SPP-4F150 Equivalent & Substitute Parts

Part Overview

The SPP-4F150 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 150A at 700V. This component is classified as obsolete, requiring identification of suitable alternatives for ongoing system maintenance and new installations. The obsolete status necessitates sourcing equivalent or substitute components that maintain electrical and mechanical compatibility with existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-4F150 is based on the following critical parameters:

• Voltage Rating: Minimum 700V AC to maintain electrical safety margins
• Current Rating: 150A nominal, with tolerance for rated values within the same protection class
• Mounting Configuration: Physical compatibility with existing holder or mounting infrastructure
• Manufacturer Compliance: REACH and ECCN classification consistency
• Product Availability: Active status to ensure supply chain continuity

The substitute part 170M3714 shares the same manufacturer (Eaton - Bussmann Electrical Division), voltage rating (700VAC), and regulatory classification (ECCN EAR99, HTSUS 8536.10.0040). The current rating difference (160A vs. 150A) and mounting type variation (Bolt Mount vs. Requires Holder) require evaluation based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The 170M3714 is an active product from the same manufacturer with equivalent voltage rating and regulatory classification. Selection of this substitute requires verification of:

• Mechanical compatibility with existing mounting infrastructure, as the SPP-4F150 requires a holder while the 170M3714 uses bolt mount configuration
• Current rating tolerance, as the 170M3714 is rated 160A compared to the 150A specification of the SPP-4F150
• Physical dimensions and form factor compatibility within the application enclosure

The active product status of the 170M3714 ensures ongoing availability and supply chain support compared to the obsolete SPP-4F150.

Frequently Asked Questions (FAQ)

Q: Can the 170M3714 directly replace the SPP-4F150 in existing installations?

A: Direct replacement requires verification of mounting compatibility. The SPP-4F150 requires a dedicated holder, while the 170M3714 uses bolt mount configuration. Physical installation modifications may be necessary.

Q: What is the significance of the current rating difference (150A vs. 160A)?

A: The 170M3714 is rated 10A higher than the SPP-4F150. This difference must be evaluated against circuit protection requirements and load specifications of the application.

Q: Are both parts compliant with the same regulatory standards?

A: Both parts share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications. The 170M3714 carries CSA and UR approvals; regulatory compliance verification for your specific application is required.

Q: What is the breaking capacity specification?

A: The 170M3714 specifies 200kA breaking capacity at rated voltage. The SPP-4F150 breaking capacity is not provided in available documentation.

Q: How do the physical dimensions compare?

A: The 170M3714 dimensions are 1.969" L x 1.772" W x 2.323" H (50.00mm x 45.00mm x 59.00mm). SPP-4F150 dimensions are not specified. Enclosure space verification is necessary before substitution.
