Starter combination
Starter combinations consist of: molded case circuit breaker + contactor
+ overload relay. The molded case circuit breaker handles short-circuit
protection and the isolating function. The contactor has the task of
switching the load feeder normally. The overload relay handles
overload protection that can be specially matched to the motor. The
molded case circuit breaker for starter combination is therefore
equipped with an adjustable and instantaneous short-circuit release.

Non-automatic air circuit breakers
These molded case circuit breakers are used as incoming circuit
breakers, main switches or isolating switches without overload
protection. They have fixed short-circuit releases so that back-up fuses
are not necessary.
