Acrel ASCB Smart Mini Circuit Breaker: Double The Efficiency of Power Distribution Operation And Maintenance

Background

The safety and intelligence of low-voltage terminal power distribution are directly related to the stable power supply in various scenarios such as construction and industry. With the country putting forward higher requirements for the safety protection and intelligent monitoring of low-voltage power distribution systems, traditional circuit breakers that can only realize basic switching operations can no longer meet the refined operation and maintenance needs of modern scenarios.

Are You Facing These Power Distribution Pain Points?

• Hidden hazards are difficult to detect: Traditional air switches lack real-time monitoring functions. Risks such as overvoltage, overload, and leakage are invisible and hard to capture through manual inspections, which may easily lead to safety accidents;

• Low fault location efficiency: After a fault occurs, it is necessary to check each circuit one by one, which not only takes time for maintenance but also causes significant downtime losses;

• Delayed emergency response: Only local manual operation is supported. In night or unattended scenarios, sudden faults cannot be handled quickly, which may easily lead to the expansion of faults;

• High cost of transformation and upgrading: There are many terminal circuits and limited installation space. Traditional intelligent transformation requires rewiring, which is cumbersome and costly.

Full-Core Functions to Fully Protect Power Safety

Incoming Circuit: Smart Power Online Monitoring + Outgoing Circuit Arc Fault Monitoring + Early Warning

• Monitoring function: Real-time monitoring of leakage, temperature, voltage, current, power, electrical energy, and other parameters of the main circuit, as well as arc monitoring of the outgoing circuit.

• Alarm function: Overvoltage alarm, undervoltage alarm, overcurrent alarm, overload alarm, leakage alarm, overtemperature alarm, three-phase missing phase alarm, arc alarm, etc.

Outgoing Circuit: Intelligent Mini Circuit Breaker

• Monitoring function: Real-time monitoring and reporting of electrical parameters such as voltage, current, power, electrical energy, leakage, temperature, and frequency.

• Alarm function: Overvoltage alarm, undervoltage alarm, overcurrent alarm, overload alarm, leakage alarm, overtemperature alarm, three-phase missing phase alarm, etc.

• Protection function: Overvoltage protection tripping, undervoltage protection tripping, overcurrent protection tripping, overload protection tripping, short-circuit protection tripping, leakage protection tripping, overtemperature protection tripping, three-phase missing phase protection tripping.

• Control function: Supports various control functions such as local handle on/off, local electric switching, local locking, remote control switching, timing control, and preset control.

Key Function Highlights

• Real-time monitoring of all parameters: Captures key data such as voltage, current, power, electrical energy, and temperature. The leakage model additionally supports leakage monitoring, enabling 24/7 grasp of the circuit operation status to detect and handle hidden hazards early;

• Comprehensive multiple protections: Equipped with basic protections such as overvoltage, undervoltage, overload, short circuit, and overtemperature. The leakage model adds leakage protection (default 20mA early warning, 30mA tripping, adjustable threshold). Automatic tripping is triggered when indicators exceed standards to avoid fault expansion;

• Flexible and convenient multiple controls: Supports local manual push rod, electric control, and locking functions, combined with remote control and timing control. Even in unattended scenarios, emergency situations can be responded to quickly, and remote power cutoff reduces risks;

• Intelligent alarm and traceability: In case of failure, indicators (red light flashing to distinguish early warning, alarm, and fault status) prompt in a timely manner. Combined with the smart power consumption cloud platform, alarm information can be synchronously received on mobile phones and web terminals to locate the faulty circuit.

Distinctive Advantages to Double Operation and Maintenance Efficiency

• Easy installation and low cost: Adopts standard 35mm DIN rail installation, with 1:1 width replacement with traditional air switches (1P is only 18mm, 4P is only 72mm). No additional wiring modification is required, the construction is simple, and the transformation cost is greatly reduced;

• Upgraded performance and higher reliability: The frame grade reaches 80A, supporting a maximum rated current of 80A (most peers are 63A) to meet higher load requirements; Type A leakage protection covers Type AC functions, which can monitor pulsed DC leakage and provide more comprehensive protection; The mechanical life is 20,000 times, and the electrical life is 6,000 times, which is stable and durable;

• Flexible networking and communication: Standard RS-485 (MODBUS) communication, which can be networked with intelligent gateways, supporting multiple communication modes such as 485, Ethernet, 4G, and WiFi. Data is synchronized to the cloud platform to achieve real-time monitoring on multiple terminals;

• Adaptable to multiple scenarios: The operating temperature range is -10℃~55℃, and the protection grade is IP20. It can operate stably in industrial, commercial, civil buildings, and other scenarios without explosion hazards and conductive dust, and is applicable at altitudes ≤2000m.
