Bussmann NBC-150 Fast-Acting Fuse, 1500V, 150A, Non-Indicating, Blade Terminals

The Bussmann NBC-150 is an Eaton Bussmann series NBC fast-acting fuse engineered for reliable overcurrent protection in demanding electrical systems. Rated 1500V and 150A, this fuse features a non-indicating design and blade end x blade end terminal construction for straightforward installation into compatible fuse blocks and disconnect assemblies. The fast-acting fuse element responds quickly to fault conditions, helping protect connected equipment and conductors from damage caused by short circuits and sustained overcurrent events. The blade end x blade end terminal style is designed to seat directly into matching blade-type fuse holders and disconnect switches, simplifying installation and replacement for electricians working on high-voltage 1500V circuits where dependable, fast-clearing overcurrent protection is essential.

Key Features

  • Voltage Rating: 1500V rating supports use in high-voltage electrical circuits and equipment.
  • Amperage Rating: 150A rating provides dependable overcurrent protection for the connected load.
  • Fast-Acting Element: Fast-acting fuse design responds quickly to short-circuit and overload conditions, helping limit fault energy and downstream damage.
  • Non-Indicating Body: Non-indicating construction, without a blown-fuse indicator window, for a straightforward fuse body design.
  • Blade End Terminals: Blade end x blade end terminal configuration for compatibility with blade-style fuse blocks and holders, simplifying mounting and replacement.
  • Eaton Bussmann Series NBC: Part of the Eaton Bussmann series NBC fuse lineup, engineered for consistent, repeatable performance.

Bussmann NBC-150 – Frequently Asked Questions

1) Will the Bussmann NBC-150 fit a 1500V DC solar or battery string circuit rated 150 amps?
The NBC-150 is rated 1500 V and 150 A, so it matches a circuit whose system voltage does not exceed 1500 V and whose continuous load is protected at 150 A. It is a fast-acting element, so it clears short circuits and sustained overcurrents quickly rather than riding through inrush. If your load has a heavy motor or transformer inrush, a fast-acting fuse is the wrong choice and you want a time-delay type instead.
2) What kind of fuse holder does the NBC-150 need?
Blade end by blade end. The NBC-150 has a blade terminal at each end, so it seats into blade-style fuse blocks, holders, and disconnect switch assemblies sized for that terminal style. It will not drop into a ferrule or cylindrical clip holder, and it is not a bolt-through stud design.
3) Can I substitute an NBC-150 for a lower-voltage 150A fuse already in my disconnect?
Only if the terminal style and holder match. The NBC-150 uses blade ends at both ends and carries a 1500 V rating, so it can replace a 150 A blade-end fuse in the same blade-style holder at any system voltage up to 1500 V. A fuse's voltage rating must be equal to or greater than the circuit, never less, so do not go the other direction and drop a lower-voltage fuse into a 1500 V circuit. Also confirm the replacement is fast-acting if the original was, since swapping element speed changes how the circuit clears.
4) Does the NBC-150 have a blown-fuse indicator?
No. It is a non-indicating fuse, with no indicator window or pin to show the element has opened. If your maintenance routine depends on visual blown-fuse checks without pulling the fuse or metering the circuit, specify an indicating version instead.
5) Is the Bussmann NBC-150 a fast-acting or a time-delay fuse, and which should I use?
Fast-acting. The NBC series element is built to respond quickly to short-circuit and overload conditions, which limits fault energy reaching conductors and connected equipment. That makes it right for semiconductor, rectifier, and general high-voltage distribution protection where downstream devices cannot tolerate let-through energy. Circuits with motors, transformers, or capacitor charging draw a large starting surge and will nuisance-open a fast-acting fuse, so use a time-delay class there.
6) I need overcurrent protection in a 1500V panel build. What does the NBC-150 actually protect?
It protects the conductors and connected equipment on a 150 A branch in high-voltage distribution: panelboards, industrial and commercial power systems, and fuse block or disconnect switch assemblies. It is a single-pole device, so a multi-pole 1500 V circuit needs one fuse per ungrounded conductor, each in its own blade-style holder.
