PV-100ANH1
Bussmann PV-100ANH1 NH-style photovoltaic fuse, 100 A at 1000 Vdc, NH1 blade, gPV and UL 2579 for combiners.
The PV-100ANH1 is a Bussmann NH-style photovoltaic fuse rated 1000 Vdc at 100 A in the NH1 blade body. It is designed for the combiner and inverter protection of a solar installation, where a large DC current must be interrupted without a natural zero crossing, so it carries the gPV class and meets UL 2579 and IEC 60269-6. The NH series runs from 32 A to 400 A across NH1, NH2 and NH3 sizes, and the blade version drops into a standard NH fuse block for quick tool-less replacement, while a bolt-on version with a common hole pattern integrates into a standardised busbar for a lower-inductance, fewer-parts build. The high current density of the NH construction means a compact fuse can carry a large string current at high ambient, which is what a utility-scale combiner needs. Match the fuse to a Bussmann blade block such as the SD-D or SB-D series, and size it above the combined array current at the hot ambient and below the cable rating. Every fuse BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Availability of larger NH ratings is confirmed per project, and BeiLuo reserves supply against your forecast.
FAE Professional Review
The PV-100ANH1 is the NH1 combiner fuse for higher-current solar arrays, and the standard bolt-hole pattern is the feature that matters: it lets a combiner use one busbar design across the whole 32 to 400 A range. Pair it with the matching SD or SB block and size it with the ambient derating.

Frequently Asked Questions
What is the PV-100ANH1 rated for?
It is rated 1000 Vdc at 100 A in the NH1 blade body, to the gPV class and UL 2579, with a 50 kA breaking capacity. The NH series covers 32 A to 400 A.
Size it above the combined array current at the hot ambient.
Blade or bolt-on version?
Choose the blade version for a fuse block and quick tool-less replacement, and the bolt-on version when the fuse integrates into a standardised busbar for a lower-inductance, fewer-parts build. The bolt-hole pattern is common across the current range.
Pick the mounting that fits the combiner.
Is lead time longer for this fuse?
Larger NH ratings are scheduled per project through Bussmann authorized channels. BeiLuo reserves supply against your forecast and confirms lead time before an order.
