CDW3-1600N 400A3P Intelligent Frame Circuit Breaker
The CDW3-1600N 400A3P is an advanced drawer-type frame circuit breaker engineered for modern power distribution systems. Designed for 50Hz AC networks with operational voltages up to AC400V, this 400A-rated three-pole device delivers reliable protection for industrial power distribution, commercial complexes, and large-scale equipment supply systems.
Key Features:
-
Multi-stage Protection System
Equipped with precision electronic trip unit integrating three-stage protection: long-time delay overload, short-time delay short circuit, and instantaneous short circuit protection. User-configurable threshold settings adapt to voltage environments from AC230V to AC380V through digital interface.
-
Drawer-type Innovation
Horizontal sliding mechanism enhances maintenance efficiency through full-guided roller contact system. Hot-swappable operation capability allows live insertion/extraction. Independent isolation contacts ensure complete circuit disconnection during servicing.
-
Intelligent Monitoring
LCD display provides real-time monitoring of current, voltage, and fault parameters. Event recorder stores last 10 tripping incidents with timestamps for system diagnostics. Automatic self-test routine verifies protection functionality periodically.
-
Environmental Resilience
Silver-plated contacts with multi-chamber arc extinguishing structure maintain stable performance under harsh conditions (up to 95% humidity, 2000m altitude). Mechanical interlocking prevents improper racking operations.
Typical Applications:
- Main power intake protection for industrial plants
- Floor distribution systems in commercial complexes
- UPS input/output circuits in data centers
- Power distribution units for port machinery
