MD0630T41A-2 is a IR type leakage current sensor which supports the detection of DC current 2~15mA, AC current 3~100mA. The alarming value can be set into 4mA-20mA, 6mA, 10mA or other values in the range. Not only type B detection mode but also the push-pull output can be used for leakage protection. This small RCD have the advantages as follows: cable (horizontal) installation, compact size,digital output,IR communication, standard compliant etc.

Product Application
Leakage sensors, in photovoltaic applications, are the process of converting alternating current to a standard form of direct current or alternating current and then delivering it to where it is needed. Among them, only when the current of the conversion system at all levels is normal, can the safety of the current transportation process be guaranteed. It can accurately measure the current of the key links of the system, detect and report abnormal conditions such as leakage in time, and avoid safety accidents.
