5.5 Control circuits
Replace the existing text by the following:
Subclause 4.5 of IEC 60947-1 applies; moreover, for an electronically controlled electro-
magnet, 4.5.1 of IEC 60947-1 applies with the following addition.
The electronic part may form an integral part or a separate part provided it is an intrinsic
function of the device. In both cases, the device shall be tested with this electronic part
mounted as in normal use.
The characteristics of electronic control circuits are as follows:
− type of current;
− power consumption;
− rated frequency (or d.c.);
− rated control circuit voltage, U (nature: a.c./d.c.);
c
− rated control supply voltage, U (nature: a.c./d.c.);
s
− nature of external control circuit devices (contacts, sensors, optocouplers, electronic
active components, etc).
Annex E gives examples and illustrations of different circuit configurations.
NOTE A distinction is made between the control circuit voltage U , which is the controlling input signal, and the
c
control supply voltage U , which is the voltage applied to energize the power supply terminals of the control circuit
s
equipment and may be different from U due to the presence of built-in transformers, rectifiers, resistors, electronic
c
circuitry, etc.

5.8 Co-ordination with short-circuit protective devices
Replace the existing text by the following:
The co-ordination of contactors and starters is characterized by the type, ratings and
characteristics of the short-circuit protective devices (SCPD) that provide protection of the
contactor and starter against short-circuit currents. Requirements are given in 8.2.5.1 and
8.2.5.2 of this standard, and in 4.8 of IEC 60947-1.

Subclause 7.1.6 of IEC 60947-1 applies with the addition of the following paragraphs to
subclause 7.1.6.1 of that standard.
Devices provided with positions like trip position or stand-by position which are not the
indicated open position shall be clearly marked.
An actuator having only one position of rest shall not be considered as appropriate to indicate
the position of the main contact.

8.2.1.2 Limits of operation of contactors and power-operated starters
Replace the existing text of this subclause as follows:
8.2.1.2.1 Electromagnetic contactors and starters
Electromagnetic contactors, whether used separately or in starters, shall close satisfactorily at
any value between 85 % and 110 % of their rated control supply voltage U . Where a range is
s
declared, 85 % shall apply to the lower value and 110 % to the higher.
The limits between which contactors shall drop out and open fully are 75 % to 20 % for a.c.
and 75 % to 10 % for d.c. of their rated control supply voltage U . Where a range is declared,
s
20 % or 10 %, as the case may be, shall apply to the higher value and 75 % to the lower.
Limits for closing are applicable after the coils have reached a stable temperature
corresponding to indefinite application of 100 % U in an ambient temperature equivalent to
s
the ambient temperature declared by the manufacturer but not less than +40 °C.
Limits for drop-out are applicable with the coil circuit resistance at −5 °C. This can be verified
by calculation using values obtained at normal ambient air temperature.
The limits apply to d.c. and a.c. at declared frequency.
8.2.1.2.2 Contactors and starters with electronically controlled electromagnet
Subclause 8.2.1.2.1 applies with the following modification.
Replace the second paragraph as follows:
The limits between which contactors with an electronically controlled electromagnet shall drop
out and open fully are
− for d.c.: 75 % to 10 % of their rated control supply voltage U
s,
− for a.c.: 75 % to 20 % of their rated control supply voltage U ,
s
− for a.c.: 75 % to 10 % of their rated control supply voltage U if specified by the
s
manufacturer,
− for a.c., where a range is declared with limits between 75 % to 10 % of their rated control
supply voltage U , the contactor shall, in addition, be submitted to the capacitive drop out
s
test of 8.2.1.2.4.
Where a range is declared, 20 % or 10 % as the case may be, shall apply to the higher value
of the range and 75 % to the lower value of the range.
