H909HV-S6 Current Monitoring Switch Manual

This document provides specifications, installation instructions, calibration procedures, and troubleshooting for the Schneider Electric H909HV-S6 current-sensitive switching device, which monitors amperage in a conductor and changes its FET status output state when the adjustable setpoint threshold is crossed. It covers applications for under-current and over-current monitoring, low/high current handling via conductor wrapping or external CTs, and includes safety warnings, dimensional drawings, and agency approvals.
