SPP-4E150 Equivalent & Substitute Parts

Part Overview

The SPP-4E150 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 150A at 700V. This component is classified as obsolete, requiring identification of active equivalent parts for continued system support and procurement. The part requires a dedicated holder for installation and is part of the Semitron™ SPP series. Due to its obsolete status, sourcing active alternatives is necessary for maintenance, repair, and new installations.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 170M3664 is identified as an equivalent based on the following critical parameters:

• Voltage Rating Compatibility: Both parts operate at 700V AC, ensuring electrical system compatibility
• Current Rating Proximity: The substitute is rated for 160A, representing a 10A increase from the original 150A specification
• Manufacturer Consistency: Both parts are manufactured by Eaton - Bussmann Electrical Division, maintaining design and quality standards
• Regulatory Compliance: Both parts share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications
• Active Status: The substitute part 170M3664 is active and in stock, addressing the obsolescence of the original SPP-4E150

The substitution is based on electrical parameters (voltage and current ratings) and regulatory alignment. Mounting type differs (bolt mount versus holder requirement), which must be evaluated for specific installation contexts.

Parameter Comparison

Engineering Selection Recommendations

The 170M3664 is an active equivalent for the obsolete SPP-4E150 based on voltage rating alignment (700V) and current rating compatibility (160A versus 150A). Both parts carry identical regulatory classifications (ECCN EAR99, HTSUS 8536.10.0040), confirming compliance equivalence.

Selection of 170M3664 requires evaluation of mounting infrastructure, as the substitute uses bolt mount configuration rather than a holder-based system. The higher current rating (160A) and specified breaking capacity (200kA) provide enhanced performance margins within the same voltage class.

The active product status of 170M3664 ensures ongoing availability and supply chain continuity, addressing the procurement limitations of the obsolete SPP-4E150.

Frequently Asked Questions (FAQ)

Q: Can 170M3664 directly replace SPP-4E150 in existing installations?

A: Electrical compatibility is confirmed through matching 700V voltage ratings and compatible current ratings (160A substitute for 150A original). However, mounting infrastructure must be evaluated, as SPP-4E150 requires a dedicated holder while 170M3664 uses bolt mount configuration.

Q: What is the significance of the 10A current rating increase from 150A to 160A?

A: The substitute part carries a higher current rating within the same voltage class. This represents a performance margin increase and does not create incompatibility with systems designed for 150A operation.

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

A: Yes. Both SPP-4E150 and 170M3664 share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications, confirming regulatory equivalence for export and trade purposes.

Q: Why is the mounting type different between these parts?

A: SPP-4E150 is designed for holder-based installation, while 170M3664 uses bolt mount configuration. This reflects different mechanical design approaches within the Eaton - Bussmann product portfolio. Installation compatibility depends on available mounting infrastructure in the target application.

Q: What does the breaking capacity specification indicate?

A: The 170M3664 breaking capacity of 200kA at rated voltage specifies the maximum fault current the fuse can safely interrupt. This parameter is not provided for SPP-4E150 in available documentation.

Q: Is 170M3664 currently available for procurement?

A: Yes. 170M3664 is classified as active with 1061 pieces in stock, ensuring supply availability. SPP-4E150 is obsolete and no longer actively produced.
