SPP-5E450 Equivalent & Substitute Parts

Part Overview

The SPP-5E450 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 450A at 700V operation. This component is classified as obsolete and requires a holder for installation. Due to its obsolete status, identifying equivalent substitute parts with matching electrical and mechanical specifications is essential for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SPP-5E450 is determined by the following critical parameters:

• Current Rating: 450A
• Voltage Rating: 700V (AC)
• Manufacturer: Eaton - Bussmann Electrical Division
• Regulatory Compliance: REACH Unaffected, EAR99 classification

The substitute part 170M4663 shares the same current and voltage ratings from the same manufacturer, ensuring electrical compatibility. While the mounting configuration differs (bolt mount versus holder-based), both components operate within the same electrical specifications and are classified under the same HTSUS code, confirming their functional equivalence for 450A/700V applications.

Parameter Comparison

Engineering Selection Recommendations

The 170M4663 is the designated substitute for the obsolete SPP-5E450. Both components are manufactured by Eaton - Bussmann Electrical Division and share identical electrical ratings of 450A at 700V. The substitute part is currently in active production status with 5100 units available in inventory, compared to the obsolete main part with 680 units remaining.

Both parts carry EAR99 classification and are assigned the same HTSUS code (8536.10.0040), confirming their regulatory equivalence. The 170M4663 includes additional technical specifications: a breaking capacity of 200kA at rated voltage and a melting I²t value of 17000.0, providing documented performance characteristics for the substitute component.

The primary difference is the mounting configuration: the SPP-5E450 requires a separate holder, while the 170M4663 uses bolt mount installation. This distinction requires mechanical integration assessment during component replacement but does not affect electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 170M4663 directly replace the SPP-5E450 in existing installations?

A: Both components share identical electrical specifications (450A, 700V) and are from the same manufacturer. However, the mounting method differs: SPP-5E450 requires a holder, while 170M4663 uses bolt mount. Mechanical integration must be evaluated for your specific installation.

Q: What is the significance of the obsolete status of SPP-5E450?

A: Obsolete status indicates the part is no longer manufactured. The 170M4663 is an active production part with current availability, making it the appropriate choice for new procurement and system maintenance.

Q: Are there compliance differences between the two parts?

A: Both parts share the same ECCN (EAR99) and HTSUS code (8536.10.0040). Regulatory compliance is equivalent for export and tariff classification purposes.

Q: What do the breaking capacity and melting I²t specifications indicate?

A: Breaking capacity (200kA) defines the maximum fault current the fuse can safely interrupt at rated voltage. Melting I²t (17000.0) characterizes the thermal energy required to melt the fuse element, determining response time under overcurrent conditions.

Q: Is the 170M4663 RoHS compliant?

A: Yes, the 170M4663 is RoHS compliant. The SPP-5E450 RoHS status is not specified in available documentation.
