The TimeMark 173-25 is a current monitor for 5-25 A AC. Its relay energizes when the current rises above the set point and drops out below it, so it serves as an over- or an undercurrent relay depending on which contacts carry the load.
Sensing: built-in CT window (pass the conductor through the unit). Control supply: 120 or 240 V AC. Trip point: 5-25 A AC (screwdriver adjustable). Hysteresis: 2%. Accuracy: 1% max. Trip delay: 100 ms typical. Reset: automatic.
Output: 1C SPDT, 10 A at 240 V AC resistive. Mounting: DIN rail or surface mount, 0.250" quick-connect terminals. It operates from -29 to +60 °C.
