CSA Preface

This is the third edition of CSA C22.2 No. 60730-2-11, Automatic electrical controls — Part 2-11: Particular requirements for energy regulators, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 60730-2-11 (third edition, 2019-05). It supersedes the previous edition published in 2018 as CAN/CSA-E60730-2-11 (adopted IEC 60730-2-11:2006). It is one in a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. For brevity, this Standard will be referred to as “CSA C22.2 No. 60730-2-11” throughout. This Standard is intended to be used in conjunction with CSA E60730-1:15, Automatic electrical controls — Part 1: General requirements (adopted IEC 60730-1:2013), Amendment 1:2017 (adopted IEC Amendment 1:2015), and Amendment 2:2021 (adopted IEC Amendment 2:2020), with Canadian deviations. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. This Standard was reviewed for Canadian adoption by the CSA Subcommittee on Automatic Controls for Household Use, under the jurisdiction of the CSA Technical Committee on Consumer and Commercial Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope and normative references This clause of Part 1 is applicable except as follows: 1.1 Scope Replacement: In general, this part of IEC 60730 applies to energy regulators for use in, on, or in association with equipment, 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.

NOTE These energy regulators can be thermally, mechanically or electrically operated. This standard applies to the inherent safety, to the operating values, operating times and operating sequence where these are associated with equipment safety, and to the testing of automatic electrical energy regulator devices used in, or in association with, equipment. This standard is also applicable to energy regulators for appliances within the scope of IEC 60335-1.

Throughout this standard the word “equipment” means “appliance and equipment”. This standard also applies to automatic electrical energy regulators for equipment that may be used by the public, such as equipment intended to be used in shops, offices, hospitals, farms and commercial and industrial applications. This standard does not apply to automatic electrical energy regulators designed exclusively for industrial process applications unless explicitly mentioned in the equipment standard. This standard does not apply to equipment that are specifically within the scope of building automation equipment. This standard 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. This standard applies to controls powered by primary or secondary batteries, requirements for which are contained within the standard, including Annex V.

1.1.1 This International Standard applies to the inherent safety, to the operating values, operating times, and operating sequences where such are associated with equipment safety, and to the testing of automatic electrical control devices used in, or in association with, equipment. This standard applies to controls using thermistors, see also Annex J. This standard is also applicable to the functional safety of low complexity safety related systems and controls.

1.1.2 This standard applies to energy regulators as defined in 2.2.10 of Part 1.

1.1.3 Not applicable.

1.1.4 Replacement: This standard applies to manual energy regulators which 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 61058-1.

1.1.5 Replacement: This standard applies to energy regulators with a rated voltage not exceeding 690 V AC or 600 V DC.

1.1.6 Not applicable.

1.1.7 Replacement: This standard applies also to energy regulators incorporating electronic devices, requirements for which are contained in Annex H.

1.1.8 This standard applies also to energy regulators using NTC or PTC thermistors, additional requirements for which are contained in Annex J.

1.1.9 This standard applies to the electrical and functional safety of controls capable of receiving and responding to communications signals, including signals for power billing rate and demand response. The signals may be transmitted to or received from external units being part of the control (wired), or to and from external units which are not part of the control (wireless) under test.

1.1.10 This standard does not address the integrity of the output signal to the network devices, such as interoperability with other devices unless it has been evaluated as part of the control system.
