Key Parameters

Substitute Part Grouping Explanation

The 170M3659 serves as an equivalent substitute based on the following critical parameters:

• Current Rating: Both parts rated at 50A
• Voltage Rating: Both parts rated at 700V AC
• Manufacturer: Both manufactured by Eaton - Bussmann Electrical Division
• Regulatory Compliance: Both carry ECCN EAR99 classification and HTSUS 8536.10.0040 code

The primary difference is mounting configuration: SPP-4E50 requires a separate holder, while 170M3659 features bolt mount capability. Both maintain equivalent electrical performance within the specified current and voltage parameters.

Parameter Comparison

Engineering Selection Recommendations

The 170M3659 is the active equivalent for the obsolete SPP-4E50. Selection is based on:

• Identical current and voltage ratings (50A, 700V)
• Same manufacturer lineage (Eaton - Bussmann Electrical Division)
• Active product status ensuring ongoing availability and support
• RoHS compliance and CSA/UR approvals on the substitute part
• Equivalent regulatory classification (ECCN EAR99)

Installation requires evaluation of mounting configuration compatibility. The 170M3659 bolt mount design differs from the SPP-4E50 holder requirement; mechanical integration must be assessed for the specific application.

Frequently Asked Questions (FAQ)

Q: Can 170M3659 directly replace SPP-4E50 in existing installations?

A: Both parts share identical electrical ratings (50A, 700V). Compatibility depends on mechanical mounting configuration. SPP-4E50 requires a separate holder, while 170M3659 uses bolt mount. Verify that your installation can accommodate the bolt mount design before substitution.
