SPP-4M150 Equivalent & Substitute Parts

Part Overview

The SPP-4M150 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 150A at 700V operation. This component is classified as obsolete and requires a holder for installation. Due to its obsolete status, identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SPP-4M150 is determined by the following critical parameters:

• Current Rating: 150A nominal operation
• Voltage Rating: 700V AC operation
• Mounting Configuration: Requires holder installation
• Manufacturer: Eaton - Bussmann Electrical Division (same manufacturer ensures design compatibility)
• Regulatory Compliance: REACH and ECCN classification alignment

The substitute part 170M3564 shares the same manufacturer, voltage rating (700VAC), mounting requirement (holder-based), and regulatory classification. While the current rating differs at 160A, this represents the closest available active product within the Eaton - Bussmann portfolio that maintains electrical and mechanical compatibility with the original SPP-4M150 specification.

Parameter Comparison

Engineering Selection Recommendations

The 170M3564 is the designated substitute for the obsolete SPP-4M150. Both components are manufactured by Eaton - Bussmann Electrical Division and share identical voltage ratings (700V), mounting requirements (holder-based installation), and regulatory classifications (ECCN EAR99, HTSUS 8536.10.0040).

The 170M3564 holds active product status, ensuring ongoing availability and supply chain continuity. The component is RoHS compliant and carries CSA and UR approvals, meeting current regulatory requirements. The 160A current rating of the 170M3564 represents the closest available specification to the original 150A rating within the active product line.

Frequently Asked Questions (FAQ)

Q: Can the 170M3564 directly replace the SPP-4M150 in existing installations?

A: Both components require holder installation and operate at 700V. The 170M3564 is rated for 160A compared to the SPP-4M150's 150A rating. Compatibility depends on the specific circuit design and holder configuration. Verify that the holder accommodates the 170M3564's rectangular blade package format.

Q: What is the difference between the fuse types listed?

A: The SPP-4M150 is classified as a fuse link, while the 170M3564 is a square fuse. Both require holder installation and operate within the same voltage class. The physical form factor differs, requiring verification of holder compatibility.

Q: Are there regulatory or compliance differences between these parts?

A: Both components share the same ECCN (EAR99) and HTSUS classification (8536.10.0040). The 170M3564 is RoHS compliant and carries CSA and UR approvals. The SPP-4M150 is REACH unaffected. Both meet export and regulatory requirements for their respective classifications.

Q: What is the significance of the 200kA breaking capacity specification?

A: The 170M3564 specifies a breaking capacity of 200kA at rated voltage. This parameter indicates the maximum fault current the fuse can safely interrupt. This specification is provided for the substitute part but is not available in the original SPP-4M150 data.

Q: How does the melting I²t value affect substitution?

A: The 170M3564 specifies a melting I²t of 1100. This parameter characterizes the thermal energy required to melt the fuse element and is used in circuit protection calculations. This specification is provided for the substitute part but is not available in the original SPP-4M150 data.
