause or subclause applies.

87 In the development of a fully international standard, it has been necessary to take into consideration the
88 differing requirements resulting from practical experience in various parts of the world and to recognize
89 the variation in national electrical systems and wiring rules.
90 This part of International Standard IEC 60730 has been prepared by IEC technical committee 72:
91 Automatic electrical controls.
92 In this publication:
93 1) The following print types are used:
94 – Requirements proper: in roman type;
95 – Test specifications: in italic type;
96 – Notes; in small roman type;
97 – Words defined in Clause 2: bold.
98 2) Subclauses, notes, tables and figures which are additional to those in part 1 are numbered starting
99 from 101, additional annexes are lettered AA, BB, etc.
100 A list of all parts of the IEC 60730 series, published under the title Automatic electrical controls can be
101 found on the IEC website.
102 The committee has decided that the contents of the base publication and its amendment will remain
103 unchanged until the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the
104 data related to the specific publication. At this date, the publication will be
105 • reconfirmed,
106 • withdrawn,
107 • replaced by a revised edition, or
108 • amended.
109 A bilingual version of this publication may be issued at a later date.

112 AUTOMATIC ELECTRICAL CONTROLS -
113 Part 2-25: Particular requirements for current sensing controls
114 1 Scope
115 This clause of Part 1 is replaced by the following:
116 This document applies to automatic thermo-electro-mechanical current sensing controls intended to
117 be incorporated or integrated into appliances. These products are designed to limit the load current
118 below a certain value to prevent a potential hazard due to misapplication or overloading condition during
119 user operation of the appliance. These products are:
120 for use in, on, or in association with appliances for household and similar use that are not in fixed
121 installation;
122 NOTE 101 Thermo-electro-mechanical current sensing controls regulate current by converting temperature changes into
123 mechanical movement. In these controls, a thermal element—commonly a bimetallic strip—bends in response to heat generated
124 by current flow, triggering a switching mechanism that limits or interrupts the current to ensure overload protection.
125 EXAMPLE 101 Controls for motor-operated appliances within the scope of IEC 60335 series.
126 for assembly within the scope of IEC 60884-2-7;
127 for equipment that is used by the public, such as equipment intended to be used in shops, offices,
128 hospitals, farms, and the like;
