Dll-701 Small Single-phase Current Limiting Protector

Function

Short-circuit protection function

The protector monitors the current of the power line in real time. When a short-circuit fault occurs in the line, it can achieve rapid current limiting protection within 50 microseconds and send out an audible and visual alarm signal.

Overload protection function

When the current of the protected line is overloaded and the overload duration exceeds the action time (0~60 seconds can be set), the protector starts the current limiting protection and sends out an audible and visual alarm signal.

Over-temperature protection function in the meter

When the operating temperature of the internal device of the protector is too high, the protector implements over-temperature protection and sends out an audible and visual alarm signal.

Over-voltage and under-voltage protection function

When the protector detects that the line voltage is undervoltage or overvoltage, the protector sends out an audible and visual alarm signal.

Distribution cable temperature monitoring function

When the temperature of the monitored cable exceeds the alarm setting value, the protector sends out an audible and visual alarm signal.

Leakage current monitoring function

When the leakage of the monitored line exceeds the alarm setting value, the protector sends out an audible and visual alarm signal.

Communication function

The protector has an RS485 communication interface, which can send data to the background monitoring system to achieve remote monitoring.
