The Eaton Bussmann 170M series contains many high-speed square-body fuse-link families. Catalog numbers are grouped around different construction sizes, current ranges, terminal arrangements, indicator options and voltage classes. A cross-reference can help an engineer or buyer find a candidate model, but a numeric sequence alone cannot establish electrical equivalence.
This guide lists selected catalog-number groups from the wider 170M family. It is intended to support product searches and RFQs. It does not assign one common rating to an entire range, and it must not be used as a blanket replacement chart.
1. Selected size 1 and related catalog groups
The wider catalogue includes the following size 1 or related family groups:
- 170M3008–170M3023
- 170M3058–170M3073
- 170M3108–170M3123
- 170M3158–170M3173
- 170M3208–170M3223
- 170M3258–170M3273
- 170M3308–170M3321
- 170M3358–170M3371

These ranges are useful as search starting points only. Check the exact model’s voltage, current, utilization category, fuse size, connection style and indicator configuration.
2. Selected size 2 and related catalog groups
Catalog-number families associated with size 2 or related square-body constructions include:
- 170M5138–170M5148
- 170M5188–170M5198
- 170M5238–170M5248
- 170M5388–170M5395
- 170M5408–170M5418
- 170M5438–170M5446
- 170M5458–170M5468
- 170M5494–170M5498
- 170M5508–170M5518
- 170M5531–170M5551
- 170M5558–170M5568
- 170M5588–170M5595
- 170M5644–170M5650
- 170M5688–170M5696
- 170M5738–170M5746
- 170M5922–170M5931
- 170M5952–170M5961
- 170M5966–170M5975
- 170M5981–170M5990
The ranges may contain models with different terminal constructions and ratings. Some use DIN blade-end interfaces; others use bolted tags or alternative square-body constructions. The exact product drawing is required to confirm fit.
3. Selected size 3 and higher-current catalog groups
The broader 170M family also includes larger fuse constructions and higher-current groups, including examples such as:
- 170M6008–170M6023
- 170M6058–170M6073
- 170M6108–170M6123
- 170M6158–170M6173
- 170M6208–170M6223
- 170M6258–170M6273
- 170M6308–170M6323
- 170M6358–170M6373
- 170M6408–170M6423
- 170M6458–170M6473
- 170M6508–170M6523
- 170M6558–170M6573
- 170M6608–170M6623
- 170M6658–170M6673
- 170M6708–170M6723
- 170M6758–170M6771
Treat these as catalog-search groups, not as an indication that every number exists in every market or shares one voltage rating. Check the exact Eaton product page for the current specification and product status.
4. A reliable cross-reference workflow
When an original part number is known, use this process:
- Capture the complete part number and any suffix from the fuse body.
- Open the manufacturer’s page for that exact catalog number.
- Confirm voltage type and rating, rated current and utilization category.
- Check interrupting capacity under the relevant circuit conditions.
- Compare pre-arcing and total-clearing I²t where semiconductor coordination requires it.
- Compare fuse size, terminals, mounting spacing, body dimensions and clearances.
- Confirm indicator and microswitch requirements.
- Obtain approval from the equipment manufacturer or responsible engineer for any alternate.
- Verify price, stock and lead time separately with the supplier.
5. Why close catalog numbers are not proof of equivalence
A fuse’s model number is an identifier, not a complete decoding scheme. Adjacent numbers can differ in rated voltage, current, utilization category, body size, terminal style or indicator arrangement. A product with the correct physical dimensions can still be electrically unsuitable, and a fuse with a matching current rating may not provide the required semiconductor protection.
Do not infer ratings for a catalog group from a single example. Each candidate must be checked against its own manufacturer documentation.

Frequently Asked Questions
What does this 170M cross-reference actually cover?
Selected catalog-number groups across size 1, size 2 and size 3, from 170M3008 through 170M6771. It is a discovery list, not a replacement table.
Can I replace one 170M model with the next number in the sequence?
No. Adjacent numbers can differ in rated voltage, current, category, body size or indicator arrangement, so each candidate needs its own datasheet check.
What should be captured before looking for an alternative?
The complete part number with suffix, voltage type and rating, rated current, utilization category, I2t data, terminal geometry and indicator requirement.
Do all models in a listed group share one rating?
No. A group is a catalog range, not a common specification. Ratings must be read per catalog number.
Where does the approval for a substitute come from?
From the equipment manufacturer or the responsible engineer, after the documented technical review.
