➀
Manually or electrically operated. For
approximate impact weight, add 50% of
breaker weight.
➁
Contact Cutler-Hammer.
➂
For lower than maximum load currents, watt
loss may be estimated by reducing the full
load loss by the following:
W
L
= (I
L
/I
FL
)
2
W
FL
Where:
W
L
= Load Watts
W
FL
= Full Load Watts
I
L
= Actual Load Current
I
FL
= Full Load Current
