IEC 60730-2-10:2026 EXV

IEC 60730-2-10:2026 EXV contains both the international standard and its extended version (EXV). This extended version of the official IEC Standard is available in English only and provides the user with a comprehensive content of the Standard. IEC 60730-2-10:2026 EXV includes the content of the references made to IEC 60730-1:2022.

IEC 60730-2-10:2026 applies to automatic electrical motor-starting relays
- intended to control the start windings of single phase motors;
- 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 "control" means "motor-starting relays".
- intended for appliances within the scope of IEC 60335;
- for equipment that is used in building automation within the scope of ISO 16484 series and IEC 63044 series (HBES/BACS);
- 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 Controls for commercial catering, heating and air-conditioning equipment.
- used in, on, or in association with equipment that are smart enabled;
EXAMPLE 2 Smart grid control, remote interfaces/control of energy-consuming equipment.
- that are AC or DC powered 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, requirements for which are contained in Annex J;
- that are mechanically or electrically operated, responsive to or controlling such characteristics as current and voltage, or combinations thereof;
EXAMPLE 3 Centrifugal motor-starting devices.
- 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 motor-starting control, and
- functional safety of motor-starting control and safety related systems (when required),
- 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,
- motor-starting controls incorporating electronic devices, thermistor elements, thermal elements or magnetic elements.
This document specifies the requirements for construction, operation and testing of automatic electrical motor-starting relays used in, on, or in association with an equipment.
This document does not
- apply to motor-starting relays designed exclusively for industrial process applications unless explicitly mentioned in the relevant equipment standard. However, this document can be applied to motor-start relays for equipment intended specifically for industrial applications in cases where no relevant safety standard exists;
- take into account the response value of an automatic action of a control, if such a response value is dependent upon the method of mounting the control 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;
- apply to general purpose relays or to contactors and motor starters of the type covered by IEC 60947 series;
apply to mechanically operated motor-starting devices
This part 2-10 is intended to be used in conjunction with IEC 60730-1. It was established on the basis of the sixth edition of that standard (2022). Consideration may be given to future editions of, or amendments to, IEC 60730-1.
This part 2-10 supplements or modifies the corresponding clauses in IEC 60730-1, so as to convert that publication into the IEC standard: Particular requirements for motor-starting relays.
Where this part 2-10 states "addition", "modification" or "replacement", the relevant require­ment, test specification or explanatory matter in Part 1 should be adapted accordingly.
When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies.
This third edition cancels and replaces the second edition published in 2006. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) adoption of IEC 60730-1:2022 with all of its significant changes.
