Product Overview
The DW17-3900 3200A 3P Fixed-Type Quick-Acting Vertical AC220V Main Circuit Accessory is an intelligent frame circuit breaker designed for high-current power distribution networks. Featuring a three-dimensional layout with insulated framework, it integrates contact systems and operating mechanisms, supporting both rapid electric operation and manual control. Suitable for 50Hz AC systems with rated voltages of 400V/690V, its primary functions include power distribution, line protection, and safeguards against overload, short-circuit, and under-voltage conditions. The modular design ensures adaptability to diverse application requirements.110
Key Features
With a modular architecture, this breaker separates contact systems from arc-extinguishing units to enhance breaking efficiency. Main circuit accessories include undervoltage and shunt trip devices, compatible with AC220V control power. It supports quick-acting fixed vertical (electric-fast-fixed-vertical) operation and manual energy storage. The metal frame houses intelligent trip units and current sensors for real-time load monitoring, enabling multi-stage protection (e.g., overload long-delay, short-circuit short-delay). Drawer-type and fixed mounting options cater to varied panel layouts.21317
Technical Specifications
