INTERRUPTION CHARACTERISTICS
PR02 Time to interruption as a function of overload power
for range: 5 R  R
n
 68 R
This graph is based on measured data under constant voltage
conditions; the data may deviate according to the applications.
PR02 Time to interruption as a function of overload power
for range: 68 R  R
n
 560 R
This graph is based on measured data under constant voltage
conditions; the data may deviate according to the applications.
PR03 Time to interruption as a function of overload power
for range: 0.68 R  R
n
 560 R
This graph is based on measured data under constant voltage
conditions; the data may deviate according to the applications.
APPLICATION INFORMATION
