Description
The PR201 3-Phase AC Motor Protection Relay is an advanced solution engineered to monitor three-phase power lines continuously for any irregularities. This versatile relay is compatible with motors of all sizes and types. When the PR201 detects any abnormal conditions, it promptly activates the release switch to shut down the motor, ensuring safety and efficiency. Additionally, the relay features an RS485 communication port, enabling remote monitoring of data and alarm statuses.
