PML630 Load-Shedding Controller Specification

This document specifies the requirements for the PML630 load-shedding controller, an integrated protection and load-shedding solution designed to prevent blackouts in industrial and utility power networks by selectively dropping non-critical loads. It details mechanical construction, multiple load-shedding functions (fast, slow, manual, underfrequency), network handling capabilities, failsafe mechanisms, and integration with IEC 61850-based systems.
