Plastic circuit breaker is suited for distribution network of AC 50Hz,
Rated insulation voltage 800V (control loop insulation voltage 400V),
Rated working voltage up to 690V. It is applied to distribute electric
Power and protect the line and the equipment against the damage due to overload, underd-voltage and short circuit. Meanwhile, breaker with intelligent tripper can also selectively protect against the damage of short circuit and single phase earthing.

Breakers with frame size rated current 400A and below 400A can be used for protecting mouse-cage type motor's against unfrequently start, break down overload, and under voltage. This breaker conforms to IEC60947-2, GB14048-2.

Environment conditions for operation:

1. Ambient temperature: (centigrade)-5 ~ +40; The average value within 24h shall not exceed +35 centigrade.
2. Altitude of installation place shall not exceed 2000m.
3. Relative humidity at +40 centigrade shall not exceed 50%. Higher humidity is permissible At lower temperature condition. When the highest monthly average relative humidity is 90% in the humiddest month, the lowest monthly average temperature of this month is +25 centigrade. And the influence of dew on product surface due to temperature changes should be taken into consideration.
4. Pollution grade: Grade iii.
5. Installation instruction: Horizontally and vertically installations
