SPP-5H225 Equivalent & Substitute Parts

Part Overview

The SPP-5H225 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 225A at 700V with blade mounting. This component is classified as obsolete, requiring identification of functionally equivalent alternatives for continued system support and procurement planning. Substitute parts must maintain electrical compatibility within the 700V system voltage class while accommodating the mechanical mounting requirements of the original application.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-5H225 is based on the following critical parameters:

• Voltage Rating: Substitute must operate at 700V AC to maintain system compatibility
• Current Rating: Substitute must provide equivalent or higher current capacity (225A minimum)
• Mounting Configuration: Substitute must accommodate the electrical distribution architecture of the original application
• Manufacturer Continuity: Eaton - Bussmann Electrical Division maintains product line compatibility across the Semitron™ series and related industrial fuse offerings
• Regulatory Compliance: REACH and ECCN classifications must align with the original specification

The identified substitute, 170M4759, meets these criteria through equivalent voltage rating, higher current capacity, and active product status within the same manufacturer ecosystem.

Parameter Comparison

Engineering Selection Recommendations

The 170M4759 is the designated substitute for the obsolete SPP-5H225 based on the following factors:

• Active Product Status: The 170M4759 maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Voltage Compatibility: Both components operate at 700V, maintaining electrical system requirements
• Current Capacity: The 170M4759 provides 250A rating, exceeding the original 225A specification and supporting system margin
• Regulatory Alignment: Both components carry EAR99 ECCN classification and identical HTSUS codes (8536.10.0040), confirming regulatory equivalence
• Certification Coverage: The 170M4759 holds CE, CSA, and UR approvals, providing broader compliance documentation than the obsolete original

Mounting configuration differences (blade holder versus bolt mount) require mechanical integration assessment within the specific application context.

Frequently Asked Questions (FAQ)

Q: Can the 170M4759 directly replace the SPP-5H225 without modification?

A: Electrical compatibility is confirmed through matching 700V ratings and equivalent current capacity. Mechanical integration requires evaluation of the mounting interface, as the SPP-5H225 uses a holder-based configuration while the 170M4759 employs bolt mounting.

Q: What is the significance of the higher 250A rating on the 170M4759?

A: The increased current rating provides system margin and does not create incompatibility with the original 225A circuit design. The fuse will operate within its rated parameters when protecting a 225A circuit.

Q: Are there compliance differences between these components?

A: Both components share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications. The 170M4759 provides documented CE, CSA, and UR approvals, while the SPP-5H225 approval documentation is not specified in the available data.

Q: What does "Requires Holder" mean for the SPP-5H225?

A: This indicates the fuse link requires a separate holder assembly for installation. The 170M4759 uses direct bolt mounting, which may require different installation hardware.

Q: Is the 170M4759 suitable for the same 700V electrical system?

A: Yes. The 170M4759 is rated for 700 VAC operation, matching the original system voltage specification.
