Automatic electrical controls - Part 2-11: Particular requirements for energy regulators
IEC 60730-2-11:2025 applies to energy regulators
• for use in, on, or in association with equipment for household appliance and similar use;
NOTE 1 Throughout this document, the word "equipment" means "appliance and equipment" and "controls" means "energy regulators".
• for equipment that is used by the public, such as equipment intended to be used in shops, offices, hospitals, farms and commercial and industrial applications;
EXAMPLE 1 Energy regulators for commercial catering, heating and air-conditioning equipment.
• that are smart enabled energy regulators;
EXAMPLE 2 Smart grid control, remote interfaces/control of energy-consuming equipment including computer or smart phone.
• that are AC or DC powered controls with a rated voltage not exceeding 690 V AC or 600 V DC;
• used in, on, or in association with equipment that use electricity, gas, oil, solid fuel, solar thermal energy, etc., or a combination thereof;
• utilized as part of a control system or controls which are mechanically integral with multifunctional controls having non-electrical outputs;
• using NTC or PTC thermistors and to discrete thermistors, requirements for which are contained in Annex J;
• that are mechanically or electrically operated, responsive to or controlling such characteristics as temperature, pressure, passage of time, humidity, light, electrostatic effects, flow, or liquid level, current, voltage, acceleration, or combinations thereof;
• as well as manual controls when such are electrically and/or mechanically integral with automatic controls.
NOTE 2 Requirements for manually actuated mechanical switches not forming part of an automatic control are contained in IEC 61058-1-1.
This document applies to
- the inherent safety of energy regulators, and
- functional safety of energy regulators of low complexity safety related systems and controls,
- controls where the performance (for example the effect of EMC phenomena) of the product can impair the overall safety and performance of the controlled system,
- the operating values, operating times, and operating sequences where such are associated with equipment safety.
- manual energy regulators which are electrically and/or mechanically integral with automatic controls.
- energy regulators incorporating electronic devices, requirements for which are contained in Annex H.
- 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 can 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.
This document specifies the requirements for construction, operation and testing of automatic energy regulators used in, on, or in association with an equipment.
This document does not
• apply to automatic energy regulators intended exclusively for industrial process applications unless explicitly mentioned in the relevant part 2 or the equipment standard. However, this document can be applied to evaluate automatic energy regulators intended specifically for industrial applications in cases where no relevant safety standard exists.
• take into account the response value of an automatic action of an energy regulator, if such a response value is dependent upon the method of mounting the energy regulator in the equipment. Where a response value is of significant purpose for the protection of the user, or surroundings, the value defined in the appropriate equipment standard or as determined by the manufacturer will apply.
• 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.

• à commande mécanique ou électrique, qui réagissent à des caractéristiques telles que la température, la pression, le passage du temps, l'humidité, la lumière, les effets électrostatiques, le débit ou le niveau d'un liquide, le courant, la tension, l'accélération, ou une combinaison de ces caractéristiques, ou qui les régulent;
• ainsi qu'aux dispositifs de commande manuels qui sont électriquement et/ou mécaniquement intégrés à des dispositifs de commande automatique.
NOTE 2 Les exigences relatives aux interrupteurs mécaniques à action manuelle qui ne font pas partie d'un dispositif de commande automatique sont contenues dans l'IEC 61058-1-1.
Le présent document s'applique
− à la sécurité intrinsèque des régulateurs d'énergie; et
− à la sécurité fonctionnelle des régulateurs d'énergie des systèmes et dispositifs de commande de sécurité peu complexe;
− aux dispositifs de commande pour lesquels les performances (par exemple, l'effet des phénomènes CEM) du produit peuvent compromettre la sécurité et les performances globales du système commandé;
− aux valeurs de fonctionnement, aux temps de fonctionnement et aux séquences de fonctionnement lorsque ces éléments interviennent dans la sécurité du matériel;
− aux régulateurs d'énergie manuels qui sont électriquement et/ou mécaniquement intégrés à des dispositifs de commande automatique;
− aux régulateurs d'énergie qui incorporent des dispositifs électroniques, dont les exigences figurent à l'Annexe H;
− à la sécurité électrique et la sécurité fonctionnelle des dispositifs de commande capables de recevoir et de répondre à des signaux de communication, y compris les signaux propres au taux de facturation de l'électricité et à la gestion de la demande.
Les signaux peuvent être transmis ou reçus d'unités externes qui font partie intégrante du dispositif de commande (câblé), ou vers et depuis des unités externes qui ne font pas partie intégrante du dispositif de commande (non câblé) soumis à l'essai.
Le présent document spécifie les exigences relatives à la construction, au fonctionnement et aux essais des régulateurs d'énergie automatiques utilisés dans, sur ou avec du matériel.
Le présent document
• ne s'applique pas aux régulateurs d'énergie automatiques destinés exclusivement à des applications de processus industriels, sauf mention particulière dans la partie 2 applicable ou la norme
