1. 20 years manufacturing experience 
2. competitive price,high quality 

3. Type: iron body of AC electric motor
Low voltage circuit breaker is www.facebook.com/guohong.trading generally divided into plastic shell type (also known three electric motors phase induction motor as the device type) and frame type (also called universal type) two kinds big. The motor under 380 v245kw and more choose molded case circuit breaker. Circuit breaker can be divided into the generator distribution line protection according to the use and protection, lighting protection circuit of the motor and electric leakage protection use and so on. 2.1 motor protection circuit breaker selection principles: (1) the set values for the long time delay current is equal to the rated current of the motor. (2) the instantaneous current setting: for the protection of cage motor circuit breaker, the adjusting current diesel engine instantaneous equal to 8 to 15 times the rated current of the motor, depending on the squirrel cage induction motor protected cage motor model, capacity and starting conditions.

For wound rotor motor protection circuit breaker, the adjusting current instantaneous is equal to (3 ~ 6) times the rated current of the motor, diesel generator set depending on the protected wound rotor motor model, capacity and starting diesel generator set conditions. (3) 6 times of long time delay current setting value can return time is greater than or equal to the starting time of the motor. According to the weight of the starting load, can choose to return time 1 s, 3 s, 5 s, one of an 8 s, 15 s. 2.2 circuit water pump price breaker tripping device setting current simplified formula: "instant-on, motor kw 20 times" "thermal trip, according to the rating of the above formula is to protect a 380 v control of three-phase cage type motor circuit breakers, instantaneous motion setting its electromagnetic tripping current, according to the number of" kw "20 times". For thermal trip, according to the rated current of the motor selection.
