SPP-6E800 Equivalent & Substitute Parts

Part Overview

The SPP-6E800 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 800A at 700V operation. This component is classified as obsolete and requires a holder for installation. Due to its obsolete status, identifying equivalent substitute parts is essential for system maintenance, repair, and continued operational support where original inventory is depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-6E800 is determined by the following critical electrical and mechanical parameters:

• Current Rating: 800A (exact match required)
• Voltage Rating: 700V AC (exact match required)
• Manufacturer: Eaton - Bussmann Electrical Division (same manufacturer ensures design compatibility)
• Regulatory Compliance: REACH Unaffected and EAR99 classification maintained
• Mounting Configuration: Physical form factor and installation method must accommodate existing holder or mounting infrastructure

The substitute part 170M5664 satisfies these criteria through equivalent electrical ratings and compliance certifications, though with a different physical form factor (square bolt mount versus blade link).

Parameter Comparison

Engineering Selection Recommendations

The 170M5664 serves as the active equivalent for the obsolete SPP-6E800 based on:

• Electrical Equivalence: Both components are rated 800A at 700V AC, meeting identical circuit protection requirements
• Regulatory Alignment: Both maintain EAR99 classification and identical HTSUS coding (8536.10.0040)
• Product Status: The 170M5664 is active and currently in production, ensuring long-term availability and supply chain continuity
• Compliance Certifications: The 170M5664 carries CE, CSA, and UR approvals, with RoHS compliance confirmed

Installation Consideration: The 170M5664 employs bolt mount configuration versus the blade link design of the SPP-6E800. Physical mounting infrastructure must be evaluated for compatibility before deployment.

Frequently Asked Questions (FAQ)

Q: Can the 170M5664 directly replace the SPP-6E800 in existing installations?

A: Electrical compatibility is confirmed through identical 800A and 700V ratings. However, the mounting method differs (bolt mount versus blade link holder). Physical installation compatibility must be assessed based on existing holder or mounting infrastructure.

Q: What is the significance of the SPP-6E800 being classified as obsolete?

A: Obsolete status indicates the manufacturer no longer produces this component. The 170M5664 is the active equivalent and is recommended for new procurement and long-term system support.

Q: Are there compliance differences between these two parts?

A: Both components share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications. The 170M5664 provides additional certifications (CE, CSA, UR) and RoHS compliance confirmation.

Q: What does the Breaking Capacity specification mean for the 170M5664?

A: The 200kA breaking capacity at rated voltage indicates the maximum fault current the fuse can safely interrupt. This specification is provided for the 170M5664 but not documented for the SPP-6E800.

Q: Is the 170M5664 suitable for the same applications as the SPP-6E800?

A: Yes, both components are designed for electrical and industrial applications requiring 800A protection at 700V AC. The 170M5664 includes indicating features for operational status monitoring.
