CDW3-2000N/800A 4P Intelligent Frame Circuit Breaker Technical Description
I. Product Overview
The CDW3-2000N/800A 4P intelligent air circuit breaker adopts drawer-type horizontal installation design, suitable for AC 50Hz distribution networks with rated operational voltage AC230V. Integrating protection, control and measurement functions, this product supports comprehensive voltage monitoring capabilities to effectively implement under-voltage protection. Modular structural design facilitates equipment maintenance, while compact dimensions accommodate various switchgear installation requirements.
II. Core Features
-
Intelligent Voltage Management
Equipped with precision voltage sensors for real-time system monitoring. When line voltage drops below AC230V threshold, staged protection activates within 0.1-3s adjustable delay range, preventing equipment damage from under-voltage operation. Protection parameters are digitally configurable via HMI.
-
Drawer-type Mechanism
Innovative rail-sliding mechanism enables quick plugging/unplugging of main unit. The operating handle features clear three-position indicators (ON/OFF/Isolation). Mechanical interlock prevents drawer removal during energization. Modular design reduces maintenance time by over 40%.
-
Multi-protection Integration
Combines three-stage protection characteristics (overload long-delay, short-circuit short-delay, instantaneous trip) with voltage monitoring for comprehensive protection. Dual-element tripping mechanism (bimetal strip + electromagnetic release) ensures precise operation timing.
-
Human-Machine Interface
Rotary parameter knobs with 5-digit LED display enable real-time monitoring of current/voltage parameters. Memory function retains user settings during power loss. Red mechanical trip indicator provides instant status feedback.
III. Typical Applications
Designed for industrial plant distribution systems, commercial building main switchboards, and data center power distribution units. Particularly suitable for power supply environments with voltage fluctuation risks, providing reliable protection for motor sets and transformers.
IV. Structural Design
AgNi alloy contacts with 4-pole synchronous breaking technology ensure rapid arc extinction. Arc chute with multi-splitter structure delivers superior breaking capacity. Terminals accept 25-240mm² conductors with torque-indicating bolts. Operating mechanism maintains stable performance through 20,000 mechanical endurance tests.
