| Datasheet | Download Datasheet |
The TimeMark 2501-240 is a 3-phase monitor for 240 V AC, 50/60 Hz systems. It drops its output relay out on phase loss, phase reversal, undervoltage and voltage unbalance and resets once the fault clears.
Trip points: undervoltage 168-229 V AC; unbalance 2-10% adjustable (NEMA definition). Adjustment: field adjustable. Trip delay: undervoltage 1-10 s (adjustable). Reset: automatic.
Output: 1C SPDT, 30 A at 28 V DC/300 V AC 50/60Hz; 5 A at 480/600 V AC 50/60Hz 0.75 PF. Mounting: surface mount. Indicator: NORMAL, LOW, REVERSE, UNBAL LEDs. Approvals: UL Listed to U.S. and Canadian safety standards.
