Manual motor protective circuit breakers Ex9S80A provide overload, short-circuit and phase-failure protection for the three-phase asynchronous motors with not frequent starting. They are also suitable for power distribution line protection or can be used simply as an isolator. The right setting of adjustable overload current allows to optimize motor protection by means of circuit breaker. In case of 3P application, correct setting of Ir provides also protection against overload caused due to a phase lost. Ambient temperature compensation function reduces the impact of ambient temperature. Release testing mechanism enables to test the function of the system and control rotary knob lock mechanism prevents illegal operation. Motor protective circuit breakers can be combined with wide range of accessories including auxiliary and signal contacts, shunt trip and undervoltage releases. It is possible to create diverse combination of accessories.
