Overview
The 369 Motor Management Relay is an advanced digital relay designed to protect and monitor three-phase motors and their related mechanical systems. One of its standout features is the ability to "learn" specific motor parameters and adapt to individual applications. By analyzing values like motor inrush current, cooling rates, and acceleration time, the 369 Relay enhances its protective functions, offering tailored and efficient motor protection.Specifications
