Three-phase fire-resistant current limiting protector (wall-mounted) 250-360A

Three-phase current-limiting protector, effectively overcoming the issues of traditional circuit breakers and monitoring equipment, such as large short-circuit current, long time to interrupt short-circuit current, large arc sparks during short-circuit, and rapid restriction of short-circuit current at microsecond speed during lifespan short-circuit failures, providing line protection for the terminal branches and main lines in various electrical usage sites such as shopping malls, hotels, warehouses, residential areas, electric vehicle charging stations, and markets.

Feature Description

Fault Protection Function: When the product malfunctions, it will emit a fault indicator and activate self-protection features.

Overload Protection Function: Cuts off the overloaded circuit after 3 consecutive seconds of overload to prevent fires caused by overloading.

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 magnitude of current 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. When the cable temperature exceeds the set threshold, an alarm message is sent to the host computer, and the alarm status remains until reset.
