Key Parameters

Substitute Part Grouping Explanation

The substitute part 170M6761 is identified as functionally equivalent based on the following critical parameters:

• Current Rating: Both parts are rated for 700A
• Voltage Rating: Both parts are rated for 700V AC
• Manufacturer: Both are manufactured by Eaton - Bussmann Electrical Division
• Compliance & Certifications: Both carry ECCN EAR99 and HTSUS 8536.10.0040 classifications
• REACH Compliance: Both are REACH Unaffected

The primary difference lies in the mounting configuration: the SPP-7H700 requires a separate holder, while the 170M6761 features bolt mount capability. Both configurations serve the same electrical protection function at identical electrical ratings.

Parameter Comparison

Engineering Selection Recommendations

The 170M6761 serves as the active equivalent for the obsolete SPP-7H700. Both components share identical electrical ratings (700A, 700V) and are manufactured by the same supplier, ensuring functional compatibility in circuits designed for the original part.

The 170M6761 carries active product status and RoHS compliance, making it suitable for new installations and systems requiring current regulatory adherence. The transition from holder-based mounting to bolt mount represents a mechanical design evolution that does not affect electrical performance.

Selection of the 170M6761 is appropriate when the circuit design accommodates bolt mount installation. Compliance certifications (CE, CSA, UR) and the specified breaking capacity of 200kA confirm suitability for industrial and electrical applications at the rated voltage and current levels.

Frequently Asked Questions (FAQ)

Q: Can the 170M6761 directly replace the SPP-7H700 in existing installations?

A: Electrical compatibility is confirmed due to identical current and voltage ratings. Mechanical compatibility depends on the installation configuration. The SPP-7H700 requires a separate holder, while the 170M6761 uses bolt mount. Verify that the circuit design or enclosure can accommodate bolt mount installation before substitution.

Q: What is the significance of the different fuse types (Blade vs. Square)?

A: The fuse type designation reflects the physical form factor. Both configurations are rated identically for 700A at 700V and serve the same protective function. The form factor difference is a mechanical consideration related to mounting hardware and enclosure design, not electrical performance.

Q: Why is the SPP-7H700 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 170M6761 represents the current-generation equivalent, offering the same electrical protection with modern manufacturing standards and compliance certifications.

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

A: Both parts share the same ECCN (EAR99) and HTSUS (8536.10.0040) classifications. The 170M6761 carries RoHS compliance and holds CE, CSA, and UR certifications, reflecting its active product status and suitability for current regulatory environments.

Q: What does the Breaking Capacity specification mean for the 170M6761?

A: The breaking capacity of 200kA indicates the maximum fault current the fuse can safely interrupt at the rated voltage (700 VAC). This specification confirms the fuse's ability to protect circuits under high-fault-current conditions.
