Molded case circuit breaker

Key Attributes.

DNMl series breaker with plastic external shell (hereinafter called as the breaker) is one of new type of breakers produced and developed by us with the international advanced design and manufacturing technology. Its rated insulation voltage is 800V and is applicable to the electromotor which does not frequently switch in the line with AC 50Hz(60Hz), the rated operation voltage 690V and lower (DC 250V and lower) and the rated operation current from 10A to 1250A and does not frequently start. The breaker can prevent from the overload, short circuit and under-voltage and can protect the line and power device from damages, The breaker will be classified as the C type (basic type), L type (standard type) and M type (higher breaking type) by the breaking capability of the rated limit short circuit (Icu). This breaker features the small volume, high breaking, short splashing arc (zero splashing arc for partial specification) and shock resistance, so it is ideal for the land and ship. This breaker can be vertically installed and horizontally installed. This beaker includes the separation function and corresponding symbol. This beaker product will comply with the following standards: IEC947-1 and GBl4048.1 general principle IEC947-2 and GBl4048.2 low-voltage breaker IEC947-4 and GB 14048．4 contactor and electromotor starter IEC947-5.1 and GBl4048.5 mechanical and electronic control circuit appliance
