| Datasheet | Download Datasheet |
The TimeMark 2742-115 is a 3-phase over/under current monitor for 1-5 A AC per phase. It watches all three lines for overcurrent as shipped, and a jumper converts it to undercurrent; its relay stays energized while the current is in range and drops out on a fault.
Sensing: direct 1-5 A; external CT above 5 A (TimeMark 276). Control supply: 120 V AC. Line: 100-130 V AC. Trip point: 1-5 A (adjustable; over or under current per the jumper). Hysteresis: 4% max. Trip delay: 0.2-20 s (adjustable, ±5%). Reset: automatic; manual with an external N.C. switch.
Output: 2C DPDT, 10 A at 240 V AC resistive. Mounting: surface mount, screw terminals. Indicator: FAULT and TRIPPED LEDs. It operates from -29 to +55 °C.
