The MRMV4 is designed for motor protection applications and has a large package of monitoring and protection functions, such as motor star-up, thermal overload, incomplete start-up sequence. Voltage, power and frequency are supervised as well. The motor temperature can be monitored via an external sensor box (URTD).
