IEC 60730-2-10:2026 PDF

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",
