| Datasheet | Download Datasheet |
The TimeMark C259 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 380-500 V AC. Adjustment: field adjustable. Trip delay: undervoltage 1-5 s (adjustable). Restart: 0.2-10 min (adjustable). Reset: automatic.
Output: 2C DPDT, 3 A at 480/600 V AC 80% PF; 10 A at 240 V AC 80% PF resistive. Mounting: surface mount. Indicator: FAILURE INDICATOR LED.
