Series Overview

DW45 Series Intelligent Universal Circuit Breaker

Scope of Application

The DW45 Series Intelligent Universal Circuit Breaker (hereinafter referred to as "the circuit breaker") is suitable for power distribution networks with AC 50Hz, rated operational voltage of 400V/690V, and rated current from 630A to 6300A. It is primarily used for power distribution, feeder protection, and generator protection, safeguarding lines and power equipment against overload, undervoltage, overvoltage, current/voltage imbalance, short-circuit, and grounding faults. Through load monitoring and zone interlocking functions, it ensures rational operation of the power grid. It also measures grid parameters such as current, voltage, power, frequency, energy consumption, demand, and harmonics at grid nodes. The circuit breaker can directly protect motors and generators against overload, undervoltage, and short-circuit faults.

Equipped with an intelligent controller, the circuit breaker provides precise selective protection to avoid unnecessary power outages, enhancing power supply reliability, continuity, and safety. It may include an open communication interface to achieve "four remote functions" (telemetry, telecommand, remote control, and remote adjustment), meeting requirements of control centers and automation systems.

When the intelligent controller and current transformers are removed, this series can function as an isolator.

The circuit breaker supports both top and bottom cable entry, making it suitable for power stations, factories, smart buildings, and other low-voltage distribution applications. It can also serve as an infrequent starter for motors.

● Compliance Standards: GB/T 14048.2 Low-voltage switchgear and controlgear – Part 2: Circuit breakers.
