5.2 When the Rated Control Power Voltage of Shunt Release is: AC50Hz,
230V,400V;DC110V、220、24V， external voltage lied the Rated Control
Power Voltage from 70% ～ 110%，it could break the Circuit Breaker
reliably.
Note：when Voltage Specification select DC24V, Rated Current should
attain 5A ± 10%A.
5.3 When the Power Voltage reduce to the 70% ～ 35% scope of
Undervoltage Release’s rated working voltage, Undervoltage Release
could break the Circuit Breaker reliably; when the Power Voltage
reduce below 35% of Undervoltage Release’s rated working voltage,
Undervoltage Release could prevent Circuit Breaker closure; when the
Power Voltage is higher than 85% of Undervoltage Release’ s rated
working voltage, Undervoltage Release could guarantee Circuit Breaker
reliably closed.
5.4 The rated working voltage and relevant parameters of Alarm
Contact, please see form 5. When Circuit Breaker is at normal
break-close, alarm contact unoperate ; only when at the tripping
automatically or faulty tripping, contact will change the original

7.2 The various features and accessories of the circuit breaker is
adjusted by the manufacturer, which can’t be adjusted randomly
when it is used.
7.3 The handle of the circuit breaker can in three position, which
mean three conditions, such as close, open and trip. When the
handle is the position of trip, you should push the button back,
making the circuit breaker re-trip, then switching on.
7.4 Notice of installation
·It must be installed on the flame retardant.
·It can’t be installed in the environment including explosion
gas.
·It can’t be installed in the particular damp place.
·It can’t be installed in the place, where the external
magnetic field is bigger than the five-fold geomagnetic field.
·It can’t be installed in the place, where the shake is
bigger than 5g.
·It can’t be installed in the place, where the round gas can
corrode metal and destroy insulation.
7.5 Note
·The circuit breaker can’t be operated frequently, or it
will shorten the working life of the circuit breaker.
·If the circuit breaker has the undervoltage release, the
undervoltage release should be electrified first, then the circuit
breaker can re-trip and switch on, or it will damage the circuit
breaker.
·After the circuit breaker with the motor-operated mechanism
tripping, the motor-operated mechanism should make the circuit
breaker re-trip, then it can switch on.
7.6 Notice for the first-time running
·Checking the connection and technical data, especially the
input terminal of the circuit breaker(1).
3、5）should connect to the power supply terminal, the output
(2、4、6) should link to load side.
Using the megger between the phase compares the earth to
measure the insulation resistance ( not less than 20MΩ)。
Making sure terminals connected and the fixed screws should
be tightening.
The operating handle should be flexible and the urgent shunt
release button should be pressed in the close position (under
condition of no load, the operating handle should in the position
of shunt release.
If there is under-voltage release, the under-voltage release
should be electrified, the closing operation can go on.
8、Notice
8.1 The unauthorized detachment is strictly prohibited, or else
you will bear the risk.
8.2 If the product has cover and arc extinction board, the cover
and extinction board must be installed before using it, or else
you will bear the risk.
8.3 The installation、maintenance and examination should be done
by the qualified professionals.
8.4 It is prohibited to operate the circuit breaker with the wet
hand, or else the electrical accident might happen.
8.5 If the circuit breaker cuts because the protected circuit
faults (overload or short circuit), we must know the reason. After
solving the problems, we can do the close operation.
8.6 When the circuit breaker does short-circuit breaking test, it
should use the special testing device, which has passed the
examination of relevant department and it is strictly prohibited
to use the testing way by making the phase line connect directly.
8.7 When the equipment is electrified, you can’t make an
installation and maintenance. You must make sure there is no
voltage before working and you should obey the routine safety
regulations

5.2 When the Rated Control Power Voltage of Shunt Release is: AC50Hz,
230V,400V;DC110V、220、24V， external voltage lied the Rated Control
Power Voltage from 70% ～ 110%，it could break the Circuit Breaker
reliably.
Note：when Voltage Specification select DC24V, Rated Current should
attain 5A ± 10%A.
5.3 When the Power Voltage reduce to the 70% ～ 35% scope of
Undervoltage Release’s rated working voltage, Undervoltage Release
could break the Circuit Breaker reliably; when the Power Voltage
reduce below 35% of Undervoltage Release’s rated working voltage,
Undervoltage Release could prevent Circuit Breaker closure; when the
Power Voltage is higher than 85% of Undervoltage Release’ s rated
working voltage, Undervoltage Release could guarantee Circuit Breaker
reliably closed.
5.4 The rated working voltage and relevant parameters of Alarm
Contact, please see form 5. When Circuit Breaker is at normal
break-close, alarm contact unoperate ; only when at the tripping
automatically or faulty tripping, contact will change the original

7.2 The various features and accessories of the circuit breaker is
adjusted by the manufacturer, which can’t be adjusted randomly
when it is used.
7.3 The handle of the circuit breaker can in three position, which
mean three conditions, such as close, open and trip. When the
handle is the position of trip, you should push the button back,
making the circuit breaker re-trip, then switching on.
7.4 Notice of installation
·It must be installed on the flame retardant.
·It can’t be installed in the environment including explosion
gas.
·It can’t be installed in the particular damp place.
·It can’t be installed in the place, where the external
magnetic field is bigger than the five-fold geomagnetic field.
·It can’t be installed in the place, where the shake is
bigger than 5g.
·It can’t be installed in the place, where the round gas can
corrode metal and destroy insulation.
7.5 Note
·The circuit breaker can’t be operated frequently, or it
will shorten the working life of the circuit breaker.
·If the circuit breaker has the undervoltage release, the
undervoltage release should be electrified first, then the circuit
breaker can re-trip and switch on, or it will damage the circuit
breaker.
·After the circuit breaker with the motor-operated mechanism
tripping, the motor-operated mechanism should make the circuit
breaker re-trip, then it can switch on.
7.6 Notice for the first-time running
·Checking the connection and technical data, especially the
input terminal of the circuit breaker(1).
3、5）should connect to the power supply terminal, the output
(2、4、6) should link to load side.
Using the megger between the phase compares the earth to
measure the insulation resistance ( not less than 20MΩ)。
Making sure terminals connected and the fixed screws should
be tightening.
The operating handle should be flexible and the urgent shunt
release button should be pressed in the close position (under
condition of no load, the operating handle should in the position
of shunt release.
If there is under-voltage release, the under-voltage release
should be electrified, the closing operation can go on.
8、Notice
8.1 The unauthorized detachment is strictly prohibited, or else
you will bear the risk.
8.2 If the product has cover and arc extinction board, the cover
and extinction board must be installed before using it, or else
you will bear the risk.
8.3 The installation、maintenance and examination should be done
by the qualified professionals.
8.4 It is prohibited to operate the circuit breaker with the wet
hand, or else the electrical accident might happen.
8.5 If the circuit breaker cuts because the protected circuit
faults (overload or short circuit), we must know the reason. After
solving the problems, we can do the close operation.
8.6 When the circuit breaker does short-circuit breaking test, it
should use the special testing device, which has passed the
examination of relevant department and it is strictly prohibited
to use the testing way by making the phase line connect directly.
8.7 When the equipment is electrified, you can’t make an
installation and maintenance. You must make sure there is no
voltage before working and you should obey the routine safety
regulations
