Product Description
Application
RM1(CM1) series MCCB is mainly used in the circuit of AC 50/60Hz,rated insulating voltage 690V ,rated working voltage up to 690V,and rated current from 10A-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.
The product meets the standards of GB14048.2 and IEC60947-2.
Normal Working Condition
Altitude: not exceed 2000m
Ambient air temperature:
1) Temperature: -5° C---+ 40° C
2) 24 hours average air temperature shall not exceed + 35° C
3) 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 grade:Grade 3
Protection Grade: IP20
