SPP-6E500 Equivalent & Substitute Parts

Part Overview

The SPP-6E500 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 500A at 700V operation. This component is classified as obsolete, requiring identification of active equivalent parts for continued system support and procurement. The fuse link design necessitates use with a compatible holder assembly. Due to its obsolete status, sourcing equivalent models with identical or compatible electrical and mechanical characteristics is essential for maintenance and replacement applications.

Key Parameters

Substitute Part Grouping Explanation

The 170M5660 qualifies as an equivalent substitute based on the following critical parameters:

• Current Rating Match: Both parts are rated for 500A operation
• Voltage Rating Match: Both parts are rated for 700V AC operation
• Manufacturer Consistency: Both manufactured by Eaton - Bussmann Electrical Division
• Regulatory Compliance: Both carry identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications
• Mounting Compatibility: The 170M5660 features bolt mount capability, providing mechanical compatibility within Eaton's fuse system architecture

The primary distinction lies in form factor: the SPP-6E500 is a blade-type fuse link requiring external holder, while the 170M5660 is a rectangular bolt-mount fuse with integrated mounting provisions. Both designs accommodate the same electrical load parameters and voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

The 170M5660 is the designated equivalent for SPP-6E500 replacement applications. Selection rationale:

• Active Product Status: The 170M5660 maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Electrical Equivalence: Identical 500A and 700V ratings ensure direct functional replacement in circuit protection applications
• Regulatory Alignment: Both parts share identical ECCN and HTSUS classifications, maintaining compliance with export and tariff requirements
• Certification Coverage: The 170M5660 carries CE, CSA, and UR approvals, providing comprehensive standards compliance for industrial and electrical applications
• Mechanical Integration: Bolt mount design of the 170M5660 provides simplified installation compared to the holder-dependent SPP-6E500 architecture

Installation requires verification that the receiving circuit or equipment accommodates the rectangular bolt-mount form factor of the 170M5660.

Frequently Asked Questions (FAQ)

Q: Can the 170M5660 directly replace the SPP-6E500 in existing installations?

A: Electrical compatibility is confirmed through matching 500A and 700V ratings. Mechanical compatibility depends on the mounting infrastructure. The SPP-6E500 requires a separate holder assembly, while the 170M5660 features integrated bolt-mount provisions. Equipment designed for blade-type fuse links may require adapter or redesign for bolt-mount integration.

Q: What are the key parameters that determine substitution eligibility?

A: Current rating (500A), voltage rating (700V), and manufacturer (Eaton - Bussmann Electrical Division) are the primary substitution criteria. Both parts meet these specifications. Secondary considerations include breaking capacity (200kA for 170M5660) and melting I²t (21500 for 170M5660), which define performance characteristics under fault conditions.

Q: Why is the SPP-6E500 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 170M5660 represents the active equivalent within Eaton's current product portfolio, offering equivalent electrical performance with modern manufacturing and certification standards.

Q: Are there packaging or inventory considerations for the 170M5660?

A: The 170M5660 is supplied in bulk packaging with 1105 pieces available in new original stock. The SPP-6E500 is no longer in active production, with remaining inventory at 973 pieces. For new designs or long-term applications, the 170M5660 is the recommended selection.

Q: What certifications apply to the 170M5660?

A: The 170M5660 carries CE, CSA, and UR approvals, meeting international standards for electrical safety and performance. These certifications align with industrial and electrical application requirements.
