| Datasheet | Download Datasheet |
The TimeMark C2644R is a 3-phase monitor for 480 V AC, 60 Hz systems. It drops its output relay out on phase loss, phase reversal and undervoltage and resets once the fault clears.
Trip points: undervoltage 380-480 V AC. Adjustment: field adjustable. Trip delay: undervoltage 0.2-20 s (adjustable). Restart: approx. 3.5 min. Reset: automatic.
Output: 2C DPDT, 10 A at 240 V AC resistive. Mounting: surface mount. Indicator: TRIPPED (TRIP) and NORMAL (NORM) indicators. Approvals: UL Recognized and CSA Certified. It operates from -7 to +55 °C.
