Semiconductor fuses
Semiconductor (AC) fuses

®
Protistor Square-body Fuses
PSC gGR sizes 000/00
gGR - 690 VAC DIN 00/000 (full range)

•EN 60269-2-1 compliant

•Compliance with gG gate values on melting and not melting

•Low dissipated power

•No derating for variable current

•Good withstand to repeated overloading

•Withstand to exceptional overloads
(same as Protistor fuses)

•Cable protection

Functionalities

Two functions:
- to protect cables from overloads,
- to protect semi-conductors from short-circuits.
