Scope of Application
OF and SD are suitable for auxiliary ON/OF contact. Can point out the disconnect or put through position of the circuit breaker ,can install on left of the Circuit Breaker.SD is with indication window for alarm.For use as the sound or light signal.Be applicable to instruct coherent broken state of circuit,chassis or front or reverse side of outer shell or operations area can see the signal instruction.Can be used for uniting the warning contact,Standard:IEC40947
MX SHUNT RELEASE is suitable for telecontrol release,can install on the right of the Circuit Breaker. Be applicable to telecontrol and disconnect electric circuit,connect with fire control warning system. Telecontrol release by emergent button. Rated Voltage(Un):AC 380V\220V\127V DC:48V\36V\24V.
HHGQ OVER/SHORT VOLTAGE RELEASE is to help the ciucuit breaker trips automatically when voltage decline to lower or raise than setting value. To ensure automatic tripping under situation of over voltage and under voltage MN is under voltage release with loss voltage protection.
