Product Overview
The DW17-1900 630/630 electric quick-fix vertical AC220V frame circuit breaker is a high-performance power distribution protection device designed for AC 50Hz networks with rated voltages from 400V to 690V. Featuring a modular cube structure, it integrates key components including frame, contact system, arc extinguishing chamber, trip unit and operating mechanism. With rated current of 630A and control power supply of AC220V, it provides reliable power distribution while protecting circuits and equipment against short-circuit, overload and under-voltage faults. The product supports flexible protection configuration through combination of long-time delay, short-time delay and instantaneous trip functions. 1416
Technical Features
This circuit breaker adopts electric quick-make/quick-break operating mechanism that ensures fast and stable switching operations with extended mechanical durability. Its advanced arc quenching system enables rapid interruption of fault currents to maintain power system safety. The silver-alloy contacts demonstrate low resistance and excellent arc resistance. With front-mounted vertical wiring and withdrawable design, the product allows convenient installation and maintenance. It maintains stable performance in harsh environments from -5℃ to +40℃ at altitudes below 2000 meters, suitable for diverse industrial applications. 3619
Application Scenarios
The DW17-1900 frame breaker is widely used in industrial power distribution systems, commercial building power networks and main circuit protection for heavy equipment. It proves particularly effective in scenarios requiring frequent operations and high breaking capacity, such as power plants, substations and petrochemical facilities. For motor protection applications, it provides reliable overload and short-circuit protection for motors up to 630A, while supporting occasional starting operations. Its superior protective performance makes it an ideal choice for primary circuit protection and critical load protection in power distribution systems. 4912
