250A SERIES
that protects 190-480VAC, 50/60Hz motors regardless of size
from low and high voltage, unbalance/single-phase, and reversephase.
The product provides a user selectable nominal voltage
setpoint and the voltage monitor automatically selects between
the 200V and 400V range. The 250A also features adjustable or
manual restart delay.
This unique microcontroller-based voltage and phase-sensing
device constantly monitors the 3-phase voltages to detect
harmful power line conditions. When a harmful condition is
detected, the output relay is deactivated after a specified trip
delay. The output relay reactivates after power line conditions
return to acceptable levels. The Model 250A includes advanced
single LED diagnostics. Five different light patterns distinguish
between faults and normal conditions.
