I. Overview
Single-phase electrical fireproof current-limiting protector is primarily used for protecting against short-circuit and overload faults in the terminal lighting circuits of places with significant fire hazards. It can reliably eliminate the arc and spark ejection from short-circuit or overload fault points, thus preventing short-circuit fires at their source. Particularly suitable for: various professional markets, large shopping malls, cultural heritage units, religious sites, etc.

III. Features and Specifications
Fault Protection Function: When the product malfunctions, it will emit a fault indicator and activate the self-protection feature.
Overload Protection Function: Cuts off the overload circuit after continuous overload for 3 seconds to prevent fires due to overload.
Short-circuit protection function: Cuts off the circuit power when the protected distribution circuit experiences a short circuit, preventing fires caused by the short circuit.
Real-time Current Measurement Function: Measures the current magnitude in the protected distribution circuit in real time.
Communication Function: Supports connection to electrical fire monitoring equipment for remote monitoring.
Real-time temperature measurement feature: Monitors the temperature of the cables in the protected power distribution circuit in real-time. When the cable temperature exceeds the set threshold, an alarm message is sent to the host, and the alarm status remains until reset.
Operation record feature, which allows external operations on the protector to be transmitted and saved on the host computer via communication.
