Over Current Protection for Communication Facility
POSISTORr 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
(1) Automatic reset from protective trip up to 265V AC
(2) Compatible with the 600V over voltage test by
(3) High resistance to the lighting surge (*A surge
Choose an appropriate part number based on the non-
operating current and on the resistance value required to
the operation current of SLIC.
