    Circuit Breaker Dimension

    circuit breaker dimensionTips: Difference between circuit breaker and contactor
    Circuit breaker plays a protective role in extinguish arc and disconnecting circuit. Contactor refers that coil is used for the on-off control of circuit. When contactor is charged, the circuit that is normally connected will be cut off and the circuit that is normally closed will be connected.

    1. Circuit breaker is mainly used for protection and its common protections include overload protection, short circuit short delay and short circuit delay. In addition, there are other protections that depend on brand and model, including under-voltage, over-voltage etc. Switch can be manually operated or electric-driven. Installation modes are various such as fixed installation and drawer etc. According to current and working voltage level, they can be divided into many types.
    2. Contactor mostly used in the industrial control is mainly introduced into manufacturing television. Of course, it also can be used in heater and double power switch. The on-off control of contactor is achieved by controlling coil voltage. According to different arc structures, they can be divided into vacuum contactor and standard contactor. According to different control voltage, they can be categorized into direct current contactor and alternating current contactor and its main accessories are auxiliary contactor.
