1.Scope of Application

The YEPN series high-separation miniature circuit breakers are designed for single-phase residential circuits with AC 50Hz and rated voltages up to 230V,providing protection against overloads and short cicuits.These compact devces feature high breaking capacity and a slim profile of just 18mm in width.Their simultaneous interruption of neutral and live wires eliminates risks oflive wire contact,neutral wire reversal,or neutral-to-ground potential hazards,making them the most ideal distribution protection switch for residential applications.

Nomal working conditions:
a.The altitude is not more than 2000m;

b.The ambient temperature was not higher than +40℃ and not lower than-5℃,and the 24h average temperature was not higher than+35℃.

c.The relative humidity of the surrounding air should not exceed 50%when the ambient air humidity is +40℃.The maximum relative humidity of the most humid month is 90%and the average minimum temperature of the most humid month is +25℃.The condensation on the product is allowed due to the temperature change.
d.In the medium without explosion risk,there is no gas and dust enough to corrode metal and destroy insulation;
e.In places where there is no rain or snow.

2.Technical parameter

Pour:
1.This product is only for lighting protection.
2.Mechanical lifespan:20,000 cycles(on-off)Electrical lifespan:4,000 cycles

3.USE AND MAINTENANCE

3.1 The overload characteristic of this series of circuit breakers is set by the manufacturer,and it should not be adjusted at will in use,so as not to affect the performance.
3.2 The temperature of the circuit breaker is 30±5℃ If the circuit breakers are installed in the sealed box,the temperature of the box will increase accordingly.The current is0.8In.
3.3 When the ambient temperature changes,the rated current value is adjusted accordingly.
