Key Parameters

Substitute Part Grouping Explanation

The substitute part 170M6762 is qualified as an equivalent based on the following critical parameters:

• Current Rating: Both parts are rated for 800A
• Voltage Rating: Both parts are rated for 700V AC
• Manufacturer: Both are manufactured by Eaton - Bussmann Electrical Division, ensuring consistent design standards and quality
• Regulatory Compliance: Both parts carry ECCN EAR99 classification and HTSUS 8536.10.0040 code
• Electrical Performance: The substitute provides a breaking capacity of 200kA at rated voltage with a melting I²t of 69500, meeting industrial protection requirements

The primary difference is the mounting configuration: the SPP-7H800 requires a separate holder, while the 170M6762 features bolt mount capability. This distinction does not affect electrical equivalence but impacts installation methodology.

Parameter Comparison

Engineering Selection Recommendations

The 170M6762 is the qualified substitute for the obsolete SPP-7H800 based on electrical equivalence. Both components share identical current and voltage ratings from the same manufacturer, ensuring functional compatibility in 800A 700V applications.

The 170M6762 offers the advantage of active product status, meaning it remains in current production and is readily available. The part carries CE, CSA, and UR approvals, providing broader regulatory acceptance across multiple jurisdictions. Additionally, RoHS compliance of the 170M6762 aligns with modern environmental standards.

Installation considerations must account for the mounting difference: the SPP-7H800 integrates with a separate holder assembly, while the 170M6762 employs direct bolt mount configuration. System design must accommodate this mechanical distinction during component replacement.

Frequently Asked Questions (FAQ)

Q: Can the 170M6762 directly replace the SPP-7H800 in existing installations?

A: Electrical substitution is valid due to matching current and voltage ratings. However, mechanical integration requires verification. The SPP-7H800 uses a holder-based mounting system, while the 170M6762 uses bolt mount. Installation feasibility depends on the existing mechanical framework.

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

A: Current rating (800A), voltage rating (700V), and manufacturer consistency are the primary determinants. Both parts meet these criteria. Secondary considerations include breaking capacity, melting I²t characteristics, and mounting compatibility with the system design.

Q: Why is the SPP-7H800 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 170M6762 represents the current equivalent offering from Eaton - Bussmann Electrical Division for this application class.

Q: Are there compliance differences between the two parts?

A: Both parts share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications. The 170M6762 carries additional approvals (CE, CSA, UR) and RoHS compliance, reflecting current regulatory requirements.

Q: What is the significance of the melting I²t value?

A: The melting I²t of 69500 for the 170M6762 defines the thermal energy required to melt the fuse element. This parameter ensures predictable response characteristics under fault conditions and is essential for system protection coordination.
