DW17-2900 Circuit Breaker Product Introduction (English)
The DW17-2900 series frame circuit breaker is engineered for DC220V power systems, incorporating advanced electrical rapid-fix vertical operation technology. With a rated current of 2000A, this device delivers reliable circuit protection against overload and short-circuit conditions, particularly suited for demanding DC distribution applications requiring enhanced operational efficiency and safety assurance.
Three core technological advancements define its performance: The modular architecture optimizes internal component layout, achieving IP40 protection rating while maintaining proper electrical clearances. Its intelligent electric actuator employs linear drive technology, enabling 15ms closure response time combined with dual-break arc extinguishing system to contain arc discharge. The integrated mechanical interlock and multi-state indication system allows visual contact position monitoring through observation windows, facilitating maintenance verification without specialized tools.
Specialized protection mechanisms include real-time thermal monitoring and fault pre-alert functions. Upon detecting abnormal temperature rise or potential failure risks, the system activates tiered warning levels while logging event parameters for maintenance analysis. The silver-alloy contact system with multi-point pressure equalization maintains stable contact resistance through 10,000 mechanical endurance cycles.
Typical applications span renewable energy plants, rail traction power networks, and industrial automation centers. In photovoltaic DC combiner boxes, it effectively suppresses reverse current surges, while in electrified railway systems ensures rapid fault isolation for power continuity. The unit supports both horizontal and vertical mounting orientations, with passivated enclosure surface accommodating operational temperatures from -25℃ to +70℃.
This breaker features tool-free adjustment for trip parameters and detachable control units, significantly reducing field service time. Optional communication modules enable remote status monitoring through standard interfaces. The optimized magnetic blowout design minimizes arc energy during interruption, while vibration-resistant construction ensures stable performance in dynamic environments.
