Compatibility And NH1 Holder Fit
This electric fuse only fits NH1 holders and NH1 fuse bases, so match the holder first. NH00, NH2 and NH3 holders take different sizes and will not accept it. Check the size listed on our fuse holder product page before you order.
The rated voltage is 500V AC, and the product page lists no DC rating. Without a suitable DC rating, the fuse may not clear a battery fault safely. Ask us to confirm the DC rating before you fit it to a battery bank.
Once confirmed, it can act as an inverter fuse on 250A supply cables. Choose cables rated for 250A from our battery cable range. Smaller systems may suit our 160A battery protection fuse instead.
Large battery banks often use our 5 hole battery busbar box to join cables. Browse more parts in our battery and inverter accessories range. Find more protection gear in our Switchgear & Protection range.
Best Use Cases For Battery Banks
- Installers replacing a blown HRC fuse after a fault.
- Factories and businesses running high-current inverter systems.
- Farms and off-grid properties with large battery banks.
Warranty Compliance And Trust
Read the general rules for fuse links in the IEC 60269-1 low-voltage fuse standard. CE, UKCA and EAC markings appear on the fuse, but they are not South African approvals.
Fitting must follow SANS 10142-1, the South African wiring code for low-voltage installations. A registered electrical contractor must fit it and issue a Certificate of Compliance under the Electrical Installation Regulations.
