The series circuit breakers possesses four rated frames: 100A、250A、400A、8000A, the current specification 16 A ~ 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
• The breaker can be divided into Electricity and motor protection by purpose.
• 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
