Operating state shown
The diagram is shown in the following conditions:
– circuit-breakers open and racked-in #
– with de-energized circuits
– trip units not tripped *
– unloaded closing springs.
Key
A = ATS021 and ATS022 devices for automatic switching of two circuit-breakers
CB1-N = Normal supply line circuit-breaker
CB2-E = Emergency supply line circuit-breaker
K1 = Auxiliary contactor type NF22E for voltage presence of normal power supply
K2 = Auxiliary contactor type NF22E for voltage presence of emergency power supply
KC1-KC2 = Auxiliary contactors type AL__-30 for the closing of the circuit-breakers
KO1-KO2 = Auxiliary contactors type AL__-30 for the opening of the circuit-breakers
M = Motor for loading the closing springs
Q/1 = Auxiliary contact of the circuit-breaker
Q60 = Thermal relay for isolating and protecting the auxiliary circuits of safety auxiliary voltage
Q61/1-2 = Thermal relays for isolating and protecting the auxiliary circuits of the lines
S11 = Contact for enabling automatic switching of the ATS021 device
S11…S15 = Signalling contacts for the inputs of the ATS022 device
S1-S2 = Contacts controlled by the cam of the motor operator
S3 = Changeover contact for electrical signalling of local/remote selector state
S33M/1 = Limit contacts of spring loading motor
S51 = Contact for electrical signalling of circuit-breaker open due to tripping of overcurrent trip unit
S75I/1 = Contact for signalling circuit-breaker racked-in #
BUS 1 = Serial interface with control system (MODBUS EIA RS485 interface) available with the device ATS022
X = Connector for auxiliary circuits of withdrawable version circuit-breakers
XF = Delivery terminal box for the position contacts of the circuit-breaker
XV = Delivery terminal box for the auxiliary circuits of the fixed version circuit-breakers
YC = Shunt closing release
YO = Shunt opening release
# This diagram shows the withdrawable version circuit-breakers, but it is also valid for the fixed version circuit-breakers.
In this case, it is not necessary to connect the S75I/1 contacts on the X31:1 input of the ATS021 device otherwise it is
necessary to connect the X32:5 and X32:6 terminals with the terminal X32:9 of the ATS022 device.
* This diagram shows circuit-breakers with overcurrent release but it is also valid for circuit-breakers without release (switchdisconnectors). If the S51 contact is not present, the S51contacts on the X31:1 input of the ATS021 device should not be
considered, while it is necessary to connect the X32:7 and X32:8 terminals with the X32:9 terminal of the ATS022 device.
