Key Parameters

Substitute Part Grouping Explanation

Substitution for the SPP-6K350 is determined by the following critical parameters:

• Current Rating: 350A
• Voltage Rating: 700V AC
• Mounting Type: Requires Holder
• Regulatory Compliance: REACH Unaffected, EAR99 classification

The substitute part 170M4511 meets these core electrical and mechanical requirements. Both components share identical current and voltage ratings, require holder-based mounting, and maintain equivalent regulatory compliance status. The substitute is classified as active product status, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The 170M4511 serves as the primary substitute for the obsolete SPP-6K350. Both components are manufactured by Eaton - Bussmann Electrical Division and share identical electrical specifications: 350A current rating and 700V AC voltage rating. Both require holder-based mounting and maintain equivalent regulatory classifications under EAR99 and HTSUS 8536.10.0040.

The 170M4511 is classified as active product status, providing assured long-term availability and manufacturer support. This component carries CSA and UR approvals, indicating compliance with recognized safety standards. The substitute features a breaking capacity of 200kA at rated voltage and includes an indicating function for operational status visibility.

Physical form factor differences exist between the stud-type SPP-6K350 and the square-type 170M4511. Dimensional specifications for the 170M4511 are 1.969" L x 2.087" W x 2.717" H (50.00mm x 53.00mm x 69.00mm). Holder compatibility must be verified during integration to ensure mechanical fit within existing installations.

Frequently Asked Questions (FAQ)

Q: Can the 170M4511 directly replace the SPP-6K350 in all applications?

A: Both components share identical electrical ratings (350A, 700V AC) and mounting requirements (holder-based installation). However, physical form factor differences exist: the SPP-6K350 is stud-type while the 170M4511 is square-type. Holder compatibility must be confirmed before substitution.

Q: What is the significance of the active product status for the 170M4511?

A: Active product status indicates the component is currently manufactured and supported by Eaton - Bussmann Electrical Division. This ensures availability for procurement and provides access to manufacturer technical support and documentation.

Q: Are there regulatory compliance differences between these components?

A: Both components share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications. The 170M4511 carries CSA and UR approvals. The SPP-6K350 is REACH Unaffected. These regulatory statuses are compatible for equivalent application use.

Q: What is the breaking capacity specification for the substitute part?

A: The 170M4511 has a breaking capacity of 200kA at rated voltage (700V AC). This specification defines the maximum fault current the fuse can safely interrupt.

Q: How do the physical dimensions affect installation?

A: The 170M4511 measures 1.969" L x 2.087" W x 2.717" H (50.00mm x 53.00mm x 69.00mm). Existing holder installations designed for the stud-type SPP-6K350 must be evaluated for mechanical compatibility with the square-type form factor before deployment.
