CAN/CSA E60730-2-10:13 (R2023) ✓ Most Recent

Preface This is the second edition of CAN/CSA-E60730-2-10, Automatic electrical controls for household and similar use - Part 2-10: Particular requirements for motor-starting relays, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 60730-2-10 (second edition, 2006-10). It supersedes the previous edition published in 1994 as CAN/CSA-E730-2-10, Automatic electrical controls for household and similar use - Part 2: Particular requirements for electrically operated motor starting relays (adopted IEC 730-2-10:1991).

This Standard is intended to be used in conjunction with CAN/CSA-E60730-1:02, Automatic electrical controls for household and similar use - Part 1: General requirements (adopted IEC 60730-1:1999, with Canadian deviations).

This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.

Scope and normative references

This clause of Part 1 is applicable except as follows:

1.1 Replacement:

This part of IEC 60730 applies to controls for automatically controlling the starting windings of single phase motors associated with equipment for household and similar use.

This standard applies to motor-starting relays using NTC or PTC thermistors, additional requirements for which are contained in Annex J.

1.1.1 This 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 motor-starting relays used in, or in association with, household or similar equipment.

Motor-starting relays for equipment not intended for normal household use, but which nevertheless may be used by the public, such as equipment intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard.

This standard does not apply to motor-starting relays designed exclusively for industrial applications.

Throughout this standard, the word "equipment" means "appliance and equipment". The words "starting relay" mean "motor-starting relay".

1.1.2 This standard applies to starting relays incorporating electronic devices and starting relays using thermistor elements, thermal elements and magnetic elements.

1.1.3 This standard does not apply to general purpose relays or to contactors and motor starters of the type covered by the IEC 60947 series1. This standard does not apply to mechanical timers or mechanically operated motor-starting devices.

1.1.4 This standard applies to manual controls when such are electrically and/or mechanically integral with starting relays.

Requirements for manual switches not forming part of a starting relay are contained in IEC 61058-1.
