Low-voltage switchgear and controlgear - Part 5-1: Control circuit devices and switching elements - Electromechanical control circuit devices (IEC 60947-5-1:2016)
This part of IEC 60947 applies to control circuit devices and switching elements intended for
controlling, signalling, interlocking, etc., of switchgear and controlgear.
It applies to control circuit devices having a rated voltage not exceeding 1 000 V a.c. (at a
frequency not exceeding 1 000 Hz) or 600 V d.c.
However, for operational voltages below 100 V a.c. or d.c., see 4.3.2.2.
This standard applies to specific types of control circuit devices such as:
• manual control switches, for example push-buttons, rotary switches, foot switches, etc.;
• electromagnetically operated control switches, either time-delayed or instantaneous, for
example contactor relays;
• pilot switches, for example pressure switches, temperature sensitive switches
(thermostats), programmers, etc.;
• position switches, for example control switches operated by part of a machine or
mechanism;
• associated control circuit equipment, for example indicator lights, etc.
NOTE 1 A control circuit device includes (a) control switch(es) and associated devices such as (an) indicator
light(s).
NOTE 2 A control switch includes (a) switching element(s) and an actuating system.
NOTE 3 A switching element can be a contact element or a semiconductor element.
It also applies to specific types of switching elements associated with other devices (whose
main circuits are covered by other standards) such as:
• auxiliary contacts of a switching device (e.g. contactor, circuit breaker. etc.) which are not
dedicated exclusively for use with the coil of that device;
• interlocking contacts of enclosure doors;
• control circuit contacts of rotary switches;
• control circuit contacts of overload relays.
Contactor relays also comply with the requirements and tests of IEC 60947-4-1 except for the
utilization category which comply with this standard.
This standard does not include the relays covered in IEC 60255 or in the IEC 61810 series,
nor automatic electrical control devices for household and similar purposes.
The colour requirements of indicator lights, push-buttons, etc., are found in IEC 60073 and
also in CIE S 0004/E-2001 from the Commission of Illumination (CIE).

Nizkonapetostne stikalne in krmilne naprave - 5-1. del: Krmilne naprave in stikalni elementi - Elektromehanske krmilne naprave (IEC 60947-5-1:2016)
Ta del standarda IEC 60947 se uporablja za krmilne naprave in stikalne elemente za krmiljenje, signalizacijo, spajanje itd. stikalnih in krmilnih naprav.
Uporablja se za krmilne naprave z nazivno napetostjo, ki ne presega 1000 V pri izmeničnem toku (pri frekvenci, ki ne presega 1000 Hz) ali 600 V pri enosmernem toku.
Za delovne napetosti pod 100 V pri izmeničnem ali enosmernem toku glej 4.3.2.2.
Ta standard se uporablja za posebne vrste krmilnih naprav:
• ročna krmilna stikala, na primer tipke, vrtljiva stikala, nožna stikala itd.;
• elektromagnetna krmilna stikala, zakasnitvena ali takojšnja, na primer kontaktorski releji;
• avtomatična krmilna stikala, na primer tlačna stikala, temperaturno občutljiva stikala (termostati), programatorji itd.;
• položajna stikala, na primer krmilna stikala, ki se upravljajo z delom stroja ali mehanizmom;
• povezana oprema za tokokroge, na primer indikatorske luči itd.
OPOMBA 1: Krmilna naprava vključuje (a) krmilna stikala in povezane naprave, kot so indikatorske luči.
OPOMBA 2: Krmilna stikala vključujejo (a) stikalne elemente in sistem za aktivacijo.
OPOMBA 3: Stikalni element je lahko kontaktni ali polprevodniški element.
Uporablja se tudi za posebne vrste stikalnih elementov, ki so povezani z drugimi napravami (njihove glavne tokokroge zajemajo drugi standardi), kot so:
• pomožni kontakti stikalne naprave (npr. kontaktor, odklopnik itd.), ki niso namenjeni izključno za uporabo s tuljavo te naprave;
• kontakti za spajanje ogradnih vrat;
• kontakti tokokrogov vrtljivih stikal;
• kontakti tokokrogov preobremenitvenih relejev.
Kontaktorski releji so v skladu tudi z zahtevami in preskusi standarda IEC 60947-4-1, razen kategorije uporabe, ki je v skladu s tem standardom.
Ta standard ne vključuje relejev, ki so zajeti v skupini standardov IEC 60255 ali IEC 61810, in samodejnih električnih krmilnih naprav za gospodinjske in podobne namene.
Barvne zahteve za indikatorske luči, tipke itd. so navedene v standardu IEC 60073 in tudi v standardu CIE S 0004/E-2001 Komisije za razsvetljavo (CIE).
