The TimeMark 2744-220 is a 3-phase motor jam monitor for 1-5 A AC per phase. It protects motors against jams: after the start delay, its relay drops out when the current in any line rises above the trip level.
Sensing: direct 1-5 A; external CT above 5 A (TimeMark 276). Control supply: 240 V AC. Line: 190-250 V AC. Trip point: 1-5 A (adjustable). Hysteresis: 4% max. Start delay: 5-15 s (adjustable start delay). Reset: automatic; manual with an external N.C. switch.
Output: 1C SPDT, 10 A at 240 V AC resistive. Mounting: surface mount, screw terminals. Indicator: READY and TRIPPED LEDs. It operates from -29 to +55 °C.
