Footnotes:
1
Circuit breaker is in closed position.
2
User must supply external time delay (typically using setting in reclosing relay) for the minimum reclose time interval of 0.3 s in accordance with
ANSI/IEEE.
3
Consult factory for -50 °C.
4
First value is for stored-energy operator; value after slash is for magnetic-actuator operator. For magnetic-actuator operator, add 10 ms if
command power is ac.
