IEC 60730-2-11 ED4

Automatic electrical controls - Part 2-11: Particular requirements for energy regulators

Scope

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.
