GFEVG Dual-Circuit Battery Fuse Holder — 400A / 800A, 12V–500V DC
Two M8-stud circuits on one black Bakelite base. 400A per circuit, 800A in dual use, 2 kA breaking, built for car and ship battery protection.
12V–500V DC
Parafusos M8
2 kA Breaking
Bakelite V-0
Because dual-battery setups need two protected circuits on one mounting point, installers choose the GFEVG dual-circuit holder. In particular, it carries 400A per circuit and 800A in dual use. Moreover, both studs are M8. As a result, it suits dual-battery cars, yachts and RVs up to 500V DC.

Why dual-battery builds choose it
Because dual-battery setups run separate starter and house banks, they need two fuses on a shared mounting footprint. Consequently, installers use one GFEVG block instead of two single-circuit holders. For example, a yacht uses one stud for the starter battery and one for the house bank. However, never exceed 400A on either circuit. In addition, the M8 studs accept standard heavy cable lugs.
How to install
First, bolt the base near the battery busbar. Next, connect each battery lead to its own M8 stud. Then insert a correctly rated protection fuse into each circuit. Finally, torque the M8 nuts to specification and close the cover. If you need a specific stud length or lug size, simply specify at order time.
