Bussmann NBB-C Series Current-Limiting Fast-Acting Fuse, 1500V

The Bussmann NBB-C Series Current-Limiting Fast-Acting Fuse from Eaton Bussmann is a single-barrel (1 barrel), C version fuse built for fast-acting, current-limiting overcurrent protection in demanding electrical systems. Rated at 1500V, this series is available in amp ratings from 35A to 70A, letting installers match protection levels to specific circuit requirements. The current-limiting, fast-acting design helps reduce let-through energy during a fault, supporting safer, code-compliant electrical distribution for industrial and commercial systems. As part of the broader Eaton Bussmann fuse lineup, the NBB-C series is intended for electricians, panel builders, and maintenance teams who need a dependable overcurrent protection device for high-voltage circuits.

Key Features

  • Amp Rating Range: The NBB-C series is offered in 35A, 50A, and 70A ratings, giving flexibility to match circuit protection needs across different load requirements.
  • Voltage Rating: Rated 1500V for high-voltage current-limiting fuse applications.
  • Current-Limiting, Fast-Acting Design: Fast-acting operation combined with current-limiting performance helps reduce fault energy let-through and protect downstream equipment and conductors.
  • Single Barrel Construction: 1 barrel, C version body configuration for this series.
  • Non-Indicating Body: Fuse Indicator is Non Indicating, without a blown-fuse visual indicator, for a simple, standard fuse body.
  • Standard Packaging: Packaging Type is Standard for straightforward stocking, ordering, and handling.

Bussmann NBB-C-35 – Frequently Asked Questions

1) What amp ratings does the Bussmann NBB-C fuse come in?
Three ratings: 35A, 50A, and 70A, ordered as NBB-C-35, NBB-C-50, and NBB-C-70. All three share the same 1500V rating, so the amp rating is the only selection you make. Match it to the circuit's protected conductor and load, not to the next size up.
2) What is the difference between a fast-acting current-limiting fuse and a time-delay fuse for motor circuits?
The NBB-C is fast-acting and current-limiting: it clears quickly and cuts the peak let-through energy during a fault, which is what you want protecting semiconductors, conductors, and switchgear downstream. A time-delay fuse instead rides through the inrush of a motor start or transformer energization. If you are fusing a motor where locked-rotor inrush would nuisance-open a fast-acting element, use a time-delay class fuse for that branch and reserve the NBB-C for the feeder or equipment protection role.
3) Can I use an NBB-C fuse on a 1000V DC solar or battery circuit?
The NBB-C is rated 1500V, so its voltage rating covers a circuit operating at or below that figure. Voltage rating is a ceiling, not a target, so a 1500V fuse is acceptable on a lower-voltage system provided the interrupting and application requirements of your equipment are met. For confirmation of applicable compliances on the NBB-C, Bussmann directs users to contact the factory.
4) Does the NBB-C fuse have a blown-fuse indicator?
No. The NBB-C is a non-indicating fuse, so there is no visual pop-up or flag to show it has opened. Maintenance crews will need to test continuity or check voltage across the holder to confirm a blown element. If your panel relies on walk-by visual inspection, specify an indicating fuse or add a downstream monitoring relay instead.
5) Is the NBB-C a single-barrel fuse body?
Yes, the NBB-C is built as a single barrel in the C body version. That matters when you are ordering a replacement into an existing holder, because the barrel count and body version determine the mounting footprint. A multi-barrel NBB variant will not drop into a holder set up for the single-barrel C body.
6) Does Bussmann publish UL or IEC compliance data for the NBB-C series?
The compliance record for the NBB-C reads "Contact factory." If your submittal package or facility spec requires a specific listing to be documented, get that confirmation from Eaton Bussmann for the exact amp rating you are buying before it goes on the drawing.
7) Where are Bussmann NBB-C 1500V fuses typically applied?
Industrial and commercial power distribution, transformer and motor circuit protection, panelboard and switchgear protection, and high-voltage current-limiting duty. The buyers are usually electrical contractors, panel builders, and plant maintenance teams replacing a like-for-like element in existing gear or building new assemblies at 1500V.
8) How is the NBB-C fuse packaged for stocking?
Standard packaging, which is the plain individual carton rather than a bulk or special pack. Ordering a mix of 35A, 50A, and 70A for a spares crib is straightforward on that basis; each amp rating is a separate part number.
