Low voltage circuit breaker C45 series

C45 series is the introduction of merlin gerin (France) technology products,domestic models for DZ47.As the light distribution system,motor power distribution system and electrical control circuit overload protection and short circuit protection.3.The main technical parameters of low-voltage circuit breaker: 1) refers to the circuit breaker rated voltage under prescribed conditions for long-term running can withstand voltage,generally for the line voltage.Commonly used with ac 220 v,380 v,500 v,660 v,etc.2) rated current refers to the circuit breaker can be long-term wholesalemotor.blogspot.com under prescribed conditions by the current,rated current is known as the trip.

3) the rated short circuit making capacity Refers to the circuit breaker under the condition of single phase electric motorrated frequency and power factor and other rules,the ability to turn on the short

circuit current,with the maximum peak current said.4) rated short circuit breaking capacity Refers to

the circuit breaker and the rated frequency under specified conditions,such as power factor,to

breaking the maximum short-circuit current value.5) rated short-time resistance current Refers to the

circuit breaker under specified test conditions,can withstand current value within a specified

Dongfeng Electric between timely.From the action time of the 6):refers to the electrical control line began to contact separation,short circuit instantaneous arc extinguishing,circuit completely breaking all need time,also known as gasoline generator the breaking time,generally is 30 ~ 60 ms.
