RDW5 Series Intelligent Frame - type Circuit Breaker

Designed for low - voltage power distribution systems, our RDW5 Series Intelligent Frame - type Circuit Breaker integrates advanced intelligent control technology with a sturdy structural design. Ideal for power distribution networks in power stations, factories, smart buildings and other scenarios, it safeguards distribution lines, feeders and power generation equipment. It protects circuits and power supply devices from hazards such as overload, under - voltage, over - voltage, current - voltage imbalance, short - circuit, and grounding/leakage faults. The series of circuit breakers supports both top - entry and bottom - entry wiring. It is applicable to various low - voltage power distribution fields and can also be used for the infrequent starting of motors.

Key Features

1. Comprehensive Protection Modes

• Overload & Short - circuit Protection: Utilizes high - precision current sensing components. When overload (≥1.05 times rated current) or short - circuit (up to dozens of times rated current) occurs, it trips within milliseconds. Effectively prevents line overheating and equipment damage, with protection accuracy reaching ±3%, minimizing power distribution safety risks.

• Under - voltage & Over - voltage Protection: Monitors line voltage in real - time through voltage detection modules. When the voltage is lower than 85% of the rated voltage (under - voltage) or higher than 115% of the rated voltage (over - voltage), it automatically disconnects. Ensures stable operation of sensitive electrical equipment and avoids damage caused by voltage fluctuations.

2. Intelligent Control & Monitoring

• Automatic Operation: Equipped with a microprocessor - based intelligent control unit. It analyzes real - time current, voltage, and load data of the circuit, and automatically adjusts protection parameters. Realizes adaptive protection for different loads, such as reducing tripping sensitivity for motors during startup to avoid misoperation.

• Remote Monitoring & Management: Supports communication interfaces like RS485 and Modbus. Connects to power distribution monitoring systems (SCADA). Remotely monitors key parameters (e.g., contact temperature, trip status, load current), and sends fault alarms (such as overload alarms, short - circuit alarms) in real - time. Facilitates centralized management and predictive maintenance of power distribution systems.

3. Flexible Wiring & Installation

• Dual - direction Wiring: Allows both top - entry and bottom - entry wiring methods, adapting to different power distribution cabinet layouts and on - site installation conditions. Reduces wiring restrictions and improves installation efficiency.

• Modular Design: The circuit breaker adopts a modular structure, including the main body, intelligent control module, and protection module. Facilitates function expansion (such as adding leakage protection modules) and maintenance replacement. Modules can be quickly disassembled and assembled, reducing maintenance time.

4. High Reliability & Durability

• Strong Mechanical Structure: Uses high - strength insulating materials and reinforced mechanical linkage mechanisms. Withstands mechanical impacts during frequent switching and short - circuit conditions, ensuring stable operation. The mechanical service life reaches tens of thousands of times, meeting long - term use needs.

• Low - loss & Energy - saving: Optimizes the contact system and arc - extinguishing structure. Reduces contact resistance and arc - extinguishing energy consumption, lowering no - load loss by about 20% compared to traditional frame - type circuit breakers. Complies with international and domestic low - voltage electrical energy - saving standards.

Technical Specifications

Applications

• Industrial Power Distribution: In factories, steel plants, and petrochemical enterprises, it serves as the core protection device for low - voltage power distribution systems. Protects large - scale equipment (such as motors, transformers) and power distribution lines, ensuring continuous production.

• Commercial & Smart Buildings: In shopping malls, office buildings, and smart industrial parks, it is used for power distribution management in low - voltage power distribution rooms. Maintains stable power supply for lighting, air - conditioning, and office equipment, and supports intelligent power management systems.

• Power Generation & Energy Storage: In small power plants, distributed generation projects (such as diesel generator sets), and energy storage systems, it provides over - current, over - voltage, and other protection functions. Ensures safe operation of power generation and energy storage equipment and stable connection to the grid.
