The series circuit breakers possesses seven rated frames: 63A、100A、250A、400A、630A、800A, current specification 10 A ~ 800 A.

• limited short circuit breaking capacity can be divided into L type (Typical), M type (High breaking type);
• All series circuit breaker can be installed horizontally (lateral), vertical (vertical) and horizontal installation;
• Whole series of breaker with isolation function
• The circuit breaker can be configured with a transparent cover, which can observe the Splitting or Integrating state of moving and stationery contact-header.
• 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℃, Particular measures should be taken for occasional condensation due to temperature fluctuation.

Pollution grade: 3
