3 Phase Mccb Circuit Breaker Mccd 63a Mccb 32A 3 Pole Mccb Electric Switch Three-phase Plastic Shell air Switch
MKB6,MKB6E,MKB6EL series of circuit breakers are new upgraded circuit breakers researched and developed by
the company combined with the advantages of simila international products and demand of domestic and
international markets. With insulation voltage up to 1000V,the circuit breaker is applicable for distribution
systems of AC50Hz,rated working voltage 690V and rated working current from 10A to 800A,used to distribute
electric power energy.protect circuits and power equipment against overload,short circuit,under voltage and
so on,also can be used for infrequent startup of motor and protect it from overload,short circuit or under voltage.
It is featured with smallsize,high breaking,short flash over,et,is the ideal product for users,it can be
vertically installed or horizontally installed.YOM6DC series DC moulded-case circuit breaker(hereinafter referred to
as circuit breaker)is suitable for DC systems of rated voltage up to and including DC 1000V and rated current
10~800A,used to distribute electric power energy.protect circuits and power equipment against overload,short
circuit and so on.The products can be fed with wires from top and bottom,and it is polarity-free.It complies with the
standards IEC60947-2 GB14048.2.etc.
