H908 Split-Core Current Switch, Adjustable Trip Point - Installation Guide

The H908 is a current-sensitive switching device that monitors the current (amperage) in the conductor passing through it. A change in amperage in the monitored conductor that crosses the switch (setpoint) threshold plus the hysteresis value causes the resistance of the FET status output to change state, similar to the action of a mechanical switch. In this model, the setpoint is adjustable through the action of a 20-turn potentiometer (see the Calibration section).
