SW2 Series intelligent conventional breaker

SW2 for short series intelligent air circuit breaker(hereinafter called brea ker) is ap plied in the net work circuit 

of AC 50H z, rated isolating voltage up to 690V, rated voltage below 690V and rated current between 400A 

and 4000A. It is mainly used for power distribution and between 400A and 4000A.It is mainly used for power 

distribution and protecting the circuit and power supply device from short-circuit,under voltage, single phase 

ground fault, and etc. This ACB has functions of intelligent protection and four-step selective protection

which can prevent system from unnecessary power cut and enhance reliability of power supply. 

Impulse withstand voltage of the breaker is 12,000V. The product accords with IEC60947-2 and IEC60947-4.

Working and installation condition

1.Ambient temperature
Upper limit value is no more than +40, lower limit value is no less than -5 and average value in 24 hours is 
no more than +35
2.Installation altitude is under 2000m 
3.Air condition 
Relative air humidity is no more than 50% if ambient temperature is to be +40 Under the condition of 
lower temperature, relatively higher humidity is allowed, monthly average relative humidity is to be 90% 
in the most humid month, and meanwhile the lowest average temperature is to be +25 in this month.
3.Protection class: IP30
4.Application type: B type and A type
5.Mounting types: type of installing ACB and its under voltage release and primary coil of power transformer 
is to be IV; type of auxiliary circuit and controlling circuit is to be .
6.Mounting condition: mounting breaker as per this guide book and vertical gradient is no more than 5degree
