The MRMV4 is a motor protection relay that provides precise and reliable protective functions and 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 MRMV4 is available in 192 variants, that cover all combinations of properties that you might need or not need for your application. Each variant is uniquely specified by a typecode of form MRMV4-2xxxxx (i.e. 5 digits/letters following the '-2'). Check the Order Form (depicted below, or in the brochure DOK-FLY-MRMV4-2E or in the user manual MRMV4-3.6-EN-MAN) for a complete overview.
