Notes
H) Having requested a Uaux insulated from earth, one must use “galvanically separated converters” in
compliance with IEC 60950 (UL 1950) or equivalent standards that ensure a common mode current
or leakage current (see IEC 478/1, CEI 22/3) no greater than 3.5 mA, IEC 60364-41 and CEI 64-8.
I) If the application in figure 21 and the contacts in figure must be installed at the same time, contact
Q/2 must be installed in the adjacent cable (marked Q/1).
Caption
A17 = Actuator unit type MOE for the stored energy motor operator H2 = Signalling lamp for blocked
stored energy motor operator
J.. = Connectors for the auxiliary contacts of the withdrawable version circuit-breaker; extraction of the
connectors takes place at the same time as that of the circuit-breaker
KO = Auxiliary opening relay
M = Motor with excitation in series for opening and closing the circuit-breaker (fig. 21)
M = Motor for opening the circuit-breaker and spring charging for closing the circuit-breaker (fig. 22)
R1 = Resistor (see note H)
S1 = Contact controlled by the cam of the motor operator
S2 = Contact controlled by the key lock of the motor operator with direct action
S3/1-2 = Contacts controlled by the Auto/Manual selector and key lock of the stored energy motor operator
S6/1-2 = Contacts controlled by the Auto/Manual selector of the motor operator with direct action
SC = Pushbutton or contact for closing the circuit-breaker
SO1,S02 = Pushbuttons or contacts for opening the circuit-breaker (see “Instructions for resetting the circuit-
breaker following release tripping”)
SY/1..3 = Contacts for electrical signalling of circuit-breaker open due to tripping of the thermomagnetic trip
units, YO, YO1, YO2, YU (tripped position)
V1 = Circuit-breaker applications
V2 = Motor operator applications
V4 = Indicative apparatus and connections for control and signalling, outside the circuit-breaker
XB.. = Three-way connector for the plug-in version circuit-breaker auxiliary circuits
XC.. = Six-way connector for the plug-in version circuit-breaker auxiliary contacts
XD.. = Nine-way connector for the auxiliary circuits of the plug-in version circuit-breaker
