Power-up time
Time to power up < 11 s.
Power supply interruption
Per IEC 60255-11: 1979
The relay will withstand a 20 ms interruption
in the DC auxiliary supply, without
de-energizing.
Per IEC 61000-4-11: 1994
The relay will withstand a 20 ms interruption
in an AC auxiliary supply, without
de-energizing.
