Product Description

Functions & Applications
Real-time Monitoring The electrical fire current-limiting protector monitors short-circuit current, fault arc (optional), voltage, current, frequency, temperature, residual current, and remote communication status in real-time, displaying them clearly for full circuit visibility.
Alarm & Protection Function When detecting a short circuit, fault arc, or abnormal power consumption, the device triggers audible and visual alarms. It performs current-limiting protection within microseconds to prevent fire hazards instantly.
Fault Indication Function Equipped with self-diagnostic capabilities, it alerts users to internal malfunctions such as sensor probe failures, ensuring the monitoring system itself remains operational and reliable.
Communication Function Features RS485 or 4G communication modules. It transmits power data to smart safety cloud systems, enabling a remote supervision network for comprehensive electrical safety management.
