Product Overview
The DW17-3900 3900A universal circuit breaker is a high-performance power distribution protection device designed for 50Hz AC networks with 380V/660V voltage or 440V DC systems. Featuring motorized pre-charged operating mechanism powered by DC220V and non-undervoltage protection function, it is ideal for current distribution and circuit protection in high-current systems. The unit provides reliable protection against overload and short-circuit faults while enabling infrequent circuit switching under normal conditions. Its robust frame-type construction ensures mechanical durability, with both withdrawable and fixed versions available for flexible installation.467
Key Features
Equipped with intelligent tripping technology, the breaker monitors real-time current status through electronic sensors for precise overload and short-circuit protection. Silver-alloy contacts combined with arc chute design effectively suppress arcing and extend service life. The motorized pre-charged mechanism enables rapid closing via DC220V power supply with short response time, maintaining energy storage without continuous power supply. Withdrawable version features handle-operated interface and three-position indication (connected/test/disconnected) for convenient maintenance. Modular design allows expansion up to 12 auxiliary contacts for secondary circuit control requirements.51824
Technical Specifications
Rated current reaches 3900A with breaking capacity of 65kA (RMS), mechanical endurance exceeds 10,000 operations. Suitable for altitudes below 2000m and ambient temperatures from -5℃ to 40℃ with IP00 protection grade. Special alloy contact pressure springs ensure stable resistance after prolonged use. Arc extinguishing system combines forced air cooling and metal grid separation for zero arc emission safety. The control panel integrates close/open buttons, energy storage indicator and manual operation handle following ergonomic principles.7812
Applications
This product is widely used in industrial power systems, large commercial buildings and critical infrastructure for main circuit protection. Particularly suitable for metallurgical, chemical and data center applications requiring high-reliability distribution, it effectively prevents equipment damage caused by overcurrent or short circuits. The withdrawable design facilitates maintenance without power interruption, while optional smart controller enables remote monitoring and fault logging.41116
