The TimeMark 158BR is a 3-phase monitor for 208/240 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 160-260 V AC. Adjustment: field adjustable. Trip delay: phase loss / reversal 0.5 s. Restart: 5 min (short-cycle protection). Reset: automatic.
Output: 1C SPDT, 10 A at 240 V AC resistive. Mounting: DIN rail or surface mount. Indicator: TRIPPED LED (red); RESTART LED (green) on R versions. It operates from -29 to +55 °C.
