38、TROLGEAR Part 5-1: Control circuit devices and switching elements Electromechanical control circuit devices 1 General The provisions of the general rules, IEC 60947-1, are applicable to this standard, where specifically called for. General rules, clauses and subclauses thus applicable, as well as ta
39、bles, figures and annexes are identified by a reference to IEC 60947-1, for example 1.2.3, Table 4 or Annex A of IEC 60947-1. 1.1 Scope and object This part of IEC 60947 applies to control circuit devices and switching elements intended for controlling, signalling, interlocking, etc., of switchgear
40、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 note 2 of 4.3.1.1. This standard applies to specific types of control circuit
41、 devices such as: manual control switches, for example pushbuttons, 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 (
42、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) in
43、dicator light(s). NOTE 2 A control switch includes (a) switching element(s) and an actuating system. NOTE 3 A switching element may 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
44、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 o
45、verload relays.

The colour requirements of indicator lights, pu
46、shbuttons, etc., are found in IEC 60073 and also in publication 2 of the International Commission of Illumination (CIE). The object of this standard is to state: a) The characteristics of control circuit devices. b) The electrical and mechanical requirements with respect to: 1) The various duties to
47、 be performed. 2) The significance of the rated characteristics and of the markings. 3) The tests to verify the rated characteristics. c) The functional requirements to be satisfied by the control circuit devices with respect to: 1) Environmental conditions, including those of enclosed equipment. 2)
48、 Dielectric properties. 3) Terminals. 1.2 Normative references The following referenced documents are indispensable for the application of this document.
