series Intelligent type universal circuit breaker Appliance RDW1-2000~6300 air circuit breaker, applied to power distribution network of AC50Hz,rated operational voltage up to 690V,Rated current from 400A to 6300A. It is mainly used to distribute powerand protect the circuit and equipments against damages of overload, short-circuit,undervoltage and ground fault. And it has Intelligent protection functions, provides accurated selective protection,improves power-supply reliability to aviod unneccessary power interruption. And it also has open type communication port,can realize remote control function and satisfy the requirments of control center and Automatic system. This production without Intelligent controller and senor has insulation function, the sign is . This protection conforms to the standard of GB14048.2 and IEC60947-2. Poles Controller type Frame size rated current C for drawout-type, non for fited-type Design code Air circuit breaker Company code 2.1 Release type Intelligent controller, Undervoltage instantaneous(or delay)release, Shunt release. 2.2 Intelligent controller function a) Intelligent control: H type(for Communication), M type(for Normal), L type(for economic) b) It has Overload long-time delay inverse time-limit, short-time delay inverse time-limit, constant time-limit, Instantaneous tripping function. The protection characteristic can be constituted to meet curtomers owned requirements. c) Single phase ground fault protection function d) Indication function:Setting current indication, Action indication, Voltage of each line indication e) Alarm indication: overload alarm f) self inspection function: over heat self-inspection, micro-computer inspection g)Testing function: test action characteristic of controller Normal operation conditon and installation condition 3.1 Temperature: no more than +40C, no less than -5C,and average day temperature no more than +35C. If customer requires condition of higher than +40C,or lower than -25C, it should be consulted with manufacture. 3.2 Installation location atitude no more than 2000m.

3.3 Humidity: when the temperature at +40°C, it no more 50%. The higher humidity is accepted at the lower temperature. The average humidity of month should no more than 90%,and the average temperature of month should not lower than +25°C. The condensetion should be taken care when the humidity chanage. 3.5 Using type:B type 3.6 Pollution type: 3 level 3.7 Installation type: Type of circuit breaker main circuit, under-voltage release, primary coil of power transformer is Installation IV; type of Auxiliary circuit and control circuit installation is III. ^ Technical data and performance 4.1...

4.3.3 Long-time delay overcurrent protection inverse time-lag characteristic , action time see Table 4, time error is ±15%. Note: t -setting time of longtime delay 1.5I 1, T -action time of longtime delay action time. 4.3.4 short-time delay overcurrent protection characteristic This protection is constant time-lag, if it requires the low multiply is inverse time-lag, the characteristic following: I2Ts=(8Ir1)2ts , ts is normal delay setting time; when overload current > 8Ir1, it would transfer to inverse time-lag automatically, see Table 5, and time-error is ±15%. Table 5 Delay...
