SPP-6F800 Equivalent & Substitute Parts

Part Overview

The SPP-6F800 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 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SPP-6F800 is determined by the following critical parameters:

• Current Rating: 800A (primary electrical requirement)
• Voltage Rating: 700V DC or equivalent AC rating (electrical compatibility)
• Manufacturer: Eaton - Bussmann Electrical Division (product line continuity)
• Mounting Configuration: Physical form factor and installation method
• Product Status: Active status preferred for ongoing availability

The substitute part 170M5714 shares the same current rating (800A) and manufacturer. However, the voltage rating differs: 170M5714 is rated for 70 VAC, which is significantly lower than the SPP-6F800's 700V rating. This voltage difference is a critical parameter that must be evaluated against the specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The 170M5714 is an active product from the same manufacturer, providing improved availability compared to the obsolete SPP-6F800. However, the voltage rating difference (70 VAC versus 700V) represents a fundamental electrical parameter that must align with the application circuit requirements.

Selection of 170M5714 as a substitute is contingent upon:

• Verification that the application circuit operates at 70 VAC or lower
• Confirmation that bolt mount installation is compatible with the existing system
• Acceptance of the rectangular blade form factor in place of the original fuse link configuration
• Compliance with CE, CSA, and UR certifications meeting the application's regulatory requirements

If the application requires 700V operation, alternative parts from Eaton - Bussmann Electrical Division with matching voltage ratings must be sourced.

Frequently Asked Questions (FAQ)

Q: Can 170M5714 directly replace SPP-6F800 in all applications?

A: No. The voltage rating difference (70 VAC versus 700V) is a critical electrical parameter. Direct substitution is only valid if the application circuit operates at 70 VAC or lower. Voltage mismatch can result in component failure or safety hazards.

Q: What is the primary advantage of 170M5714 over SPP-6F800?

A: The 170M5714 is an active product with current manufacturing and distribution, whereas SPP-6F800 is obsolete. Both share the same 800A current rating and manufacturer. The 170M5714 also provides documented breaking capacity (200kA) and RoHS compliance.

Q: Are the mounting types interchangeable?

A: No. SPP-6F800 requires a holder for installation, while 170M5714 uses bolt mount configuration. The physical installation method differs and must be evaluated against the existing system design.

Q: What certifications does 170M5714 carry?

A: 170M5714 holds CE, CSA, and UR approvals. These certifications should be verified against the application's regulatory requirements.

Q: If 170M5714 is not suitable, what should be done?

A: Contact Eaton - Bussmann Electrical Division to identify alternative 800A fuse products with 700V voltage rating and compatible mounting configurations for the specific application.
