Notes:
1 Breaker must hold 100% of rated current
and must trip at 150% and above, within
the time limits shown in curve.
Trip times specified at 25° ambient with
no preloading.
2 To adjust the breaker rating for ambient
temperature multiply the breaker rating
by the factor. (ex: 5 amp rating at 0°C: 5
x .67 = 3.3 amp. Select 3 amp rating.)
2500 amps @ 32 VDC only. AIC rating is
1000 amps for AC applications.
