OptiStart T LTMR-250-M programmable engine control and protection system KEAZ 373800

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 has one Modbus RTU communication interface. The system implements the following protections: start time exceedance current overload during start rotor stall phase loss asymmetry high/low voltage protection zero point shift protection, etc. It features 9 discrete and 5 relay configurable outputs, as well as a communication interface and a built-in event log.
