Key Parameters

Substitute Part Grouping Explanation

The substitute part 170M4662 is identified based on the following electrical and mechanical parameters:

• Voltage Rating Compatibility: Both parts operate at 700V AC, ensuring electrical system compatibility
• Current Rating Proximity: The substitute is rated for 400A, representing a higher current capacity than the original 375A specification
• Manufacturer Continuity: Both components are manufactured by Eaton - Bussmann Electrical Division, ensuring design and quality consistency
• Regulatory Compliance: Both parts share identical ECCN (EAR99) and HTSUS classifications, confirming regulatory equivalence
• Mounting Architecture: The substitute utilizes bolt mount configuration versus the original blade holder requirement, necessitating mechanical interface adaptation

Parameter Comparison

Engineering Selection Recommendations

The 170M4662 serves as an active substitute for the obsolete SPP-5E375 based on electrical parameter alignment and manufacturer continuity. The substitute maintains 700V AC voltage compatibility and provides increased current capacity at 400A. Both components share identical regulatory classifications (ECCN EAR99, HTSUS 8536.10.0040), confirming compliance equivalence.

The primary consideration for implementation is the mechanical interface change from blade holder mounting to bolt mount configuration. System integration requires verification that the electrical enclosure or fuse holder assembly accommodates the rectangular bolt mount form factor (1.969" L x 2.087" W x 2.717" H).

The substitute part carries active product status with documented approvals from CE, CSA, and UR agencies, providing assurance of current manufacturing standards and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the 170M4662 directly replace the SPP-5E375 without modification?

A: Electrical compatibility is confirmed through matching 700V AC voltage ratings. However, mechanical compatibility requires assessment of the mounting interface. The SPP-5E375 uses blade holder mounting, while the 170M4662 requires bolt mount configuration. The electrical enclosure or fuse holder assembly must support rectangular bolt mount attachment.

Q: What is the significance of the current rating difference (375A vs. 400A)?

A: The substitute part is rated for 25A higher current capacity. This represents a higher protective threshold and must be evaluated against the specific circuit protection requirements of the application.

Q: Why is the SPP-5E375 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 170M4662 is an active product, ensuring availability for new installations and ongoing system maintenance.

Q: Are both parts subject to the same regulatory requirements?

A: Both components share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications, confirming equivalent regulatory treatment. The substitute carries documented approvals from CE, CSA, and UR agencies.

Q: What is the melting I²t value for the SPP-5E375?

A: This parameter is not provided in the available technical documentation for the main part. The substitute part specifies a melting I²t of 13500.
