| Title | High-voltage switchgear and controlgear - Part 106: Alternating current contactors, contactor-based controllers and motor-starters |
| Project Number | 22829 |
| Abstract/Scope | IEC 62271-106:2011 is applicable to a.c. contactors and/or contactor-based controllers and motor-starters designed for indoor installation and operation at frequencies up to and including 60 Hz on systems having voltages above 1 000 V but not exceeding 24 000 V. It is applicable only to three-pole devices for use in three-phase systems, and single-pole devices for use in single-phase systems. Two-pole contactors and starters for use in single-phase systems are subject to agreement between manufacturer and user. This standard cancels and replaces the second edition of IEC 60470 published in 1999. It constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 60470:1999: - Scope and object: The voltage range covered by the standard was expanded from 12 kV to 24 kV. Overload relay calibration and testing is not covered by this standard. - 3 Terms and definitions: Added definitions for capacitor switching classes. - 4.1 Rated voltage: Added 15, 17,5 and 24 kV as standard voltage values. - 4.109.2 Starting duty of reduced-voltage starters: Added ratings for autotransformer and reactor starters (was in the testing section). - 4.112 Rated capacitive switching currents: Added capacitor switching current ratings. - 5.101 Protective relays: Removed the requirements for overload relays. This section is obsolete since there are only a few MV starters fitted with thermal overload relays and electronic relays have their own standards. - 6.2.5 Application of the test voltage and test conditions (former 6.2.2 b)): Changed wording of requirement for impulse across the open gap of vacuum contactors. - 6.4.2 Auxiliary circuits: The requirement for resistance checks of auxiliary circuits was deleted. - 6.5.5.104 Temperature rise of the auto transformer or reactor for two step auto transformer or reactor starters: Reworded to transfer ratings to subclause 4.109.2. - 6.102.9 Condition following making and breaking tests: Gave specific direction as to what the tolerance should be based on where the resistance was to be checked. - 6.104 Short-circuit current making and breaking tests: Clarified test conditions for short-circuit testing. - 6.109 Capacitive current switching tests: Added capacitive current switching tests. - Annex B: Added Table B.1 - Tolerances on test quantities for type test. |

(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
