Industrial Internet of Things (IIoT):The smart circuit breaker has a built-in current/temperature sensor to monitor the power status of the equipment in real time and provides early warnings of overload and short circuit risks through a cloud platform, helping factories to achieve predictive mainten

Photovoltaic power plants and energy storage systems:

Miniature circuit breakers (MCBs) are used in inverter protection circuits. Their high-temperature resistant design adapts to extreme outdoor environments, and their intelligent tripping function prevents DC arc fires.

Wind turbine generator sets:

Molded case circuit breakers are certified to IP66 protection level, resisting salt spray corrosion and strong vibration, ensuring the safe operation of offshore wind power platforms.

Green building and smart cities:

Smart home system: The miniature circuit breaker integrates a wireless communication module, which can be linked with smart sockets and lighting control systems, and supports remote control via a mobile app.

Power distribution in commercial complexes: Smart power distribution accessories enable tiered energy consumption metering. A landmark building in Shanghai reduced its electricity costs in public areas by 22% through the Zheyuan system.

Rail transit and data centers:

Provided high-seismic-resistant circuit breakers for Beijing Subway Line 16, which withstood a simulated earthquake of magnitude 8;

The data center-specific circuit breaker supports automatic switching between dual power supplies, ensuring zero-interruption operation of the server cluster.

Smart grid transformation:

The circuit breaker has a built-in power quality analysis chip to assist the State Grid in monitoring harmonics and voltage fluctuations, thereby improving the reliability of power distribution.

In a power grid upgrade project in northeastern Brazil, Zheyuan products helped reduce line losses by 15%, benefiting 2 million residents.

Emergency power supply system:

Miniature circuit breakers are used in backup power supplies for hospitals and data centers to achieve millisecond-level fault switching and comply with the IEC 60947-2 international standard.

New energy vehicle charging facilities:

We have developed a liquid-cooled molded case circuit breaker that can withstand extreme temperatures of -40℃ to 85℃, meeting the high current requirements of fast charging stations. It has been supplied in batches to Tesla V4 Superchargers.

Naval Architecture and Ocean Engineering:

The explosion-proof circuit breaker is ATEX certified and used on offshore oil platforms, with a salt spray corrosion resistance of up to 1000 hours of neutral salt spray testing.
