The monitoring relay Ex9JP-G is mainly used in photovoltaic installations for monitoring and protection to circuits connected to the power grid. This relay can provide protection against overvoltage, undervoltage, unbalanced phases, phase sequence and phase failure by analyzing voltage on each phase. It offers various combinations of protective functionalities with adjustable values for country specific standards or open setup.
