1., Application
Moulded case circuit breaker is suitable for the circuit with AC 50/60HZ, rated voltage can be 690V and
below, the rated current up to 630A. Generally, if the rated current under 630A, the circuit breaker can
be used as motor protection. Normally the breakers can be used as circuit of infrequency conversion
and motor infrequently starting.

2., The working environment
Temperature: -5~+40 centigrade, Average temperature cannot exceed +35 centigrade in 24 hours.
Relative humidity: the highest temperature is 40 centigrade, cannot be more than 50%, Relatively low
temperature allows relatively high humidity, such as: 20 centigrade, humidity is 80%
The altitude must not exceed 2000 meters.
Should use in a place where without explosion danger medium in the air, no corrosive action on metals
and damage insulation and without conductive dust.
Also cannot use in place where will be attacked by snow and rain, The pollution level is level 3.

Internal Accessories
Internal accessories of AKM1, AKM2, AKM3, and AKM4 series: undervoltage release, shunt release
and auxiliary alarm release, their main technical parameters and wiring diagram are as follows:
Undervoltage release
Rated voltage of power supply Main features
AC230
AC400
A., Undervoltage release should act
when voltage drops to within 70%
and 35% of the rated voltage.
B., The undervoltage release should not
be able to close to prevent the circuit
breaker from closing when voltage is
lower than 35% of the rated voltage.
C., The undervoltage release should en-
sure to be closed and ensure reliable
closing of the circuit breaker when
voltage is equal to or greater than
85% of the rated voltage.
Shunt release
Rated voltage of power supply Main features
DC24,
AC230, AC400
Shunt release can work reliably when the
rated voltage value is at 70% and 110%.
Auxiliary alarm contact
Rated voltage of power supply Main features
Auxiliary switch Provides distinctive signals for the circuit
breaker at „ON” and „OFF” positions.
Alarm switch
Provides distinctive signals for the circuit
breaker at „normal work” and „trip”
positions.
Auxiliary alarm switch
Provides distinctive signals for the circuit
breaker at „close”, „open” and „trip”
positions.

Attention:
(1) If an undervoltage release is used, then it
must be energized to circuit breaker can be
switched on.
(2) Undervoltage release cannot be installed with
shunt release at the same time.
(3) Shunt, undervoltage release needs to install
from the right side, auxiliaries and alarming
contact need to install from the left side.
AKM3
AKM4
(1) If an undervoltage release is used, then it must
be energized to circuit breaker can be swit-
ched on.
2) Alarming contact need to install from the left
side; auxiliaries shunt, under voltage device
can be installed both left and right.

Installation
1. Check whether the nameplate of the circuit breaker meets the requirements before
installation. The cross section of the copper wire must match the rated rating of the
circuit breaker current.
2. All screws must be tightened during installation.
3. The cover of circuit breaker can not be opened, it’s parameters has been set and qu-
alified in the factory, please do not adjust it!

Use and maintenance
• Read the instruction carefully before installation and use!
• Must be used under normal working conditions!
• Before installation, make sure that the type meets the requirements or not!
• After all the wires are connected, check and then turn on the power switch!
• Circuit breakers must be properly installed and must not be abnormal mechanical
stress!
• Improper use, dropping, improper installation, external weather or natural disasters
are not warranty cases!
• Before commissioning, the circuit breaker handle must be moved up and down several
times. The structure must operate flexibly and reliably.
• In case of a general fault in the operating circuit, the circuit breaker trips and the hand-
le is in the middle position.
• If users want to close breaker after release, firstly find cause and remove the fault, pull
the handle down, in „OFF” position, then pull the handle to the „ON” position.
• The outer surface of the circuit breaker must always be cleaned of dust in order to
maintain good insulation.
