    4 pole Miniature Circuit Breaker Details

    Tips: Merits and demerits of various operating mechanism of the circuit breaker

    1. Manual operating mechanism. 
      Its separating and switching on speed depends on the manpower and proficiency of the operators. In other words, its reliability varies from person to person. If the system has any potential fault, the contact terminal of the circuit breaker will have weld melting and even explosion because of the great electromagnetic power or low closing speed.
    2. Electric energy reserving spring mechanism
      Merit: Fast closing and switching on speed, low motor power, can be used for AC and DC current.
      Demerit: Complicated structure, many components and high processing precision.
      Suitable for operating the middle-voltage circuit breaker, especially applicable to the power distribution system with small capacity.
    3. Pneumatic operating mechanism
      Merit: Fast movement, stable operation, small DC power, can still be operated for several times if the power is lost in short period.
      Demerit: High price and strict technology.
      Applicable to the high-voltage circuit breaker and also the middle-voltage circuit breaker.
    4. Electromagnetic operating mechanism
      Merit: Simple structure, reliable work and low manufacturing cost.
      Demerit: High power consumption of the closing coil, damaged component, heavy structure and long closing time.
    Existing reviews of 6 amp 4 pole Miniature Circuit Breaker
    I like this 10kA miniature circuit breaker
    I started to really like this 10kA miniature circuit breaker. It feels very stable, and it is easy to flip the switch or touch the reset button. After the installation is complete, everything is normal.
