Air-operated circuit breaker RDW1 series

under-voltagepoweroverload

RDW1 air circuit breaker which applied to power distribution network of AC 50/60Hz, rated operational voltage up to 690V, rated current up to 6300A. It's mainly used to distribute power and protect the circuit and equipments against damages of overload, short-circuit, under voltage and ground fault, and it has intelligent protection functions, provides accurated selective protection, improves power-supply reliability to avoid unnecessary power interruption. And it also has open type communication port, can realize remote control function and satisfy the requirements of control center and automatic system. This production without intelligent controller and senor has insulation function. This product conforms to the standard of IEC60947-2 Normal opération condition and installation condition 3.1 - Temperature: no more than +40*0,no less than-St, and average day temperature no more than +35^. If customer requires condition of higher than +4013,or lower than -25<\3,it should be consulted with manufacture. 3.2 - Installation location attitude no more than 2000m 3.3 - Humidity: when the temperature at +40*0, 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^. The condensation should be taken care when the humidity change. 3.4 - Protection class: IP20 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.
