PR 202 220Vac 380Vac Electronic Overload Relays 3-phase Motor Protection Relay
Inquire NowDescription
The PR 202 Electronic Overload Relay is a robust solution designed for the continuous monitoring of 3-phase power lines, providing essential motor protection against abnormal conditions. Compatible with motors of various sizes and types, this relay ensures optimal performance and safety. When abnormal values are detected, the PR 202 automatically triggers a release switch to shut down the circuit, preventing potential damage.
Equipped with an optional RS485 communication port, it enables seamless data upload of monitored parameters and alarm statuses to a remote control system, enhancing operational efficiency and safety.
