Product Description

The residual current monitoring relay is composed of a residual current transformer and a temperature sensor body. When the residual current detected by the residual current transformer in the protection line or the temperature sensor detects that the temperature exceeds the alarm setting value of the multi-function meter, the one-channel residual current relay will analyze, After confirmation, an audible and visual alarm signal and a control signal are issued.

Features

* Residual current alarm setting range is 300 ~ 1000mA, the adjustment step is 1mA
* With residual current protection function
* Temperature alarm setting range is 50.0-100.0°C, the adjustment step is 0.1°C
* Temperature protection function
* 2 relay outputs, various protection modes can be set
* Optional 2-way passive binary input
* Support sound and light alarm functions,
* Automatically jump to the alarm interface when protection occurs,
* Support manual silence and reset
* Cyclic recording of 100 events, not lost when power is off, stored for more than ten years
* Standard RS485 communication interface,
* MODBUS-RTU communication protocol
* Support manual self-test function
