Specifications

1. Application
GSW1 series of Air circuit breaker is used in AC 50Hz circuits with rated operational voltage up to 690V, rated operational current from 200A to 6300A, for power distribution or preventing circuit and current supply devices from damage caused by overloading, under-voltage, short-circuit and single phase earthing.
Feature: compact structure, small volume, high breaking capacity, closed contact system, none-flashover and intelligent control.
Standard: IEC60947-2
Type of application: B
2. Working condition and installation condition
Ambient temperature: -5 to +40℃, and the average temperature in a 24 hour period can not exceed +35℃.
Humidity is up to 50% at +40℃ ambient temperature, and 90% at 20℃.
Site altitude: ≤ 2000m
Pollution degree: 3
Installation category: 3,4
3. Type structure
GSW1 series universal circuit breaker has two type structure, the one is draw-out breaker, the other is fixed breaker, the two type structure breaker have the same Main technical paraments. But there are some different character for use between the two type breaker.
The advantage of the draw-out socket is: it' s easy to install and maintenance. And the disadvantage is: the breaker is bigger, heavier and more expensive, for which used more material.
Compared to the draw-out breaker , the fixed breaker is smaller, lighter and cheaper , but the disavdantage of the fixed breaker is difficult to install and maintenance.
The draw-out socket is connected to main circuit when plug body busbar to contact bridge, there are three work positions:
" connect" position, " test" position and " seperated" position. The three positions are changed for each other by The handle, which is rotated to forward and backward. The three position indicator displayed by position indicator button which is located on the draw-out socket' s downside.
" connect" position: main and auxiliary circuit are both connect
" test" position: the main circuit is disconnect, safety seperator is closed, only auxiliary circuit is connect, the necessary action test could be done
" seperated" position: the main and auxiliary circuit are both disconnect, and the body of breaker could be pull out.
The breaker could be closed only in connect or test position and it can not be closed in the middle position
There are two type of the body of breaker: fixed and draw-out, there is one different struct between fixed breaker body and draw-out breaker body: busbar. The fixed breaker body' s busbar is longer than the draw-out breaker body' s.The other struct is in same. There is the sameOutline dimensions in the same rated frame current bodys, but different rated current , different busbar and intelligent controllor.
Used to enhance the electrical gap and creepage distance
used to prevent the dust to falling in terminals of secondary circuit
There is a arc-extiguish chamber for each pole, to play the role of seperating
all the poles and isolating them for each other and arc-extiguish
Frame Current Specification there are five classes frame Current
Specification of Intelligent Controller:
GSW1-1600; GSW1-2000; GSW1-3200; GSW1-4000; GSW1-6300
The Rated Current of GSW1-1600 including:
200,400,630,800,1000,1250,1600
The Rated Current of GSW1-2000 including:
630,800,1000,1250,1600,2000
The Rated Current of GSW1-3200 including: 2000,2500,3200
The Rated Current of GSW1-1600 including: 4000
The Rated Current of GSW1- 6300 including: 4000,5000,6300
To close or break the circuit breaker
GSW1-1600 series universal circuit breaker' s terminal of secondary circuit has 57 contacts. GSW1-2000, GSW1-3200, GSW1-4000, GSW1-6300 series universal circuit breaker' s terminal of secondary circuit has 47 contacts
The undervoltage release consists of coil and control unit;
The undervoltage release works in two ways: acting instantaneously and time delay;
The undervoltage release delay time can be adjusted from 1s to 10s, and the
time delay accuracy is ± 20%;
If the voltage of power supply of main circuit returned to 85%Ue or above in
Half of the delay time, the breakers wound not break away .
