CM1-630 AC MCCB Molded case circuit breaker

1.Application Area
CM1 series molded case circuit breaker are mainly applied to distribution system of 50HZ,rated insulation voltage 690V,rated current up to 1250A.It's purpose lays in power system distributing & protecting against malfunctions such as overload,short-circuit,undervoltage,etc.It also can be used as infrequent ON/OF switch under power system in normal conditioin.
Sorted by ultimate short-circuit breaking capacity,CM1 breakers can be defined as Model L(standards type),& Model M(high breaking capacity type).They're well-known for compact shape,high breaking capacity and short flashover distant,etc.
CM1 breakers can be either vertically or horizontally installed.
CM1 breakers comply to GB14048.2 standards,with CCC,CE approved.

2.Model Code

3.Work Circumstance
3.1 Altitude of the installation place shall not be higher than 2000m(in case it's higher,do ask for advice from manufacturer first)
3.2 Circumstance temperature shouldn't ne higher than +40℃ or lower than -5℃,average temperature of 24h shouldn't exceed +35℃.
Attention:If temperature breaks the limits issued above,users shall operate the product according parameter shown in user manual or contat manufacturer for advice.
3.3 Working area shall not contain any explosive,metal corrosive or inductive media,the palce also should weatherproof.
3.4 Relative atmosphere humidity shall not exceed 50% when circumstance temperature is at 40℃,relative humidity could be higher if temperature drops,the average humidity of the most humid month shall not exceed 90%,in the meantime,average temperature of this month shall not be lower that +25℃,condensation on product surface due to temperature changing should be taken into consideration as well.
