Intelligent controller is the core component of molded case circuit breaker. It is applied to motor protection or power distribution protection to realize the integration of measurement, protection, control and communication functions, so as to protect the line and power supply equipment from overload, short circuit, grounding and other fault hazards.

MCU microprocessor controller is adopted, with stable and reliable performance: the intelligent controller can provide power supply, as long as one phase is powered on, when the current is not less than 35% of its rated value, it can ensure the normal operation of the protection function;

□ Selective cooperation with three-section protection: use circuit breaker of category B and other short circuit protection connected in the same circuit. The device has selective coordination under short circuit conditions; Setting of overload long delay inverse time limit, short circuit delay (inverse time limit, definite time limit), short circuit instantaneous and other protection function parameters;
□ It has three parameter settings of action current and action time, and can be adjusted in 4-10 gears: users can adjust according to the load current requirements; the controller can be set and adjusted, and the corresponding functions can be selected to be closed according to the user’s requirements (customized functions, which need to be ordered by the us
er When specified);
□ Large current instantaneous tripping function: when the circuit breaker is closed and running, in case of short circuit large current ( 20 Inm), the magnetic tripping mechanism of the circuit breaker can directly trip, and the double protection is more reliable and safe;
□ With tripping test (test) function: input DC 12V voltage to test the action characteristics of circuit breaker;
□ Fault self-diagnosis function: protect and detect the working state and operation of the intelligent controller itself;
□ With pre-alarm indication and overload indication: when the load current reaches or exceeds the setting value, the light guide column will lead out the light source;
□ Dual air gap technology of magnetic flux converter: more reliable and stable operation, no misoperation, reliable tripping and low power;
□ High protection accuracy: overload protection, short circuit short delay protection action current accuracy ± 10%; The accuracy of short-circuit instantaneous protection value is ± 15% depending
on the action current;
□ Interchange ability of installation: the overall dimensions and installation dimensions are the same as those of RDM1 series plastic case circuit breaker.
□ Dual passive signal output function: for signal (or alarm), with capacity of AC230V3A;
□ With fire shunt function: overload alarm does not trip (a pair of passive contacts are provided) and shunt trip function is provided;
