• Active Product Status: The 170M4666 is classified as Active, ensuring ongoing availability and support

Parameter Comparison

Engineering Selection Recommendations

The 170M4666 is the designated substitute for SPP-5E600 applications. Selection is based on:

• Regulatory Compliance: Both components share identical export control and tariff classifications, ensuring no compliance barriers to substitution
• Active Product Availability: The 170M4666 maintains active product status with documented inventory (992 Pcs), providing reliable procurement continuity
• Certification Coverage: The substitute carries CE, CSA, and UR approvals, supporting deployment in regulated industrial and electrical applications
• Electrical Equivalence: Matching voltage rating (700V) and comparable current rating (630A vs. 600A) establish functional compatibility

Frequently Asked Questions (FAQ)

Q: Can the 170M4666 directly replace the SPP-5E600 in existing installations?

A: The 170M4666 provides electrical equivalence at matching voltage (700V) and comparable current rating (630A). However, mounting type differs: SPP-5E600 requires a holder, while 170M4666 uses bolt mount. Physical installation compatibility must be verified against the specific holder or mounting assembly in use.

Q: What is the significance of the current rating difference (600A vs. 630A)?

A: The 170M4666 at 630A exceeds the SPP-5E600 specification of 600A. This higher rating provides operational margin and is acceptable for applications designed for 600A operation, as the substitute will not trip at lower thresholds than the original component.

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

A: The 170M4666 carries CE, CSA, and UR certifications. Both components share identical ECCN and HTSUS classifications. The substitute's additional certifications support broader regulatory acceptance in industrial applications.

Q: Why is the SPP-5E600 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 170M4666 represents the active equivalent within Eaton - Bussmann's current product portfolio, ensuring continued support and availability.

Q: What are the physical dimension implications of substitution?

A: The 170M4666 dimensions are 1.969" L x 2.087" W x 2.717" H (50.00mm x 53.00mm x 69.00mm). Verification against the original installation space is required to confirm fit within existing enclosures or mounting assemblies.
