- Protection of cable feeders and distribution transformers.
Material Composition & Structural Characteristics:
- Plug-in Design: Features a removable plug-in unit for quick, safe insertion and withdrawal during maintenance.
- Expandability: Supports an optional add-on card for RTD sensors or thermistor elements for direct bearing and winding temperature measurement.
Working Principle:
The REM610 utilizes high-speed digital signal processing to continuously monitor motor parameters. Its advanced thermal model calculates the exact thermal stress on the motor windings, allowing for precise tripping before insulation damage occurs.
Installation Requirements:
- Utilize the plug-in design for easy switchgear commissioning.
- Connect RTD sensors if direct temperature monitoring is required.
Usage Precautions:
- Note that the REM610 has been an inactive product since 2017.
- Ensure correct configuration of the thermal model constants to match the specific motor being protected.
