SPP-4E80 Equivalent & Substitute Parts

Part Overview

The SPP-4E80 is an 80A 700V blade fuse link manufactured by Eaton - Bussmann Electrical Division, part of the Semitron™ SPP series. 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 operation in electrical and industrial applications where 80A 700V protection is required.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 170M3661 is qualified as an equivalent based on the following critical parameters:

• Current Rating Match: Both parts are rated for 80A
• Voltage Rating Match: Both parts are rated for 700V AC
• Manufacturer Consistency: Both parts are manufactured by Eaton - Bussmann Electrical Division, ensuring design compatibility and quality standards
• Functional Equivalence: Both parts serve the same protective function in electrical circuits
• Regulatory Compliance: Both parts share the same HTSUS code (8536.10.0040) and ECCN classification (EAR99)

The primary difference is the mounting configuration: SPP-4E80 uses a blade fuse link design requiring a holder, while 170M3661 uses a square bolt mount design. This distinction requires verification of the installation environment and holder compatibility before substitution.

Parameter Comparison

Engineering Selection Recommendations

The 170M3661 is an active product substitute for the obsolete SPP-4E80, sharing identical electrical ratings (80A, 700V) and manufacturer origin. The substitute part carries CSA and UR approvals and is RoHS compliant, providing enhanced regulatory compliance compared to the original part.

The primary consideration for substitution is the mechanical interface: the SPP-4E80 blade fuse link requires a specific holder, while the 170M3661 uses a square bolt mount configuration. Substitution is viable only when the installation environment can accommodate the bolt mount design or when appropriate mechanical adapters are available.

The 170M3661 provides a 200kA breaking capacity at rated voltage and a melting I²t value of 185, specifications not provided for the original part. These parameters should be verified against circuit protection requirements before final selection.

Frequently Asked Questions (FAQ)

Q: Can 170M3661 directly replace SPP-4E80 without modification?

A: Both parts share identical electrical ratings (80A, 700V) and are manufactured by the same company. However, the mounting interface differs: SPP-4E80 uses a blade fuse link design requiring a holder, while 170M3661 uses a square bolt mount. Direct replacement requires mechanical compatibility with the installation environment.

Q: What are the key parameters that make these parts equivalent?

A: Current rating (80A), voltage rating (700V), manufacturer (Eaton - Bussmann Electrical Division), and regulatory classification (ECCN EAR99, HTSUS 8536.10.0040) are the critical equivalence parameters.

Q: Why is SPP-4E80 obsolete?

A: Product status information indicates obsolescence. The active substitute 170M3661 provides equivalent electrical protection with enhanced compliance certifications (CSA, UR, RoHS).

Q: Are there any compliance differences between the two parts?

A: The 170M3661 carries CSA and UR approvals and is RoHS compliant. The SPP-4E80 is REACH unaffected. Both share the same ECCN and HTSUS classifications.

Q: What is the significance of the 200kA breaking capacity specification?

A: The 170M3661 specifies a 200kA breaking capacity at rated voltage. This parameter defines the maximum fault current the fuse can safely interrupt. Verify this specification meets circuit protection requirements before substitution.

Q: How do the physical dimensions affect substitution?

A: The 170M3661 dimensions are 1.969" L x 1.772" W x 2.323" H (50.00mm x 45.00mm x 59.00mm). Physical space availability in the installation environment must be confirmed before substitution.
