Applications

This fuse protects main battery cables on 12V, 24V and 48V inverter installations, and works as DC bus protection in off-grid solar systems. The bolt-down blade design gives a low-resistance connection that tolerates vibration, which matters in marine and motorhome wiring where fittings are subject to movement. It also serves as replacement fusing in any installation already using MEGA fuseholders, and as spare stock for engineers working across multiple sites.

Installation notes

Fit this fuse only in a MEGA fuseholder rated for its current and voltage. Cable terminations and fuseholder connections should be torqued to the manufacturer's specification to avoid resistance heating. At 300A, DC fault energy is significant, so wiring and fuseholders should be specified and installed by a qualified electrician. Always isolate the battery before replacing a fuse.
