National foreword
This British Standard has been prepared under the direction of the Light Electrical Engineering Standards Policy Committee and is the English language
version of EN 60730-2-11:1993 Automatic electrical controls for household and similar use — Part 2: Particular requirements for energy regulators including
amendments A1:1997 and A2:1998, published by the European Committee for Electrotechnical Standardization (CENELEC) It was derived by CENELEC from IEC publication 730-2-11:1993, first edition, including amendment 1:1994 and amendment 2:1997, published by the International Electrotechnical
Commission (IEC)
No CENELEC common modifications were approved to IEC 730-2-11:1993 However there are CENELEC common modifications to amendment 1 to IEC 730-2-11 and these are indicated by a sideline in the margin
This British Standard is to be read in conjunction with BS EN 60730-1:1992
General requirements which it supplements or modifies The many references to
Part 1 should be read as references to BS EN 60370-1 which is the English language version of EN 60730-1, which was derived from IEC
Publication 730-1:1986, first edition
The foreword of EN 60730-2-11 makes reference to the “date of withdrawal”, dow,
of the relevant, national standard In this case the relevant national standard is
BS 3955 which will cease to be applicable to controls within the scope of
BS EN 60730-2-11 on 1 July 1995 Certification and marks will not be awarded after this date with respect to BS 3955 However, such certification and marks, already awarded, may continue to apply to production until 1 July 2000
Product approval.
Attention is drawn to the fact that products conforming to this British Standard may be approved by the British Electrotechnical Approvals Board for the purposes of participation in the CENELEC Certification Agreement and in the
CB Scheme of the IECEE (Details of the BEAB Approval Scheme are given on the inside back cover)
A British Standard does not purport to include all the necessary provisions of a contract Users of British Standards are responsible for their correct application
Compliance with a British Standard does not of itself confer immunity from legal obligations.

This clause of Part 1 is replaced as follows:
1.1 In general, this part of International Standard
IEC 730 applies to energy regulators for use in, on,
or in association with equipment for household and
similar use, including energy regulators for heating,
air conditioning and similar applications The
equipment may use electricity, gas, oil, solid fuel,
solar thermal energy, etc or a combination thereof
This standard applies to energy regulators using
NTC or PTC thermistors, additional requirements
for which are contained in Annex J
These energy regulators may be thermally, mechanically or
electrically operated.
1.1.1 This Part 2 applies to the inherent safety, to
the operating values, operating times and operating
sequence where such are associated with equipment
safety, and to the testing of automatic electrical
energy regulator devices used in, or in association
with, household or similar equipment
Throughout this Part 2 the word “equipment” means “appliance
and equipment.”
This Part 2 does not apply to automatic electrical
energy regulators designed exclusively for
industrial applications
This Part 2 is also applicable to individual energy
regulators utilized as part of a control system or
energy regulators which are mechanically integral
with multi-functional controls having non-electrical
outputs
Energy regulators for equipment not intended for
normal household use, but which nevertheless may
be used by the public, such as equipment intended
to be used by laymen in shops, in light industry and
on farms, are within the scope of this standard
1.1.2 This Part 2 applies to manual energy
regulators when such are electrically and/or
mechanically integral with automatic controls
Requirements for manual switches not forming part
of an automatic energy regulator are contained in
IEC 1058-1
1.2 This Part 2 applies to energy regulators with a
rated voltage not exceeding 660 V and with a rated
current not exceeding 63 A
1.3 This Part 2 applies also to energy regulators
incorporating electronic devices, requirements for
which are contained in Annex H
