SPP-7F800 Equivalent & Substitute Parts

Part Overview

The SPP-7F800 is an 800A 700V blade fuse link manufactured by Eaton - Bussmann Electrical Division, part of the Semitron™ SPP series. This component is classified as obsolete, requiring identification of active equivalent parts for continued system support and procurement. The fuse link design necessitates a compatible holder for installation, making substitute selection dependent on both electrical ratings and mounting interface compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-7F800 is determined by the following critical parameters:

• Current Rating: 800A (exact match required)
• Voltage Rating: 700V AC (exact match required)
• Manufacturer: Eaton - Bussmann Electrical Division (same manufacturer ensures design compatibility)
• Product Status: Active status required for ongoing availability
• Regulatory Compliance: ECCN EAR99 classification maintained; REACH Unaffected status preserved

The substitute part 170M6712 meets these criteria as an active component with identical electrical ratings (800A, 700VAC) from the same manufacturer. The transition from blade mounting (requires holder) to bolt mount represents a mechanical interface change that must be evaluated within the context of the installation environment.

Parameter Comparison

Engineering Selection Recommendations

The 170M6712 is the designated substitute for the obsolete SPP-7F800 based on electrical equivalence (800A, 700VAC) and manufacturer continuity. The part maintains active product status, ensuring procurement availability and supply chain stability.

Key considerations for selection:

• Electrical Compatibility: Both components are rated for 800A at 700VAC, meeting circuit protection requirements.
• Regulatory Compliance: The 170M6712 carries CE, CSA, and UR approvals, providing broader certification coverage than the obsolete SPP-7F800.
• Mechanical Interface: The transition from blade mounting (holder-dependent) to bolt mount requires evaluation of the installation enclosure. Bolt mount configuration may necessitate mechanical redesign of the mounting structure.
• RoHS Compliance: The 170M6712 is RoHS Compliant, aligning with current environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can the 170M6712 directly replace the SPP-7F800 without modification?

A: Electrical substitution is valid (800A, 700VAC ratings match). However, the mounting interface differs: SPP-7F800 uses blade mounting requiring a holder, while 170M6712 uses bolt mount. Installation compatibility depends on the existing enclosure design and mounting infrastructure.

Q: What are the critical parameters for fuse substitution in this category?

A: Current rating (800A), voltage rating (700VAC), and manufacturer (Eaton - Bussmann Electrical Division) are the primary determinants. Mounting type and physical dimensions are secondary considerations dependent on installation environment.

Q: Why is the SPP-7F800 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 170M6712 represents the active equivalent for ongoing procurement and system support.

Q: Are there compliance differences between these parts?

A: The 170M6712 carries CE, CSA, and UR approvals and is RoHS Compliant. The SPP-7F800 specifications do not document these certifications. Both maintain EAR99 export classification.

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

A: The 170M6712 specifies 200kA breaking capacity at rated voltage, indicating the maximum fault current the fuse can safely interrupt. This parameter was not provided for the SPP-7F800.
