Surge arrester type 2
GAVE ELECTRO
developed to meet overvoltage
protection needs transmitted on
low voltage networks. These
overvoltages are mainly generated
by atmospheric lightening
although also might occur due to
industrial changeovers and
network failures.
Surge dischargers provide
common/differential protection.
The electrical schemes on PST
protectors combines high energy
MOV varistor with an specific gas
discharge tube GDT thus obtaining
high performance protection
characteristics.
Surge protectors PST are built with
plug-in modules with failure
indicator and a monobloc fix DIN
rail base which allows an easy and
fast replacement on maintenance
operations.
