Application Notes
c Overcurrent Protection for Communication Facility
POSISTOR r Lead type: PTGL series
1. Applications
POSISTOR r is an efficient device to protect a telephone
line interface (SLIC: Subscriber-Loop-Interface-Circuit)
against AC line contact.
(1) Landline telephones or FAX machines
(2) Telephone interface of STB, VoIP equipment
(3) Any other equipment of communication facility having
a phone line interface
Replacement idea for a current fuse.

Tip
2. Benefits
(1) Automatic reset from protective trip up to 265V AC
line contact
(2) Compatible with the 600V over voltage test by
UL60950
(3) High resistance to the lighting surge (*A surge
absorber is still required to protect SLIC)
3. Recommended part numbers
Choose an appropriate part number based on the hold
current and on the resistance value required to the
operation current of SLIC.
