SPP-5H300 Equivalent & Substitute Parts

Part Overview

The SPP-5H300 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 300A at 700V with blade mounting. This component is classified as obsolete, requiring identification of functionally equivalent alternatives for continued system support and procurement planning. Substitute parts must maintain electrical compatibility within the specified voltage and current parameters while accommodating available mounting configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPP-5H300 is determined by the following critical parameters:

• Voltage Rating: Substitute must support minimum 700V AC operation
• Current Rating: Substitute must support 300A nominal current capacity
• Manufacturer Compatibility: Parts from Eaton - Bussmann Electrical Division ensure design and certification alignment
• Mounting Configuration: Substitute mounting type must be compatible with existing system infrastructure

The part 170M4760 meets these substitution criteria as an active product from the same manufacturer with equivalent voltage and current ratings, though with a different mounting configuration (bolt mount versus holder-based mounting).

Parameter Comparison

Engineering Selection Recommendations

The 170M4760 is an active product from the same manufacturer with equivalent voltage rating (700 VAC) and comparable current capacity (315A versus 300A). Both components share identical ECCN and HTSUS classifications, confirming regulatory alignment.

Key considerations for selection:

• Product Status: The 170M4760 is active and currently in production, ensuring long-term availability and supply chain stability
• Compliance: Both parts carry identical export control and tariff classifications
• Certifications: The 170M4760 holds CE, CSA, and UR approvals
• Mounting Compatibility: The transition from holder-based to bolt mount configuration requires mechanical integration assessment within the target application

Frequently Asked Questions (FAQ)

Q: Can the 170M4760 directly replace the SPP-5H300?

A: Both components meet the core electrical requirements (300A/315A at 700V). However, the mounting configuration differs: SPP-5H300 uses a holder-based system while 170M4760 requires bolt mounting. System compatibility depends on the mechanical infrastructure of the application.

Q: What is the significance of the current rating difference (300A vs. 315A)?

A: The 170M4760 has a higher current rating (315A) than the SPP-5H300 (300A). This provides additional capacity margin and does not prevent substitution for 300A applications.

Q: Are there compliance or certification concerns with this substitution?

A: Both components share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications. The 170M4760 carries CE, CSA, and UR approvals, confirming regulatory compliance for industrial and electrical applications.

Q: Why is the SPP-5H300 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 170M4760, as an active product, provides continuity for procurement and system maintenance.

Q: What is the breaking capacity specification?

A: The 170M4760 specifies a breaking capacity of 200kA at rated voltage. This parameter was not provided for the SPP-5H300 in the available documentation.
