Application RM1(CM1) series MCCB is mainly used in the circuit
of AC 50/60Hz,rated insulating voltage 690V (630 type is
500V),rated working voltage up to 690V,and rated current from
6A-800A in distribution line for distributing power,protecting
line,overload,short-circuit and under-voltage protection. It also
can be used for infrequently starting of motor for
overload,short-circuit and under-voltage protections.It is small
size,high breaking capacity and short arcing (without arcing).The
products can be installed vertically and horizontally.And it have
front connection,rear connection and plug-in connection.The product
meets the standards of GB14048.2 and IEC60947-2.Normal Working
Condition Altitude: not exceed 2000mAmbient air temperature:1)
Temperature: -5° C---+ 40° C2) 24 hours average air temperature
shall not exceed + 35° C3) If the air temperature is more than +
40° C, it need remark the special ordering.Air conditions:At
mounting site,relative humidity not exceed 50% at the max
temperature of +40° C,higher relative humidity is allowable under
lower temperature.For example,RH could be 90% at +20° C,special
measures should be taken to occurrence of dews.Pollution
