SPP-5M600 Equivalent & Substitute Parts

Part Overview

The SPP-5M600 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 600A at 700V operation. This component is classified as obsolete, requiring identification of active equivalent parts for continued system support and procurement. The part operates as a stud-mounted fuse link within the Semitron™ SPP series and necessitates a compatible holder for installation. Due to its obsolete status, substitute parts with equivalent electrical and mechanical characteristics are required for system maintenance and new installations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SPP-5M600 are identified based on the following critical parameters: manufacturer (Eaton - Bussmann Electrical Division), mounting requirement (holder-based installation), voltage rating compatibility (700V class), and current rating proximity. The substitute parts 170M4565 and 170M4566 maintain the same manufacturer source, voltage class, and holder-dependent mounting architecture. Both substitutes are classified as active products with current availability, addressing the obsolescence of the original part. Current ratings of 550A and 630A respectively provide operational alternatives within the electrical system design envelope. All parts share identical HTSUS and ECCN classifications, confirming regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

Selection between 170M4565 and 170M4566 depends on system current requirements and voltage tolerance specifications. The 170M4566 provides the closest current rating match at 630A, operating at 690V, and is designated as fast-blow response. The 170M4565 operates at 550A with 700VAC rating and includes indicating features with CSA and UR approvals. Both parts are active products with confirmed inventory availability and RoHS compliance status. The choice between these substitutes must align with the specific electrical load parameters and protection coordination requirements of the application circuit.

Frequently Asked Questions (FAQ)

Q: Why is the SPP-5M600 being replaced? A: The SPP-5M600 is classified as obsolete. Active substitute parts from the same manufacturer ensure continued availability and system support.

Q: Are the substitute parts mechanically compatible with existing holders? A: Both 170M4565 and 170M4566 require holder-based mounting, consistent with the original SPP-5M600 design. Physical dimensions for 170M4565 and 170M4566 are 1.969" L x 2.087" W x 2.717" H (50.00mm x 53.00mm x 69.00mm). Holder compatibility must be confirmed against specific installation requirements.

Q: What is the current rating difference between substitutes? A: The 170M4565 is rated at 550A, while the 170M4566 is rated at 630A. The original SPP-5M600 is rated at 600A. Selection depends on circuit protection requirements and load specifications.

Q: Do the substitute parts meet the same regulatory standards? A: All parts share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications. The 170M4565 and 170M4566 are RoHS compliant and carry CSA/UR approvals where applicable.

Q: What is the voltage compatibility range? A: The SPP-5M600 operates at 700V. The 170M4565 is rated for 700VAC, and the 170M4566 is rated for 690V. Both operate within compatible voltage classes for typical industrial applications.
