Scope of aplication

      YNM1LE series with resldual current protection moulded case circult breaker is one of new breakers using international advanced design and technique. Rated isoiation voltage is 800V. It is used in circuit with AC 50Hz, rated working voltage 400V, rated working current 225A for change frequently and start not frequently. The breaker has protection functions of over load, short circuit and under voltage to protect circuit equipment from damage, and offers fire protection since long-term ground fault .

      Based on rated maximum short circuit breaking capacity, the beaker can be H type (higher) and L type(highest).The breaker has small size, high breaking capacity, short arcing and vibration proof.

     The breaker can be installed vertically or horizontallyy.

     The breaker can not inverse leadin. Only 1,3,5 connect with power line and 2,4,6 connect with load line can be allowed.

Main characteristic

regular electrical leakage protection module with residual current protection cuse cituit Breaker who se power source is two-phase The series of moulded cuse circuit breaker has fhree-phase even if lack ang one phase,the electrical leakage protection module can stiu work regularly.
Based on reality, rated resting electric current 1Δn and maximum opening time can been shifted
when voltage lower to sov, electrical leakage protection module still works normally
be provided with the function of electrical leakage alarm
accord nith the demands of electromagnetic compatibility
outline volume is same size as ajm1 series breaker,so that it can be exchanged.
working conditions

Height above sea lever under 2000m;
Ambient temperature from -5°c to +40°c,and average temperature less than 35°c(except for peculiar products);
Relative humidity is not more than 50°c in +40°c. It can be hgiher in low temperature. And the lowest temperature can not be less than +25°c in the most humid month. In this month, average relative humidity can not be more than 90%, considering bead produced by temperature change.
