In areas prone to thunderstorms or in power grids with unstable
power supply voltage, it is recommended to use under voltage
trip units with time delay functions, to prevent the circuit breaker
from tripping due to short-time voltage drop. The delay time can
be selected usually from 0.3s,0.5s,0.7s,1s, 3s, 5s, to 10s by users.
For special requirements on the delay time, please contact Eaton.
