Footnotes:
1.
First value is full-wave impulse withstand circuit breaker open or closed. Second value is chopped-wave impulse withstand, applicable only with circuit breaker closed.
2.
Standard 50 ms (3-cycle) with 48 Vdc, 125 Vdc or 250 Vdc trip voltage or capacitor trip with 83 ms (5-cycle) interrupting time optional.
3.
TRV values are in accord with IEEE C37.06-2009. TRV peak value u
c
is roughly equal to historic E
2
value in ANSI C37.06-2000. Value t
3
, time to voltage u
c
, is
approximately 1/1.138 times the T
2
value in ANSI C37.06-2000.
4.
First value is for standard 50 ms/3-cycle interrupting time. Second value is for optional 83 ms/5-cycle interrupting time (see note 1).
5.
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).
