TISP4xxxJ1BJ Overvoltage Protector Series

APPLICATIONS INFORMATION

Y Configuration Design

This protection configuration has three modes of protection. The RING to TIP terminal pair protection is given by the series combination of

Similarly for the other terminal pairs, RING to GROUND protection is given by the series combination of Th1b and Th2 and the terminal pair

protector, carries the sum of the Th1a and Th1b currents, see Figure 13. The current rating of Th2 must be twice that of Th1a and Th1b.

GR-1089-CORE Designs

The main impulse waveforms of the standard are 500 A, 2/10 and 100 A, 10/1000. Assuming fuse current limiters, F1a and F1b, a suitable

Th1a and Th1b protector for these conductor currents is the TISP4xxxH3BJ series of devices. The ground return protector, Th2, must be rated

for at least 1000 A,2/10 and 200 A, 10/1000. A suitable Th2 protector for these ground currents is the TISP4xxxJ1BJ series of devices. This

arrangement is shown in Figure 14 and the following table lists all the catalogue device combinations.
