Bussmann NTN-R-60 Class H/R Neutral Dummy Fuse, 35-60A, Non-Indicating
The Bussmann NTN-R-60 is part of the Eaton Bussmann NTN series of dummy fuse neutrals, engineered to complete the neutral pole of a fusible switch or disconnect where Class H or Class R fuses are used in the line poles. Rated for the 35-60A range, this non-indicating neutral block maintains proper circuit continuity in the neutral position without providing overcurrent protection, since the neutral conductor in most systems is not intended to be fused. As the designated neutral component in the NTN series, it ensures the neutral leg of a multi-pole fusible switch is properly seated and electrically continuous, matching the physical footprint of the Class H and Class R fuses used in the other poles. Built to those same fuse dimensions, the NTN-R-60 fits standard fuse clips and holders sized for the 35-60A range, simplifying panel and switch assembly.
Key Features
- Amperage Range: Rated for the 35-60A class range, matching Class H and Class R fuse dimensions for direct fit in fuse clips sized for this range.
- Dummy Fuse Neutral Design: Functions as a solid neutral link rather than an overcurrent device, allowing the neutral pole of a fusible switch to be completed without installing an actual fuse.
- Class H, R Compatibility: Sized to the standard Class H and Class R fuse form factor, ensuring proper fit in switches and panels designed for these fuse classes.
- Non-Indicating: Does not include a blown-fuse indicator, consistent with its role as a neutral continuity device rather than a protective fuse.
- Purpose-Built Neutral Replacement: The NTN-R-60 is specifically designated for the neutral position in circuits protected by Class H or Class R fuses in the 35-60A range, ensuring the neutral pole is neither left open nor incorrectly fused.
- Eaton Bussmann NTN Series: Manufactured as part of the Eaton Bussmann NTN series of neutral fuse replacements, built for compatibility with Bussmann fuse holders and disconnect switches.

Why Bussmann?
Bussmann by Eaton is a recognized name in circuit protection, and the NTN series neutral dummy fuse carries that same attention to fit and function into the neutral pole of fusible equipment. Designed to match the dimensions of Class H and Class R fuses, the NTN-R-60 helps ensure a secure, code-appropriate fit in switches and panels rated for the 35-60A range, supporting reliable, code-compliant, professional-grade electrical installations for commercial and industrial systems.

Bussmann NTN-R-60 – Frequently Asked Questions
1) What is a Bussmann NTN-R-60 neutral dummy fuse actually for?
The NTN-R-60 is a solid neutral link shaped like a fuse. It drops into the neutral pole of a fusible switch or disconnect so that pole stays electrically continuous without being fused. It provides no overcurrent protection at all, which is the point: in most systems the neutral conductor is not meant to be fused, but the pole still has to be closed and seated. Use it where Class H or Class R fuses occupy the line poles.
2) Will the NTN-R-60 fit my 60 amp fusible disconnect's fuse clips?
It is built to the 35-60A Class H and Class R fuse dimensions, so it seats in fuse clips and holders sized for that range, which on a 60 amp switch is the same clip spacing your line-pole fuses use. If your switch is a 100A or 30A frame, the clip dimensions differ and you need the NTN sized to that range instead.
3) Can I just put a regular 60 amp fuse in the neutral pole instead of a neutral dummy fuse?
No. Fusing the neutral is the problem the NTN-R-60 exists to avoid: an open neutral on a multi-pole system is a hazard, and a fuse in that pole can open while the line poles stay energized. The NTN-R-60 keeps the neutral pole seated and continuous without introducing a protective element, so the neutral is neither left open nor incorrectly fused.
4) Does the NTN-R-60 work in a switch that takes Class R fuses, or only Class H?
Both. The NTN-R-60 is sized to the standard Class H and Class R form factor in the 35-60A range, so it suits switches and panels designed for either class. Class R holders include rejection features that Class H fuses will not enter, and the R designation in the part number is what makes this neutral suitable for those rejection clips.
5) What is the exact part number to order this Bussmann neutral for a 60A Class R switch?
Order Bussmann NTN-R-60. That is the Eaton Bussmann NTN series neutral dummy fuse covering the 35-60A Class H/R range, and the part number is the full manufacturer designation, no suffixes or options to specify.
6) I am rebuilding an old switchgear neutral pole where somebody installed a fuse. Is this the right replacement?
Yes, that is one of the intended uses. The NTN-R-60 replaces a neutral fuse position in existing switchgear or a panelboard neutral pole, provided the line poles use Class H or Class R fuses in the 35-60A range so the clip dimensions match. It restores continuity in that pole with no protective element in the neutral.
7) Is the NTN-R-60 an indicating fuse? Will it show if something has opened?
Non-indicating. There is no blown-fuse indicator, which is consistent with the part being a continuity link rather than a protective device. There is nothing in it to open, so troubleshooting a tripped circuit means looking at the line-pole fuses, not the neutral.
8) Do I need one NTN-R-60 per switch or one per pole?
One per neutral position. A multi-pole fusible switch carries fuses in the line poles and a single neutral pole, so one NTN-R-60 completes that pole. If you are standardizing across a facility, count the neutral positions in your 35-60A Class H/R switches, not the total poles.
