Product Description

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 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
