Application

The MRMV4 is a protection relay which uses the latest Dual-Core-Processor Technology to provide precise and reliable protective functions. Also it is very easy to operate.

The MRMV4 provides all necessary functions to protect low and medium voltage motors at all power levels.

The protection functions are based on current and voltage measurement and supervise all thermal conditions, motor start sequence, stall and locked rotor, undercurrent and incomplete sequence.

Overcurrent functions and earth fault functions are also available as power protection, frequency and voltage elements.

The motor operation can be monitored by statistic and trend recorders.

The protection functions of the MRMV4 have been adapted to comply with the requirements of the VDE-AR-N-4110:2018.
