In a modern industrial park in Riyadh, Saudi Arabia, Fahad, a professional electrical engineer, frowned while staring at the central control screen. This large integrated park covering manufacturing, logistics and new energy supporting facilities was trapped in severe power distribution troubles. Affected by persistent extreme high temperatures and drastic power grid load fluctuations in Saudi Arabia all year round, the original traditional circuit breakers frequently failed in overload protection and delayed short-circuit breaking. These hidden dangers not only caused unexpected production line shutdowns and huge economic losses, but also kept the entire park’s power supply system under long-term operational risks.
Furthermore, conventional power distribution equipment lacked remote monitoring functions, requiring 24-hour on-site inspection by operation and maintenance teams. This outdated management mode brought low work efficiency and high labor costs. Once a circuit fault occurred, maintenance staff could not quickly locate and resolve the problem in time.
As the person in charge of the park’s power distribution system upgrading project, Fahad was seeking a high-performance air circuit breaker that could adapt to harsh desert environments, deliver comprehensive protection and support intelligent digital management. It needed to meet the high-current power distribution demands of heavy industry while realizing automatic remote monitoring and operation. After strict screening, on-site testing and comprehensive comparison with multiple brands, the RDW5 Series Intelligent Type Air Circuit Breaker (ACB) launched by PEOPLE ELECTRIC stood out as the final solution.
Since its official commissioning, the failure rate of the park’s power distribution system has dropped sharply. Its integrated intelligent monitoring and multi-dimensional protection functions perfectly adapt to the harsh operational requirements of Saudi industrial scenarios. This high-quality power distribution equipment manufactured in China has completely solved the long-standing power supply bottlenecks for local industrial users and delivered a reliable answer to safe and efficient power distribution in the Middle East.
Today, we will conduct an in-depth and comprehensive introduction to the RDW5 intelligent air circuit breaker, which is widely recognized by global industrial customers, and analyze why it has become a preferred core protection device for overseas high-end power distribution projects.
1. Product Positioning & Application Scenarios
The RDW5 Series Intelligent Air Circuit Breaker (ACB) is a core power distribution equipment independently developed by PEOPLE ELECTRIC. It is designed for power distribution networks with AC 50/60Hz, rated operational voltage up to 400V/690V and rated current up to 6300A. It is highly compatible with mainstream application scenarios in Saudi Arabia and other Middle Eastern regions, including large industrial plants, data centers, power grid hub stations, commercial complexes and key municipal engineering projects.
Beyond basic circuit connection and disconnection, this ACB can reasonably distribute electric energy and provide all-round protection for power circuits and electrical equipment. It effectively avoids equipment damage and safety accidents caused by overload, undervoltage, short circuit, single-phase grounding and other circuit faults. With excellent insulation performance and environmental adaptability, it serves as an indispensable safety guardian for medium and high-voltage power distribution systems.
2. Core Technical Parameters: Full-Coverage for Diverse Power Distribution Demands
The RDW5 product line includes complete specifications: RDW5-1600, 2000, 2500, 3200, 4000 and 6300. The rated current ranges from 200A to 6300A, fully covering power supply demands from small distribution rooms to large-scale industrial parks. All technical indicators strictly comply with the international standard IEC60947-2, ensuring global recognized quality and safety performance.
Basic Core Parameters
| Parameter | Specification |
| Rated Operational Voltage | AC 400V/690V |
| Rated Frequency | 50/60Hz |
| Pole Number | 3P / 4P Optional |
| Rated Impulse Withstand Voltage | 12kV |
| Rated Insulation Voltage | 1000V |
| Power Frequency Withstand Voltage (1min) | 3500V |
| Short-Circuit Breaking Time | 25-30ms (No auxiliary delay) |
| Closing Time | ≤70ms |
Short-Circuit Breaking Capacity (Key Safety Index)
The series is divided into two versions: S-type (Standard Type) and H-type (High Breaking Capacity Type). Under AC 400V and 690V working voltage, the ultimate short-circuit breaking capacity (Icu) reaches up to 135kA. Meanwhile, the operational short-circuit breaking capacity (Ics) and short-time withstand current (Icw) maintain leading industry levels. Faced with extreme short-circuit faults, it can cut off the circuit instantly to stabilize power supply, perfectly coping with high load and high-risk power grid operating conditions in Saudi Arabia and surrounding regions.
3. Multi-Layer Intelligent Protection: Preventing All Kinds of Circuit Faults
The biggest highlight of the RDW5 series lies in the integrated design of multi-dimensional physical protection and intelligent digital control, which makes up for the defects of single protection and slow response of traditional circuit breakers.
①Comprehensive Fault Protection
Equipped with complete protection functions including overload protection, undervoltage protection, short-circuit protection and single-phase grounding protection. It covers almost all common circuit faults in industrial power distribution to protect lines and electrical equipment in an all-round way.
②High-Precision Intelligent Controller
Built-in high-performance intelligent controller supports dual operation modes: inverse time limit and definite time limit. When abnormal current occurs, the action time will be automatically adjusted according to the fault current magnitude. It effectively prevents false tripping caused by slight current fluctuation and ensures rapid breaking under severe fault conditions, achieving more accurate and humanized protection.
③High-Grade Insulation Performance
Adopting high-quality insulating materials and optimized structural design, it features strong anti-breakdown and anti-leakage capabilities. It stably operates in high-temperature, dusty and harsh industrial environments, with far better durability than ordinary circuit breakers.
4. Intelligent Communication & Remote Control: Adapt to Automated Power Distribution Systems
To meet the upgrading demand of modern industry for automation and intelligent management, the RDW5 series realizes networked intelligent control, which is the core reason for its wide application in Saudi smart industrial parks.
● Support two-way communication between multiple circuit breakers and central control systems. Operation and maintenance personnel can remotely view real-time operating data such as current, voltage and fault alarms without on-site inspection.
● Enable remote closing, remote opening, electric energy storage and remote fault reset. Emergency circuit cutting and fault handling can be completed in the control room to minimize production downtime losses.
● It can be seamlessly connected with smart power distribution systems, smart factory platforms and smart grid solutions to realize full-process digital management of power distribution.
5. Optimized Structural Design: Flexible Installation, Durable & Safe
The RDW5 series adopts a modular integrated structure, balancing practicality, cost performance and operational safety, with humanized details tailored for global overseas users.
①Cost-Effective & DurableCore components are made of high-strength and high-temperature resistant materials to reduce long-term failure rate and later maintenance costs.
