Just like conventional fuses, circuit breakers serve to protect against overloads and short circuits by interrupting the circuit of the application. Their advantage over a normal fuse is that they can do this many times without having to be replaced each time after tripping. The vending machine can be returned to its original state via automatic or manual reset - saving time and money. The circuit breakers can distinguish between time-limited inrush current and a real overload, so that optimum protection can always be guaranteed without false tripping or wasted energy. The version with manual release gives the user the option of conveniently and quickly interrupting a circuit and then closing it again by manual reset - ideal for a large number of electrical tests, such as those that occur in the automotive workshop.
