The series circuit breakers possesses four rated frames: 125A、250A、400A、800A, the current specification 40A ~ 800A.

• 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
• With the function of Automatic Reclosing
• External plug and plug type anti module Built in infrared communication debugging interface
• With over voltage protection, under voltage protection and phase failure protection
• 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℃, Particular measures should be taken for occasional condensation due to temperature fluctuation.

Pollution grade: 3

Ⅲ for primary circuit of 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.
