Product Overview

As a core electrical safety device based on residual current protection technology, the residual current circuit breaker (RCCB) is designed to accurately monitor leakage faults in circuits and eliminate the risk of electric shock accidents at the root. In actual operation, it continuously monitors the current difference between the live and neutral wires in real time. Even if a weak leakage signal is detected, it can quickly cut off the power supply within milliseconds, firmly guarding the first line of defense for electrical safety. Crucially, the device has a high-sensitivity protection capability of 30mA. Whether it is direct electric shock from direct contact with a live object or indirect contact with the casing of a device that is charged due to leakage, it can effectively mitigate risks. It is widely applicable to residential, commercial, and industrial sites, building a stable and reliable electrical safety barrier for various scenarios.

Core Features

Accurate leakage detection: By comparing the vector relationship between phase and neutral currents in real time, it can stably identify residual currents ≥30mA, ensuring that leakage signals are not missed or misjudged, eliminating safety hazards from the detection stage.
Millisecond-level rapid power off: The built-in high-performance electromagnetic tripping mechanism can complete the power cut-off operation within 0.1 seconds once a dangerous leakage situation is detected, significantly shortening the electric shock time and minimizing electric shock injuries.
Convenient self-check protection: Equipped with a dedicated test button that can simulate real-world leakage scenarios, users can regularly verify whether the device protection function is intact without additional tools, ensuring that the device is always in effective working condition.
Clear fault indication: With the help of intuitive mechanical position marks, the normal operation status and tripping status of the equipment can be clearly distinguished. At the same time, the tripping cause can be accurately identified as routine operation or leakage action, which is convenient for subsequent fault investigation and processing
