SIST EN 60730-2-10:1997/A2:2002

SIST EN 60730-2-10:1997/A2:2002 is the Slovenian adoption of CENELEC amendment A2 to EN 60730-2-10:1995, based on IEC 60730-2-10:1991/A2:2001. It applies to motor starting relays for household and similar use and tightens the information and heating-test points that manufacturers and test laboratories use to declare and check motor current conditions.

What does SIST EN 60730-2-10:1997/A2:2002 specify?

SIST EN 60730-2-10:1997/A2:2002 specifies changes to the European standard for automatic electrical controls, specifically the part covering motor starting relays. The amendment is focused and updates only the clauses and table entries named in the document.

The structure shown in the amendment points to:

• Clause 7 - Information
• Table 7.2 - added requirement 601
• Clause 14 - Heating
• Clause 14.4 - added text for a reproducible heating test

What are the key requirements of SIST EN 60730-2-10:1997/A2:2002?

SIST EN 60730-2-10:1997/A2:2002 adds two practical requirements that affect declaration and testing. One concerns the current value the manufacturer must state, and the other sets the load conditions for the heating test so that results can be reproduced.

Table 7.2 - information to declare

Table 7.2 adds requirement 601 for steady state motor current - also called motor run current - with a link to Clause 14.4. In practice, the manufacturer has to declare the current the motor draws in steady operation, because that value is then used in the heating test.

Clause 14.4 - heating test setup

Clause 14.4 adds a specific heating-test condition. The contacts are not to be loaded with 1,06 times the rated current, and the coil is to be loaded with the motor run current declared by the manufacturer.

This matters because the test is meant to be reproducible. A laboratory or approval body needs the same loading conditions each time, so the declared motor run current becomes part of the test basis.

Clause 14 - relationship between contacts and coil loading

SIST EN 60730-2-10:1997/A2:2002 separates the load applied to the contacts from the load applied to the coil. That distinction matters in practice because the switching path and the energizing path are checked under different electrical conditions.

Common modifications

The amendment is described as a modified IEC text with CENELEC common modifications. In practical use, that means the European version is not just a direct copy of the IEC text - the documented European changes are part of the requirement set.

What terms does SIST EN 60730-2-10:1997/A2:2002 define?

SIST EN 60730-2-10:1997/A2:2002 uses a few key terms that matter for declaration and testing.

• Motor starting relays - relays used in the starting function of motors in household and similar automatic controls.
• Steady state motor current - the current drawn by the motor when it is running steadily.
• Motor run current - the term used alongside steady state motor current in the amendment; it is the value the manufacturer declares for the heating test.
• Rated current - the reference current used to set the contact loading condition.
• Contacts - the switching parts of the relay that carry the electrical load.
• Coil - the energizing winding of the relay, which is loaded separately in the heating test.

Who uses SIST EN 60730-2-10:1997/A2:2002?

SIST EN 60730-2-10:1997/A2:2002 is used by manufacturers of automatic electrical controls and motor starting relays, especially for household and similar applications. It is also relevant to test laboratories, certification teams, quality managers, and appliance engineers who need to declare motor current data or set up heating tests.

In practice, buyers and compliance teams use it when they need a common reference for how a motor starting relay should be described and tested.

What changed in SIST EN 60730-2-10:1997/A2:2002 from the previous edition?

SIST EN 60730-2-10:1997/A2:2002 is an amendment to EN 60730-2-10:1995. The change text adds requirement 601 in Table 7.2 and adds Clause 14.4 to set the heating-test loading conditions.

The foreword also gives the CENELEC approval date of 2002-09-01 and the national implementation and withdrawal dates of 2003-09-01 and 2009-09-01.

Which standards are used with SIST EN 60730-2-10:1997/A2:2002?

• EN 60730-2-10:1995 - the European standard that this amendment modifies.
• IEC 60730-2-10:1991/A2:2001 - the international text on which the amendment is based.

What does the SIST EN 60730-2-10:1997/A2:2002 document contain?

SIST EN 60730-2-10:1997/A2:2002 contains the amendment text, the foreword, the endorsement notice, and the common modifications agreed by CENELEC. The technical content shown in the document is concentrated in the update to Table 7.2 and the added text in Clause 14.4.

For testing and conformity work, the important parts are the declared steady state motor current and the revised heating-test arrangement for the contacts and coil. The document uses those points to make the test conditions clearer and more repeatable.
