Figure 17 SLIC VOLTAGE RATINGS AND TISPPBLx PROTECTION LEVELS
application circuit
Figure 18 shows a typical TISPPBLx SLIC card protection circuit. The incoming line conductors, R and T,
connect to the relay matrix via the series over-current protection. Fusible resistors, fuses and positive
temperature coefficient (PTC) resistors can be used for over-current protection. Resistors will reduce the
prospective current from the surge generator for both the TISPPBLx and the ring/test protector. The
