Bussmann Eaton NBE Series Fast-Acting Current-Limiting Fuse, 1500V

The Bussmann Eaton NBE Series fast-acting, current-limiting fuse is engineered to deliver dependable overcurrent protection for demanding 1500V electrical systems. Built as a single-barrel fuse, the NBE Series is offered across a range of amp ratings from 35A through 80A (35A, 40A, 70A, and 80A), giving electrical professionals a consistent, code-compliant option for high-voltage current-limiting protection on a single product platform. Its fast-acting response is designed to interrupt overcurrent conditions quickly, while the current-limiting construction helps reduce let-through energy and protect downstream equipment, conductors, and connected loads from damage during a fault event. At approximately 1.12 lb, the NBE Series fuse is sized for use in compatible 1500V-rated fuse holders, disconnects, and combination controllers commonly found in solar, industrial, and commercial power distribution equipment.

Key Features

  • Voltage Rating: Rated 1500V, supporting high-voltage current-limiting fuse applications where standard low-voltage fuses are not suitable.
  • Amp Rating Range: Available across the NBE Series in 35A, 40A, 70A, and 80A ratings, allowing the correct amp rating to be matched to the specific circuit being protected.
  • Fast-Acting Design: Fast-acting operation provides a quick response to overcurrent conditions, helping minimize exposure time to fault current.
  • Current-Limiting Performance: Current-limiting construction helps reduce peak let-through current and energy during a fault, protecting downstream components and wiring.
  • Single-Barrel Construction: Single-barrel design supports straightforward installation into compatible 1500V fuse holders and disconnect switches.
  • Non-Indicating Body: Non-indicating fuse construction per manufacturer specification, without a built-in blown-fuse indicator.
  • Approximate Weight: Approximately 1.12 lb per fuse, consistent with the NBE Series single-barrel form factor.

Bussmann NBE-35 – Frequently Asked Questions

1) What amp ratings does the Bussmann NBE Series 1500V fuse come in?
Four ratings are offered across the NBE Series: 35A (NBE-35), 40A (NBE-40), 70A (NBE-70), and 80A (NBE-80). There is no 50A or 60A in the family, so if your circuit calculation lands between 40A and 70A you either move up to the 70A or select a different series. Match the rating to the circuit being protected before you order.
2) Can I use a Bussmann NBE fuse in a 1000V solar combiner box?
Electrically yes on voltage headroom, since the NBE is rated 1500V and a fuse may be applied at or below its voltage rating, but mechanically it only works if the holder accepts the NBE single-barrel body. The NBE is built for 1500V-rated holders, disconnects, and combination controllers. If your combiner uses 1000V PV fuse holders, the barrel and clip geometry will not match and you need a fuse built for that holder instead.
3) I need a replacement fuse for an existing 1500V NBE installation. Is this the same part?
Yes, provided you match the amp rating on the old barrel. The NBE Series is sold as the direct genuine Bussmann replacement for existing 1500V NBE installations, in 35A, 40A, 70A, and 80A. Read the printed rating off the fuse you are pulling and order the matching NBE-35, NBE-40, NBE-70, or NBE-80.
4) Does the NBE fuse have a blown-fuse indicator?
No. The NBE Series is a non-indicating fuse, with no built-in indicator pin or flag. On a 1500V string or feeder you will need to verify an open fuse with a meter, or rely on holder-mounted or monitored indication elsewhere in the assembly. If your maintenance procedure depends on visual blown-fuse identification, specify an indicating fuse type instead.
5) What does fast-acting and current-limiting mean for protecting my inverter or downstream gear?
Fast-acting means there is no intentional time delay, so the element clears quickly on an overcurrent and keeps fault exposure short. Current-limiting means the fuse cuts off the fault before the first full half cycle peaks, which holds down peak let-through current and energy reaching conductors and connected equipment. That combination suits semiconductor and DC power electronics work, but it also means a fast-acting fuse will not ride through motor inrush the way a time-delay fuse does, so size accordingly on motor loads.
6) Is the Bussmann NBE fuse UL Listed?
For listing and agency approval details on the NBE Series, Bussmann directs users to contact the factory. The published specification covers the 1500V rating, the fast-acting current-limiting element, and the non-indicating single-barrel body. If your submittal requires a specific agency listing reference, get that confirmation from Eaton for the exact amp rating you are specifying.
7) How heavy is a single NBE fuse, and does it ship individually?
Each NBE fuse weighs about 1.12 lb and comes in standard packaging, sold as individual fuses by amp rating rather than in a multi-pack. That weight is typical of the single-barrel high-voltage form factor and is worth noting if you are stocking a spares kit for several combiner boxes.
8) Where is the NBE Series fuse typically used?
It is applied where a 1500V current-limiting fuse is called for: solar and renewable power distribution, combiner boxes, panelboards and switchgear, and feeder or equipment branch circuit protection in commercial and industrial distribution. Standard low-voltage fuses are not suitable at these voltages, which is why the NBE carries a 1500V rating.
