1.Internatonal standard: IEC 2.Authoritative certificate:CCC, CE,EU, TUV & ROHS 3.Rated Voltage:690V,Rated Current 800A

1.Application

GSM1 series moulded case circuit breakers suitable for turn-on or turn-off not frequently and starting a motor not frequently in the circuit of AC50Hz, rated insulation voltage up to 1000V(GSM1-63 is 800V), rated working voltage 690V or below(GSM1-63 is 400V), rated working current up to 800A.The breakers of 4 poles are mainly suitable for cable short cuicuit protection,cable overload protection and turn-on or turn-off not frequently in the power supply system.meanwhile can open neutral conductor and leg conductor together as to keep from high electric potential transferring and protect operators.Besides having short cuicuit and overload protection for cuicuit and motor,the breakers can assembly many function modules such as under-voltage realease,shunt release,alarm contact ,anxiliary contact,motor-driven operation device and so on,meeting all kinds of protection and control functions.

2.Conform to standards

 The breakers comply with the demands of the following standards:

 Low-voltage switchgear and controlgear: Low voltage breakers

 Low-voltage switchgear and controlgear: Part II Low voltage breakers .

 3.Environment condition for operate

Ambient temperature: -5°C~+40°C,the average of temperature not exceeding +35°C during 24 hours.

Elevation≤2000m.

 Relative humidity:not exceeding 50% at the maximum ambient temperature of +40.With lower temperature,higher humidity would be permitted, but the lowest average temperature in a month not exceeding +25°C during the most moist month,and the maximum monthly average relative humidity not exceeding 90% in that month,and giving consideration to the dews on the goods surface,which would appear due to temperature change.

Pollution protection:Grade 3.

 Installing categories:“Ⅲ”for breakers` main circuits, coils of under-voltage release and primary circuit of transformers;“Ⅱ”for other auxiliary circuits and control circuits.

 Be able to bear the influence of moisture in the air or salt fog and oil fog or mould or nuclear radiation.

The gradient≤22.5°.

Be working reliably under the condition of normal vibration on ship.

 Be working reliably when earthquake(4g)occuring.

There must be not any explosive medium, and there must be not any gas which would corrode metal or any conducting dust which would destroy the insulation.

The place would not be invaded by rain and snow.

4.Claasification of breakers

 According to the breaking ability (except GSM1-400,630,800 four poles breakers, having not the classification for four poles breakers):Typical type(Type L) Second high breaking type (Type M) High breaking type (Type H)

 According to the wiring method: Wiring in front of the board without patch board; Wiring on back of the board with patch board; Insertion connection in front of the board (onlyGSM1-100,225,250,400 have this type);Insertion connection on back of the board; Draw-out connection (only GSM1-400,630,800 have this type)

According to the operation means: Handle operating directly Turning handle Power driven.

According to the usage:Power distribution ;motor protection.

According to the pole number: two poles, Three poles, Four poles.

According to the release pattern: Thermo-electromagnetic(double) type release ;only has electromagnetic(instantaneous) type release.

According to the type of the neutral pole (N-pole)(having not the classification for two poles three poles products) Type A:N-pole without overcurrent release unit, it has been connected all along, and does not act with other poles to turn on or off Type B:N-pole without overcurrent release unit, it would act with other three poles.
