The OLM Analog Three-Phase Load Monitoring Relay, developed by Borna Electronics, is designed to provide reliable overcurrent protection for both three-phase and single-phase loads. Offering high accuracy and long-term reliability, the OLM relay serves as an effective electronic alternative to conventional thermal overload (bimetal) relays.

The relay allows users to adjust both the maximum permissible current and trip delay time, enabling flexible protection for a wide range of industrial applications. Available in multiple current ranges from 1 A to 60 A, the OLM relay is suitable for protecting motors, pumps, compressors, and other electrical loads
