Bussmann 100NHG000BI NH000 gL/gG Knife-Blade Fuse-Link, 100A 500V AC

The Bussmann 100NHG000BI is an NH000 gL/gG fuse-link engineered to IEC 60269 standards for low-voltage overcurrent protection in industrial electrical systems. Rated 100A at 500V AC, this Class C gL/gG fuse-link delivers a 120 kA breaking capacity for reliable protection of cables and equipment in commercial and industrial power distribution. Its compact NH000 knife-blade design measures 79 mm long, 51 mm high, and 21 mm wide, fitting standard NH-style fuse holders and disconnect switches, while a combination fuse status indicator and insulated gripping lugs (IMGL) support safer, faster maintenance.

Key Features

  • Compact NH000 Size: Measures 79 mm long, 51 mm high, and 21 mm wide for standard NH-style fuse holder and disconnect switch compatibility.
  • Knife-Blade Contacts: Knife-blade fuse shape ensures a secure, low-resistance connection in NH-style fuse bases.
  • gL/gG Utilization Category: Class C gL/gG rating provides general-purpose protection for both cable and equipment circuits.
  • 100A / 500V AC Rating: Rated 100A at AC 500V for dependable overcurrent interruption in low-voltage industrial circuits.

Bussmann 100NHG000BI – Frequently Asked Questions

1) Will the Bussmann 100NHG000BI fit a standard NH000 fuse base or disconnect switch?
Yes. The 100NHG000BI is built to NH000 (size 000) knife-blade construction, so it drops into any standard NH000 fuse base, fuse switch disconnector or NH fuse holder. Body dimensions are 79 mm length, 51 mm height and 21 mm width. If your holder is sized NH00, NH1 or larger, this link will not seat correctly, you need a link in that size.
2) Is a gL/gG fuse-link the right type for protecting feeder cable and equipment, or do I need an aM type?
gL/gG is the general purpose utilization category, covering both cable protection and equipment protection on the same link, which is what the 100NHG000BI carries. It will clear both overload and short circuit conditions across the full range. aM links are partial range motor rated and only protect against short circuits, so they must be paired with a separate overload relay. For a feeder, a distribution panel or a mixed load circuit, gL/gG is the one to specify.
3) Can I use this 100A Bussmann NH000 fuse on a 400V or 480V industrial system?
Yes. It is rated 500V AC, so it covers 400V and 480V three phase distribution as well as 230/240V circuits. The rating is AC only, do not apply it to a DC bus. Current rating is 100A.
4) What fault current can this NH000 fuse-link safely interrupt?
Breaking capacity is 120 kA, with a 120 kAIC interrupt rating and 120 kA rated switching capacity. That covers the prospective short circuit current at most industrial service and sub-distribution points, so it can be applied downstream of large transformers without a separate current limiting device ahead of it. Compare the figure against the calculated prospective fault current at your board.
5) How do I tell if this fuse has blown without pulling it out of the holder?
It has a combination fuse status indicator built in, so a blown element shows visually at the face of the link while it is still seated. For a maintenance tech walking a switchboard that means you can identify the failed phase without de-energizing and extracting every link.
6) Do I need a fuse puller handle to change this Bussmann NH000 link?
The 100NHG000BI is supplied with insulated metal gripping lugs (IMGL), the insulated tabs on the face of the link that let you grip and extract it. Standard NH fuse pulling handles engage those lugs. Plain NH links without lugs require the jaw style puller instead.
7) Does this Bussmann fuse-link meet IEC and CE requirements for a European or export panel build?
It is manufactured to IEC 60269, the low voltage fuse standard, and is CE marked. That is the pairing a panel builder needs for an IEC specified board or an export machine going into a CE market. It is an IEC style link, not a UL Class J, RK5 or CC fuse, so it is not a substitute in a NEC panel built to UL 248.
8) Where is this NH000 100A fuse-link typically applied?
Industrial and commercial low voltage power distribution: switchgear and fuse switch disconnectors, panel feeders, cable and feeder protection, and equipment circuits. The gL/gG category means one link covers both the cable and the connected equipment, so it is a common standardization choice across a plant's sub-distribution boards.
9) What does the Bussmann 100NHG000BI weigh for a shipping or panel load count?
Each link weighs about 130.7 g. On a three phase board that is roughly 392 g for a full set of three.
