Product Overview
GSW1 series universal circuit breakers(abbreviated circuit breakers as follow) could be suited for distribution net including frequency:50Hz、rated working voltage:400V、690V、rated current:200～6300A；and used for assigning the electrical energy and the protection line and the power equipment exempting such as overloaded,undervoltage,short-circuits,and single-phase earth harm,The circuit breaker has the intellectualized protection function, the selective protection is precise, which can enhance the power supply the reliability,and avoid the nonessential power cut，Compact structure、small volume and high Breaking Capacity.The seal contact system establishing zero overflash,The intelligent controller has test、load monitoring、great information display、real-time programming and communication function, which might establish perfect three sections or four section of protections
Product feature
Whole specifications，five frame current rated current from 200A to 6300 A
GSW1-1600 universal circuit breaker
△ the min dimensions：width：254mm
volume：254mm（W）×329.5mm（H）×254mm（D）
△ high breaking ability Icu=65kA，Ics=Icw=55kA
GSW1-6300 universal circuit breaker
△ the max current：to 6300A
△ high breaking ability Icu=120kA,Ics=Icw=100kA
■ Reliable operation in the harsh conditions of high and low temperature
Low-temperature： -40℃：storage，-25℃：work
High-temperature：+70℃：storage、work
■ Resistance to impact and vibration
Acceleration of impact：12g Acceleration of vibration：0.5g
■ Work in wide-voltage：AC/DC80～280V
■ Used as Switch－disconnectors、load-switch
Applied environment
△ Ambient temperature:－5℃～＋40℃
average temperature in 24 hours ≤+35℃
△ Relative humidity
No exceeding 50% at the maximum ambient temperature of 40℃ .With
lower temperature ,higher humidity would be permitted, for instance:with
temperature 20℃，the humidity can exceed 90%. Take the special measure
to the dews on the surface, which would appear due to temperature change.
△ Pollution protection:3grade
△ Installation categories
IV for the major circuit and III for auxiliary circuit except undervoltage release and primary circuit of transformers,whose installing categories is IV
△ The breaker should be installed vertically，andvertical bank angle shall not exceed 5°
