The HMT3C series intelligent molded case circuit breakers (intelligent IoT circuit breakers) are products developed specifically for the ubiquitous power IoT, offering current ratings from 125A to 800A. They represent an innovative application of artificial intelligence technology in on-site operations within the power industry.

It features small size, convenient installation and use, adjustable fixed action values in different levels, and simple operation. It is suitable for the Internet of Things, a network system that realizes the identification, perception, interconnection, and control of power grid infrastructure, personnel, and the surrounding environment. Essentially, it is the integration of various information sensing devices with communication information resources (Internet, telecommunications network, and even dedicated power communication network), thereby forming physical entities with self-identification, perception, and intelligent processing capabilities.

The communication standard is applicable to and meets the various intelligent requirements of smart grid management, especially suitable for comprehensive protection at all levels of the grid, and is the preferred product for supporting the operation of the national smart grid. Focusing on all aspects of the power system, it fully utilizes modern information technologies such as mobile internet and artificial intelligence, as well as advanced communication technologies, to achieve interconnection of all things and human-machine interaction in all aspects of the power system. It is a smart service system featuring comprehensive state perception, efficient information processing, and convenient and flexible application, consisting of a four-layer structure: perception layer, network layer, platform layer, and application layer.

The smart IoT circuit breaker, in addition to its original functions, now offers the following new features: instantaneous active power, instantaneous reactive power, instantaneous power factor, and electric quantity.

Online monitoring:

With 24-hour online monitoring, you can quickly view various electrical indicator information of power lines, such as voltage, current, power, temperature, and leakage current. In case of anomalies, the system automatically identifies problematic lines, accurately identifies potential safety hazards, eliminates operational blind spots, and ensures safety and peace of mind.
Remote control:

Remote control of electrical circuits can be achieved through various means such as local area networks and the Internet, with each circuit being turned on or off as needed.

Scheduled tasks:

Set the time for each line to be turned on or off, which can be set as a one-time task or a recurring task.

Electricity statistics:

Conduct statistical analysis on the electricity consumption of electrical equipment to examine the composition of electricity usage. Perform year-on-year and month-on-month comparisons, display graphical representations of electricity consumption trends, gain a comprehensive understanding of electricity usage, and enhance energy utilization efficiency.

Alarm information: It can monitor and analyze multiple electrical safety hazards such as leakage, overload, short circuit, and abnormal cable temperature, accurately locate electrical fire hazards, customize and push safety pre-alarm information, and achieve prevention before ignition.

Carrier-based product: The product features carrier communication for upstream transmission and micro-power wireless communication for downstream transmission, and achieves self-organizing network functionality with the intelligent leakage monitoring miniature circuit breaker under the meter.

It features a variety of local interfaces, including RS-485, infrared communication, and micro-power wireless communication interfaces; it enables remote control, allowing for intelligent functions such as remote opening, closing, and querying of operating status.

The intelligent residual current operated circuit breaker is equipped with the capability to collect and transmit data such as voltage, current, electric quantity, and power. The measurement accuracy for current and voltage is not lower than 0.5S level, the active measurement accuracy is not lower than level 1, and the reactive measurement accuracy is not lower than level 2. The HPLC communication unit supports interconnection and interoperability
