Working conditions
ambient
temperature -5 ℃ ~ + 40 ℃, daily average value ≤ 35 ℃
Note: the circuit breaker used when the ambient air temperature is higher than + 40 ℃ or lower than -
5 ℃ shall be negotiated with the manufacturer
altitude ≤2000m
ambient
humidity The relative humidity of the atmosphere shall not exceed 50% at the highest ambient tempe
40 ℃; higher relative humidity is allowed at lower temperature (for example, 90% at 20 ℃), taking into
account the frost on the product surface due to temperature change
electromagnetic
interference Applicable to environment A
Degree of
protection The circuit breaker is installed in the cabinet chamber and equipped with door frame, with the protection
level up to IP40
Maintenance procedures
Regular inspection required
Interval time Operation mode
annually Turn on and off local and remote devices, and use various auxiliaries
successively
Test operator column
Small test suite for control unit test
Every two years or when the maintenance
index of the controller unit reaches 100 Check the arc extinguishing chamber
Check contact system
Check the tightness of the connection
Parts need to be replaced according to the number of business cycles
The following parts must be replaced regularly to extend the service life of the equipment (the maximum
value of the business cycle)
accessory Intervening entity
Arc extinguishing chamber user
Electric operating mechanism user
Mechanical interlock user
link spring user
Shunt coil / closing coil / undervoltage coil user
Maintenance operations
1 Each rotating part shall be regularly filled with lubricating oil during use
2 Regular maintenance shall be carried out to remove dust so as to maintain the insulation level of the circuit breaker
3 The contact system shall be inspected regularly, especially after each short circuit breaking. The inspection contents are
as follows:
 The flame marks on the two walls of the arc extinguishing chamber are clear, whether the arc extinguishing
wall is broken or not, and whether the arc extinguishing grid is seriously burned, which needs to be replaced
in time according to the situation
 Whether the contact is in good contact and the contact thickness is ≤ 1mm, it needs to be sent to the
manufacturer for replacement
 Whether the connecting parts are loose

After the breaker fault is broken, the controller can light up to indicate the cause of the fault. After the power
is cut off, it still has the memory function. After the power is turned on again, press the "fault check" key on
the control panel to indicate the information of the last fault trip. If a new fault occurs, clear the past fault
memory and keep the new fault memory
Note: the simulated power-off of the test state is not memorized. Press the "reset" key once after the inspection to make the
controller enter the normal state
