Over LED illuminates Single setpoint AC current monitor 120 or 240VAC AC currents from 50 to 400Hz

The Model 173 AC Current Monitor is a single setpoint AC current monitor. It can be used to detect either over current or under current, depending on whether the set point is set above or below the input current. The OVER L E D illuminates and the relay energizes when the current exceeds the set point. The UNDER L E D is lit and the relay is de-energized when the current is less than the set point.

Two versions, either of which can be connected to 120 or 240VAC, are available. One for current ranges up to 5 amps, the other for applications from 5 to 25 amps. For currents above 25 amps, matching CT’s are available. The Model 173 is not frequency sensitive and can be used on AC currents from 50 to 400Hz. The compact housing can be surface or DIN rail mounted with 1/4" quick connect terminals provided for input and output connections.
