impulses.
Relay contacts 3a and 3b connect the line conductors to the SLIC via the TISPPBLx protector. Closing
contacts 3a and 3b connects the TISPPBLx protector in parallel with the ring/test protector. As the ring/test
protector requires much higher voltages than the TISPPBLx to operate, it will only operate when the contacts
3a and 3b are open. Both protectors will divert the same levels of peak surge current and their required
current ratings should be similar. The TISPPBLx protector gate reference voltage comes from the SLIC
negative supply feed (V
