469-P5-LO-A20-E is a motor protection relay designed specifically for large and medium-sized motors, produced by the Multilin brand of General Electric (GE). It is equipped with an enhanced panel, providing a comprehensive and efficient protection mechanism for the motor.
This relay has multiple protection functions to ensure the stable operation of the motor. Firstly, it has an over torque protection function, which can monitor when the torque exceeds the threshold set by the user and timely protect the driving load from damage. In addition, the 469-P5-LO-A20-E also has RTD protection function, and its highly programmable RTD input can remind users to pay attention to dangerous environmental temperature changes. When the value reaches the threshold set by the user, it can trigger alarm, trip, or high-level alarm functions.
In addition to the above protection functions, this relay also has a ground fault protection function. This function protects the equipment by removing the DC component from hazardous currents, thereby avoiding the impact of phase to ground faults on the motor. In addition, relays also provide a large number of customizable settings, such as assigning inputs, adjusting time intervals, viewing or clearing data, etc., to increase their configurability.
In terms of design and construction, the 469-P5-LO-A20-E relay is protected by a DEMO metal suitcase and has characteristics of corrosion resistance, dust resistance, and high temperature resistance, which enable it to operate stably in various harsh industrial environments. Its packaging size and weight have also been carefully designed to facilitate transportation and installation.
Overall, the 469-P5-LO-A20-E is a comprehensive and stable motor protection relay. It provides a powerful protection mechanism for large and medium-sized motors, ensuring stable operation of the motor, reducing system downtime, and thus extending the service life of the motor. At the same time, its easy to configure and use characteristics make it an ideal choice in the field of motor management and protection.
