Product Introduction
The DW17-2900 2000/2000 Fixed Horizontal AC380V Frame Circuit Breaker is a high-performance electrical protection device designed for AC power distribution networks. With rated operational current of 2000A, it operates reliably in 50Hz 380V circuits to distribute electrical energy and protect circuits against overloads, under-voltage and short circuits. The horizontal fixed mounting style combined with electric quick-make/quick-break mechanism ensures convenient operation. Its robust construction guarantees stable performance within ambient temperatures from -5℃ to +40℃ at altitudes up to 2000 meters. 612
Technical Features
This breaker adopts modular design with insulated housing, contact system and operating mechanism as core components. The electric quick-operating mechanism (AC380V control voltage) enables rapid switching. Three-stage protection characteristics (long-time delay overload, short-time delay and instantaneous protection) provide flexible configuration options. Horizontal wiring facilitates cabinet layout while fixed structure simplifies installation. The air-type arc extinguishing system ensures reliable interruption of fault current. The electromagnetic operating coil maintains stable performance within 85%-110% of rated voltage range. 713
Application Fields
Ideal for primary distribution in industrial power systems, this frame breaker is widely used in substations, factory workshops and commercial buildings. As main switch, it protects transformers and busbars; as branch switch, it safeguards high-capacity electrical equipment. The compact design suits space-constrained panels, while electric operation supports remote control for automated distribution. Particularly suitable for applications requiring frequent operation or fast fault interruption, such as motor control centers and large-scale lighting systems. 815
