| Title | Low-voltage switchgear and controlgear - Part 4-2: Contactors and motor-starters - AC semiconductor motor controllers and starters |
| Project Number | 22830 |
| Abstract/Scope | IEC 60947-4-2:2011 applies to a.c. semiconductor motor controllers and starters, which may include a series mechanical switching device, intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V a.c. This standard characterizes a.c. semiconductor motor controllers and starters with and without bypass means. This third edition replaces the second edition published in 1999 and its Amendments 1 (2001) and 2 (2006). It is a technical revision. This edition includes the following significant technical changes with respect to the previous edition and its amendments: - updated EMC normative references and associated requirements, - new references to IEC 60947-1, - marking of electronic relays without thermal memory, - marking of tripping time at 0 °C ambient or below, - new test requirements for limits of operation of time-delay overload relays, - new classes of overload current withstand time, - damp heat, salt mist, vibration and shock tests, - short-circuit test in the smallest enclosure, - update of the routine and sampling tests. This publication is to be read in conjunction with IEC 60947-1:2007. |

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
