Key Parameters

Substitute Part Grouping Explanation

The substitute part 170M3669 is qualified as an equivalent based on the following critical parameters:

• Current Rating: Both parts are rated for 400A
• Voltage Rating: Both parts are rated for 700V AC
• Manufacturer: Both are manufactured by Eaton - Bussmann Electrical Division
• Compliance: Both carry ECCN EAR99 classification and HTSUS 8536.10.0040 code
• Regulatory Status: Both are REACH Unaffected

The primary difference is the mounting configuration: the SPP-4E400 requires an external holder, while the 170M3669 features bolt mount capability. This distinction does not affect electrical equivalency but requires mechanical integration assessment during installation.

Parameter Comparison

Engineering Selection Recommendations

The 170M3669 is an active, in-stock substitute for the obsolete SPP-4E400. Both components share identical electrical ratings (400A, 700V AC) and are manufactured by the same supplier. The 170M3669 carries RoHS compliance and provides documented breaking capacity (200kA) and melting I²t (15000) specifications.

Selection of the 170M3669 requires verification that the bolt mount configuration is compatible with the existing installation framework. The transition from a holder-based design to a bolt mount design necessitates mechanical integration assessment specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the 170M3669 directly replace the SPP-4E400 in all applications?

A: Both parts share identical electrical specifications (400A, 700V AC) and are manufactured by Eaton - Bussmann Electrical Division. However, the mounting configuration differs: SPP-4E400 requires an external holder, while 170M3669 uses bolt mount. Compatibility depends on the mechanical design of the installation.

Q: What is the significance of the obsolete status of SPP-4E400?

A: Obsolete status indicates the part is no longer manufactured. The 170M3669 is an active product with current manufacturing support, inventory availability, and documented specifications including RoHS compliance.

Q: Are there electrical performance differences between these parts?

A: Both parts are rated for 400A at 700V AC. The 170M3669 provides specified breaking capacity (200kA) and melting I²t (15000), which are not documented for the SPP-4E400.

Q: What compliance certifications apply to both parts?

A: Both parts carry ECCN EAR99 classification and HTSUS 8536.10.0040 code. The 170M3669 additionally carries RoHS compliance certification.
