Working Principle When a protective relay operates to clear a fault, it energizes the target module coil. The electromagnetic force moves a mechanical flag or indicator to the “operated” position, where it remains latched until manually reset. This provides a persistent visual record of the protective operation, allowing maintenance personnel to identify which protection element operated even if the fault has been cleared and the system restored to normal operation. The manual reset requirement ensures that operators physically acknowledge and investigate the cause of the operation.
Installation Requirements
