Motor control and protection system OptiStart T LTMR-250-P-T programmable KEAZ 373835

OptiStart T MRD motor control and protection relay - a protection and control system for a three-phase asynchronous motor with a rated current of 250A, voltage up to 690 V AC at 50 Hz. The MRD module is a programmable module. It features a Profibus DP communication interface. The system implements the following protections: start time limit exceeded starting current overload rotor stall phase failure asymmetry overvoltage/undervoltage protection zero point shift protection and others. It features 9 discrete and 5 relay configurable outputs, as well as a communication interface and a built-in event log.
