| Datasheet | Download Datasheet |
The TimeMark 2581-208 is a 3-phase monitor for 208 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 189 V AC ±2%, fixed (10% below nominal). Adjustment: fixed, factory set. Trip delay: phase loss / reversal 50 ms (set or reset).
Output: 1C SPDT, 10 A at 240 V AC resistive. Mounting: surface mount, 0.250" quick-connect terminals. Approvals: UL Recognized (U.S. and Canada).
