Motor starter

Abstract

A motor starter includes: a motor circuit breaker which has an electronic tripping device; a contactor which is correspondingly interconnected to the motor circuit breaker for forming the motor starter; and at least one control line disposed between the motor circuit breaker and the contactor, via which control line a control signal, which is generated depending upon a switching signal for switching the contactor, is transmitted from the contactor to the electronic tripping device. The electronic tripping device generates a tripping signal for switching off a current flow across the switching contact or switching contacts of the motor circuit breaker, depending upon the control signal and current flow across one or more switching contacts of the motor circuit breaker.
