IoT-based residual current circuit breaker

New Products / New Technology

The operating principle of this product relies primarily on electronic and electrical components. When an electrical device or circuit is subjected to water immersion, the built-in MCU‑based electronic circuitry instantly activates shielding and absorbs leakage current, diverting it through the PE (protective earth) conductor to ground, thereby achieving equipotential bonding and reducing the risk of electric shock to humans. Product features include: remote control, manual switching, over‑temperature protection, undervoltage/overvoltage protection, overload protection, phase‑loss detection, short‑circuit protection, water‑immersion‑induced electric‑shock prevention, residual current protection, earth‑wire monitoring, timed tripping, surge protection, front‑end power‑outage notification, and power‑factor analysis.

Electrical Fire-Prevention Current-Limiting Protector

New Products / New Technology

Product Features: Microsecond-level short-circuit current-limiting protection, overload alarm, over-temperature protection, leakage protection, over‑ and under‑voltage protection; RS485 interface with a dedicated gateway enables remote switch‑on/switch‑off control, remote parameter adjustment, remote reset, and more. Product Characteristics: The system can perform online analysis of electrical circuit faults and issue early warnings and alarms based on preset thresholds. It provides comprehensive system protection and allows flexible configuration of power‑off protection settings. Users can easily set warning and alarm thresholds via the web platform or mobile app, and by adjusting the circuit's current‑limiting threshold, they can fine‑tune protective settings after installation to reduce electrical safety risks.
