The series circuit breakers possesses five rated frames: 160A、250A、400A、8000A、1250A, the current specification 16 A ~ 1250A.

• All series circuit breaker can be installed horizontally (lateral), vertical (vertical) and horizontal installation;
• Whole series of breaker with isolation function
• The circuit breaker meet the use requirements of installation site with the altitude not exceeding 2000 meters above sea level
• The outlet and inlet of circuit breaker with protective cover
• The breaker can be divided into Electricity and motor protection by purpose.
• The intelligent controller may be divided into M Type (typical) and H Type (communicative).
• Working conditions

The surrounding medium temperature ranging from -5℃ to +40℃, average value within 24 hours not over +35℃.

Altitude not exceeding 2000 meters above sea level

Relative humidity of installation site not over 50% at an ambient temperature of +40℃ yet higher humidity is permissible at lower temperature, e.g. 90% at 20℃(humid type circuit breaker at 25℃ is 95%), Particular measures should be taken for occasional condensation due to temperature fluctuation.

Pollution grade: 3

Ⅲ for primary circuit of the circuit breaker is suitable for Electromagnetic environment A. and coils of undervoltage releases and Ⅱ for auxiliary circuits and control circuits.

The circuit breaker is suitable for Electromagnetic environment A. should be installed in places where there is no potential explosion risk nor electric conducting dust, nor metal corrosion and insulation damage situations.

The circuit breaker is suitable for Electromagnetic environment A. should be installed in places where there is no rain and snow.
