Circuit breaker and fuse in the role of what in common
In common: both are circuit protection appliances, used to achieve the overload and short circuit protection of the circuit breaker.
Fuse is actually a short circuit protector, widely used in power distribution systems and control systems, mainly for short circuit protection or severe overload protection.
And a combination of overheat relays and the like. Fuses are also known as fuses, which are installed in the circuit to ensure the safe operation of the circuit electrical components
when they have a serious overload or short circuit and undervoltage failure can automatically cut off the circuit, its function is equivalent to the fuse switch
Circuit breakers can be used to distribute power, not frequently start the asynchronous motor, the power lines and motors and other protection
