Product StructureRDQ3-63-A/B/C/D series ATS comprised with two MCB and accessories, mechanical interlock system, intelligent controller etc. Product have A, B,C,D four type control construction, A type is basic type ( Only provide with auto change auto recovery, phase missing protect, auto/manual control), B type is intelligent type( including the A type functions and have Generator start, fire linkage, time delay functions), C and D type is improved type, increased three phase voltage monitoring function on A and B type. This ATS series circuit breaker keeps the original breaker's overload and short circuit protection function. RDQ3NX Series Advantages:1. Product with modularized design, executive unit, transmission mechanism, control circuit completely independent, easy for replacement. 2. Mechanical transmission device adopt gear transmission, completely eliminate the possibility of closing at same time; 3. Compact appearance, it is one of the smallest product on the market; 4. The control circuit layout adopt working power and sampling power separate with single chip control, to overcome the electromagnetic interference from the hardware construction; 5. Working power voltage range: AC200-400V; 6. Less power consumption, max. peak power loss 4.8W, only 20% of other similar products; 7. Product have complete functions, with generator start, fire linkage, ON delay functions etc.; 8. Modularized design, good components interchange performance, easy installation; 9. Can use various executive circuit breaker;  Working ConditionsAmbient Temperature Max. +60ºC Min. -20ºC 24h average not more than +35º
