Product Overview

MP3101S2 is a multi‑functional motor protection relay used for low‑voltage motor sets. It provides comprehensive motor‑fault protection, real‑time electrical‑parameter measurement and fault‑event logging. Modbus communication enables remote data reading and status uploading to SCADA or DCS systems. This legacy protection device is available as refurbished and new‑old‑stock spare parts for factory motor‑control‑center maintenance.

Application Notes

‑ Confirm current‑transformer ratio matches actual motor operating parameters. ‑ Auxiliary power source shall keep stable during whole operation cycle. ‑ Cut off power supply before parameter modification or hardware replacement. ‑ Typical deployment: industrial MCC cabinet, pump‑fan motor‑protection spare‑part stocking.
