Overview

prEN IEC 60730-2-3:2026 sets out the particular requirements for thermal protectors specifically designed for ballasts used in tubular fluorescent lamps. Developed by the International Electrotechnical Commission (IEC) under the CLC, this standard ensures the inherent and functional safety of automatic electrical controls employed in household and similar applications, with a focus on thermal protection in lighting systems. It supersedes SIST EN 60730-2-3:2008.

Thermal protectors addressed in this standard are integrated or incorporated within ballasts to guard against overheating, thereby preventing risks such as electrical fires, premature equipment failure, and safety hazards to users and property. The document aligns with IEC 60730-1 (Edition 6) and is relevant to both electromechanical and electronic designs as well as controls using NTC or PTC thermistors.

Key Topics

The main focus areas of prEN IEC 60730-2-3:2026 include:

• Scope of Application: Covers thermal protectors for ballasts in public, commercial, and industrial lighting installations, with rated voltages up to 690 V AC or 600 V DC.
• Safety and Functional Requirements: Assures both inherent safety (to avoid electric shock, fire, and thermal risk) and functional safety (correct operation and reliability under endurance and overload conditions).
• Technical Information and Marking: Specifies the technical data manufacturers must provide, including operating values and sequences related to safety, and criteria for micro-disconnection.
• Constructional and Performance Testing: Addresses mechanical, electrical, and thermal tests, including endurance and overload cycles, to ensure sustained functionality over time.
• Protection Features: Defines requirements for electric shock protection, insulation, moisture and dust resistance, resistance to heat, fire, corrosion, and electromagnetic compatibility (EMC).
• International Applicability: Incorporates national differences for the US, Canada, Japan, and CENELEC member countries, making it broadly relevant for global markets.

51 FOREWORD
52 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
53 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
54 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
55 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
56 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
57 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
58 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
59 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
60 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
61 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
62 consensus of opinion on the relevant subjects since each technical committee has representation from all
63 interested IEC National Committees.
64 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
65 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
66 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
67 misinterpretation by any end user.
68 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
69 transparently to the maximum extent possible in their national and regional publications. Any divergence between
70 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
71 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
72 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
73 services carried out by independent certification bodies.
74 6) All users should ensure that they have the latest edition of this publication.
75 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
76 members of its technical committees and IEC National Committees for any personal injury, property damage or
77 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
78 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
79 Publications.
80 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
81 indispensable for the correct application of this publication.
82 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
83 rights. IEC shall not be held responsible for identifying any or all such patent rights.
84 IEC 60730-2-3 has been prepared by IEC technical committee 72: AUTOMATIC ELECTRICAL
85 CONTROLS. It is an International Standard.
86 This 3.0 edition cancels and replaces the 2.0 edition published in 2006. This edition constitutes
87 a technical revision.
