Scope

Scope and object 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) 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 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) dielectric properties; 3) terminals.
