Key Parameters

Substitute Part Grouping Explanation

The 170M4560 is identified as a functional substitute based on the following alignment of critical electrical and mechanical parameters:

• Both components are manufactured by Eaton - Bussmann Electrical Division
• Both require external holder mounting
• Both operate within compatible voltage and current specifications (170M4560: 315A at 690V)
• Both share the same HTSUS classification (8536.10.0040), indicating equivalent tariff categorization
• Both are classified under fuse link product categories with holder-dependent installation

The 170M4560 represents an active product alternative, addressing the obsolescence status of the SPP-5M300 while maintaining electrical and mechanical compatibility within the Eaton fuse portfolio.

Parameter Comparison

Engineering Selection Recommendations

The 170M4560 is an active product offering from the same manufacturer, providing continuity for applications previously served by the obsolete SPP-5M300. The substitute maintains holder-dependent mounting architecture and operates within the same electrical classification range. The 170M4560 carries RoHS compliance certification, meeting current regulatory requirements for new installations and replacements. Both components share identical HTSUS tariff classification, confirming their functional equivalence within electrical protection systems.

Frequently Asked Questions (FAQ)

Q: Can the 170M4560 directly replace the SPP-5M300 in existing installations?

A: Both components require external holder mounting and operate within compatible voltage and current specifications. Verification of holder compatibility with the 170M4560's square form factor is necessary before installation.

Q: What is the significance of the current rating difference (300A vs. 315A)?

A: The 170M4560 operates at a higher current rating (315A) compared to the SPP-5M300 (300A). System design parameters must confirm that this rating difference is acceptable for the intended application.

Q: Does the 170M4560 have different compliance certifications?

A: The 170M4560 carries RoHS compliance certification, whereas the SPP-5M300 is listed as REACH Unaffected. Both components share the same HTSUS classification, confirming regulatory alignment for electrical protection components.

Q: What is the difference between "Fuse Link" and "Square" fuse types?

A: The SPP-5M300 is classified as a Fuse Link type, while the 170M4560 is a Square type fuse. Physical form factor differences require confirmation of holder compatibility before substitution.

Q: Is the fast blow response time of the 170M4560 compatible with SPP-5M300 applications?

A: The SPP-5M300 response time is not specified in available documentation. Application requirements must be evaluated to confirm that fast blow response characteristics are suitable for the intended circuit protection function.
