Feature Description

Fault protection function: In the event of a product malfunction, a fault indicator will be activated, and the self-protection function will be initiated.

Overload Protection Function: Cuts off the overloaded circuit after continuous overload for 3 seconds to prevent fires caused by overload.

Short-circuit protection function: Cuts off the circuit power within 150 microseconds when a 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 cable temperature within the protected power distribution circuit in real time. If the cable temperature exceeds the set threshold, an alarm message is sent to the host computer, and the alarm status remains until reset.
