Danger:
●Do not operate the circuit breaker with wet hands;
●Do not touch the conductive part during operation;
●Power off the product before maintenance and repair;
●Do not test the product with a short-circuit way;
Attention:
●The installation, maintenance and repair shall be conducted by a qualified professional;
●All features of product have been set before shipment, and they cannot be removed or adjusted without
permission during operation;
●Before use, check that the rated voltage, rated current, frequency and features conform to the working
requirements;
●To prevent interphase short circuit, a phase partition is provided with the product. Please install this partition
properly before use, and the bare wire or copper bus of the wiring terminal shall be insulated to ensure safe
insulation;
●To test the insulation resistance or power frequency withstand voltage, first disconnect the electronic
components between the current loops, otherwise the product will be damaged;
●If found damage or heard abnormal sound when unpacking product, please stop use and contact the supplier;
●As the overload alarm non-trip product has no overload protection function, it is only suitable for overload
alarm non-trip site;
●Before powering on the product with a under-voltage release, apply the rated voltage onto the under-voltage
release;
●Please use all matching accessories provided by our company to ensure quality. Our company will not be
responsible for any adverse consequence due to the use of accessories not provided by our company;
●Please dispose the scrapped product waste properly. Thanks for your cooperation.
Test:
●As the overload alarm non-trip product has no overload protection function, it is only suitable for overload
alarm non-trip site;
●1000VDC megameter is used;
●The insulation resistance shall not be less than 20MΩ;

Between the contacts of circuit breaker, between the phases, and between the phase and the housing (the
housing is covered with metal foil);
Connected to the under-voltage release located between the incoming inlet and the circuit breaker housing
of main circuit;
Note: If no megameter is used by user, a power frequency withstand voltage tester can be used instead it for
testing. The measuring parts refer to the insulation test method, and the voltage 2000V shall be applied for 5
seconds.

Attention:
1. When the circuit breakers are installed in parallel, an insulation distance between the terminals shall be kept.
A long terminal cover or an extra phase partition is recommended between two products for insulation
protection;
2. If a more contact installation is required, a zeroarcing cover is recommendedto obtaina smaller safetydistance;
3. Please note the insulation protection of the mounting base to prevent that the ground clearance of the busbar,
terminal or screw is less than 8mm. It is recommended that the base plate attached on the long terminal cover
is installed or an additional ground insulation protection is provided.

Test requirements for internal accessories
1) Under-voltage release:
1.1) Under 35% ~ 70% rated working voltage, the under-voltage release can work to trip the circuit breaker;
1.2) Under 85% ~ 110% rated working voltage, the under-voltage release can work to power on the circuit
breaker reliably;
1.3) When the rated working voltage is below 35%, the under-voltage release can work to prevent powering
on circuit breaker;
2) When the shunt release is applied with 70%~110% rated voltage, the circuit breaker can be disconnected
reliably, and the handle is at the Trip position;
3) For circuit breaker with an auxiliary contact, the breaker can be closed and open normally and the conversion
signal of auxiliary contact shall be normal;
4) For circuit breaker with an alarm contact, the breaker shall be closed and tripped (with the red trip button
pressed), and the conversion signal of alarm contact shall be normal.
Attention:
1. When the rated power voltage of shunt release is DC24V, the maximum length of copper wire cannot exceed
the value listed in table below:
Rated control power voltage Us
(DC24V)
Sectional area 1.5mm2
Sectional area 2.5mm2

2. If the requirements of the above table cannot be satisfied, it is recommended that the shunt release control
circuit is designed according to the following figure:
Power input
3. The continuous power-on time of shunt release shall not exceed 5s, otherwise the shunt release will be burnt
out. When the selected rated control power voltage is DC24V, the rated current of control loop shall reach 4.5A
~ 5.5A.
4. The under-voltage release is of the backpack structure when delivery, and all other accessories are of the lead-
wire structure by default.
5. The default wire length for product of the lead-wire structure is about 500mm. If a longer lead length required
by user cannot drive the shunt or under-voltage release, the relay mode recommended in “Note 2” is used to
satisfy minimum drive power.
5.2 Overload alarm non-trip
Wiring diagram
Principle: The product uses one group of normally-open contacts. In case of overload fault of any phase in product,
the product will issue an alarm signal within a certain delay time. RB11 / RB14 means the wire code.

Attention:
1. The product without this function has no overload protection.
2. After the overload fault disappears, the product will be kept in the alarm state within some time due to thermal
effect.
3. The product has a lead-wire structure by default, and the default wire length is about 220mm.
6. Maintenance and service
Maintenance and service must be conducted by qualified professionals.
The product shall be de-energized.
The product shall be maintained and serviced once every year under the normal operating conditions, and the
maintenance items see Table below

operation
The handle shall be operated flexibly without blockage; this product uses a self-
clean contact structure. If found any change of the contact resistance due to
oxidization, please conduct multiple ON / OFF actions to realize the stripping of
oxidization layer between mobile and static silver points reducing the contact
resistance.
7. Unpacking inspection
After unpacking, please check the product for damage, check the exposed metal for rust, and check the product for
all defects due to poor transportation or storage. If found the above phenomenon, do not stop operating this product,
and contact the supplier in time.
