RDM5E series electronic molded case circuit breaker. The circuit breaker is applicable to the distribution network with AC 50Hz, rated insulation voltage of 1000V, rated working voltage of 690V and below, and rated working current of 800A and below. It is used to distribute electric energy and protect the line and power supply equipment from overload, short circuits, Undervoltage, and other faults. 
RDM5E series Circuit breaker with a rated current of 630A and below. It can also be used to protect the motor. Under normal conditions, the circuit breaker can be used for infrequent line switching and infrequent motor starting. 
RDM5E series circuit breaker has the functions of overload long time delay inverse time limit, short circuit short time delay inverse time limit, short circuit short time delay definite time limit, short circuit instantaneous and under voltage protection, which can protect the route and power supply equipment from damage. 
The product conforms to IEC60497-2/GB/T14048.2 standard.


Application
1.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; 
2. 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); 
3. Large current instantaneous tripping function: when the circuit breaker is closed and running, in case of a 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; 
4. With tripping test (test) function: input DC 12V voltage to test the action characteristics of a circuit breaker; 
5. Fault self-diagnosis function: protect and detect the working state and operation of the intelligent controller itself; 
6. 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; 
7. Dual air gap technology of magnetic flux converter: more reliable and stable operation, no misoperation, reliable tripping, and low power; 
8.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; 
9. Interchangeability of installation: the overall dimensions and installation dimensions are the same as those of the RDM1 series plastic case circuit breaker. 
10. Dual passive signal output function: for signal (or alarm), with a capacity of AC230V3A; 
11. With fire shunt function: overload alarm does not trip (a pair of passive contacts are provided) and shunt trip function is provided;
12. Communication function: standard RS485, Modbus field bus protocol;
