Note on Electrical Characteristics
Vocabulary
I
hold
= Hold current: maximum current device will pass without tripping in 23 still air.
I
trip
= Trip current: minimum current at which the device will trip in 23 still air.
V
max
= Maximum voltage device can withstand without damage at rated current (I
max
)
I
max
= Maximum fault current device can withstand without damage at rated voltage (V
max
)
P
d typ.
= Typical power dissipated from device when in the tripped state at 23 still air.
R
min
= Minimum resistance of device in initial (un-soldered) state.
R
1max
= Maximum resistance of device at 23 measured one hour after tripping or reflow soldering of 260 for 20 sec.
Value specified is determined by using the PWB with 0.030”*1.5oz copper traces.
Caution: Operation beyond the specified rating may result in damage and possible arcing and flame.
Specifications are subject to change without notice.
