Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-5E400 is determined by electrical and mechanical compatibility across the following parameters:

• Current Rating: 400A (exact match required)
• Voltage Rating: 700V AC (exact match required)
• Manufacturer: Eaton - Bussmann Electrical Division (same manufacturer ensures design compatibility)
• Mounting compatibility: Blade or bolt mount configurations that accommodate 400A/700V operation
• Regulatory compliance: REACH and ECCN classifications must align with the original specification

The substitute part 170M4662 satisfies these criteria as an active product with identical electrical ratings and equivalent mechanical form factor suitable for 400A/700V applications.

Parameter Comparison

Engineering Selection Recommendations

The 170M4662 serves as the active equivalent for the obsolete SPP-5E400 based on matching electrical specifications (400A, 700 VAC) and manufacturer continuity within the Eaton - Bussmann product line. Both parts share identical ECCN classification (EAR99), ensuring regulatory alignment.

The 170M4662 is currently in active production status with documented inventory availability, providing supply chain continuity for applications requiring 400A/700V fuse protection. The part carries RoHS compliance certification and demonstrates a breaking capacity of 200kA at rated voltage, supporting industrial and electrical applications.

Mechanical integration requires verification of mounting interface compatibility, as the SPP-5E400 utilizes blade-mount holder configuration while the 170M4662 employs bolt-mount design. System integration must account for this dimensional and mechanical difference during component selection.

Frequently Asked Questions (FAQ)

Q: Can the 170M4662 directly replace the SPP-5E400 in existing installations?

A: Electrical compatibility is confirmed through matching 400A/700V ratings. Mechanical compatibility depends on the mounting infrastructure. The SPP-5E400 requires a blade-mount holder, while the 170M4662 uses bolt-mount configuration. Installation feasibility requires assessment of the existing mounting structure.

Q: What are the key parameters that determine substitution eligibility?

A: Current rating (400A), voltage rating (700V AC), and manufacturer (Eaton - Bussmann Electrical Division) are the primary substitution criteria. Secondary considerations include breaking capacity (200kA for 170M4662), melting I²t value (13500), and regulatory compliance (ECCN EAR99, RoHS status).

Q: Why is the SPP-5E400 listed as obsolete?

A: The SPP-5E400 has been discontinued by the manufacturer. The 170M4662 represents the active product line continuation for equivalent 400A/700V fuse applications within the Eaton - Bussmann portfolio.

Q: Are there compliance differences between the two parts?

A: Both parts share EAR99 ECCN classification. The 170M4662 carries RoHS compliance certification. REACH status for the 170M4662 is not specified in available documentation.

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

A: The 200kA breaking capacity of the 170M4662 indicates the maximum fault current the fuse can safely interrupt at rated voltage (700 VAC). This specification is critical for system protection design and must be verified against circuit requirements.
