First value is for standard 50 ms/
three-cycle interrupting time.
Second value is for optional 83 ms/
five-cycle interrupting time (stored-
energy operator only).
2
If controller power fails,
capacitors retain sufficient charge
to open circuit breaker within
300 seconds, with minimum open
command duration 100 ms.
3
Capacitors discharge to 10 V or
less within five minutes after
disconnecting plug.
4
Capacitor charging time
approximately 30-35 seconds
from complete discharge,
approximately 12 seconds after
OPEN-CLOSE-OPEN sequence.
5
On initial energization, power
demand is approximately 100 W,
declining to approximately 20 W
when capacitors are fully charged.
When the circuit breaker operates
(open or close), power demand
again increases to approximately
100 W, declining to approximately
20 W when capacitors are fully
charged.
6
For stored-energy operator, power
requirement for second trip coil is
approximately 70 W (dc) or 50 VA
(ac). Power requirement for
undervoltage device is
approximately 20 W (dc) or
20 VA (ac).
