JM1L Series RCBO

1. Scope of use

JM1L series residual current circuit breakers (hereinafter referred to as RCBOs) are mainly suitable for distribution networks with AC 50Hz, rated voltage AC400V, and insulation voltage up to 800V. They are used to provide indirect contact protection for  people,  prevent fire hazards caused by equipment insulation damage and ground fault  currents,  and can be used to distribute electrical energy and protect circuits and power  equipment from overload and short circuits, It can also be used for infrequent switching of circuits and infrequent starting of motors. The working power supply of the conventional leakage protection module with RCBO is sampled as two phases. This series of RCBOs is 3 phase. If any phase is missing, the leakage protection module of the RCBO can still work normally. The rated residual operating current In and maximum disconnection time can be  adjusted on-site according to actual conditions: When the phase voltage drops to 50V, the   leakage protection module can still operate normally and has a leakage alarm output function.

The product meets the standards of IEC60947 and GB14048. 2

4. Normal application,  installation,  and transportation conditions

Normal usage conditions:

a)The upper limit of the ambient air temperature shall not exceed+40℃, the lower limit shall not be lower than -5℃ , and the average value within 24 hours shall not exceed+35℃ .

Note: Circuit breakers used under conditions where the ambient air temperature is above+40℃ or below -5℃ should  be negotiated with the manufacturer.

b)The height of the poster at the installation site shall not exceed 2000m;

c)The relative humidity of the atmosphere does not exceed 50%at the highest ambient temperature of+40     ℃;At  lower  temperatures, there  can  be  higher  relative  humidity(e. g. 90%at  20℃), taking  into  account  the condensation on the surface of the product caused by temperature changes

Normal  installation  conditions:

a)Installation  conditions: Generally, it  should  be  installed  vertically  or  horizontally;

b)Installation category: Circuit  breaker  main  circuit  Class II, control  circuit  and  auxiliary  circuit  Class  ;

c)Pollution  level:Level  3;

d)External magnetic field:The external magnetic field near the installation site shall not exceed 5 times the geomagnetic field in any direction.
