series Intelligent type universal circuit breaker Appliance RDW1-1000 air circuit breaker, applied to power distribution network of AC50Hz, Rated voltage 400V (or 380V), Rated current from 200A to 1000A. It is mainly used to distribute electric power and protect the circuit and equipments against damages of overload, short-circuit, under-voltage and phase contact with ground this kind fault. And it also be used for circuit transfering, motor starting unfrequently and protection. This production has various intelligent protection functions, provides accurated selective protection, improves power-supply reliability to aviod unneccessary power interruption. It has isolation functions, sign is " ". This production 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 2.1.1 Use type: A type for unselective type, B for selective 2.1.2 Installation type: Fited-type, draw-type 2.1.3 Transmission type: Motor type, handle type 2.1.4 Poles: 3P 4P 2.1.5 Release type: Intelligent controller, shunt release, under-voltage instantaneous release(or delay release) 2.1.6 Intelligent controller type ST450-2L for economic type(basic function) ST450-3M for basic type(basic function+Intelligent function) ST450-3H for advanced type(basic function+Intelligent function+communication port) Normal operation conditon and installation condition 3.1 Temperature: no more than +40ºC, no less than -5ºC, and average day temperature no more than +35ºC. Notice: when the temperature requirment exceed the above range, it should be consulted with Manufacture. 3.2 Atitude: Installation location altitude should no more than 2000m. 3.3 Humidity: when the temperature at +40C, it no more 50%. The higher humidity is acceptd at the lower temperature. The condensetion should be taken care when the humidity chanage.
