Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-7H1200 is based on the following critical electrical and mechanical parameters:

Voltage Rating Compatibility: Both the main part and substitute must operate at 700V AC to maintain circuit protection integrity.

Current Rating Tolerance: The substitute part (170M6766) is rated at 1.25kA, representing a 4.2% increase over the original 1.2kA specification. This elevated rating remains within acceptable tolerance for fuse substitution in industrial electrical applications where the substitute provides equivalent or enhanced protection characteristics.

Mounting Configuration: The original SPP-7H1200 requires a blade-type holder. The substitute 170M6766 features bolt mount configuration with rectangular blade package compatibility, enabling installation in systems designed for blade-mount fuse holders.

Manufacturer Consistency: Both components are manufactured by Eaton - Bussmann Electrical Division, ensuring design philosophy and quality standards alignment.

Regulatory Compliance: The substitute maintains REACH compliance and EAR99 ECCN classification, matching the regulatory framework of the original component.

Parameter Comparison

Engineering Selection Recommendations

The 170M6766 serves as the primary substitute for the obsolete SPP-7H1200 based on the following criteria:

Electrical Compatibility: Both components operate at 700V AC with current ratings within 4.2% tolerance (1.2kA vs. 1.25kA), maintaining circuit protection function in equivalent electrical systems.

Active Product Status: The 170M6766 is classified as active, ensuring ongoing availability and supply chain reliability compared to the obsolete SPP-7H1200.

Regulatory Alignment: Both components share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications, confirming regulatory equivalence for procurement and deployment.

Certification Coverage: The 170M6766 carries CE, CSA, and UR approvals, providing comprehensive third-party validation for industrial and electrical applications.

Mechanical Integration: The rectangular blade package configuration of the 170M6766 is compatible with standard blade-mount fuse holder systems, enabling direct installation in existing SPP-7H1200 applications.

Frequently Asked Questions (FAQ)

Q: Can the 170M6766 directly replace the SPP-7H1200 in all applications?

A: The 170M6766 is electrically and mechanically compatible for systems designed for 700V AC, 1.2kA to 1.25kA fuse protection. Verify that the existing fuse holder accommodates the rectangular blade package configuration of the substitute.

Q: What is the significance of the 1.25kA rating on the 170M6766 compared to the 1.2kA original?

A: The 1.25kA rating represents a 4.2% increase in current capacity. This elevated rating provides equivalent or enhanced circuit protection and is acceptable for substitution in industrial electrical applications where the original 1.2kA specification is required.

Q: Are there differences in breaking capacity between these components?

A: The 170M6766 specifies a breaking capacity of 200kA at rated voltage. The SPP-7H1200 breaking capacity is not provided in available documentation. Confirm that the 200kA breaking capacity of the substitute meets or exceeds the requirements of your specific circuit protection application.

Q: What mounting differences exist between the SPP-7H1200 and 170M6766?

A: The SPP-7H1200 requires a blade-type holder for mounting. The 170M6766 features bolt mount configuration with rectangular blade package compatibility, enabling installation in standard blade-mount fuse holder systems.

Q: Is the 170M6766 RoHS compliant?

A: Yes, the 170M6766 is RoHS compliant. The SPP-7H1200 RoHS status is not specified in available data.

Q: What certifications does the 170M6766 carry?

A: The 170M6766 holds CE, CSA, and UR approvals, providing comprehensive third-party validation for industrial and electrical applications.
