SPP-6F350 Equivalent & Substitute Parts

Part Overview

The SPP-6F350 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 350A at 700V. This component is classified as obsolete and requires a holder for installation. Due to its obsolete status, identifying equivalent substitute parts is essential for system maintenance, repair, and continued operation in applications where this fuse type is specified.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 170M4711 is identified as an equivalent based on the following critical parameters:

• Current Rating: Both parts are rated for 350A
• Voltage Rating: Both parts are rated for 700V AC
• Manufacturer: Both are manufactured by Eaton - Bussmann Electrical Division
• Regulatory Compliance: Both share the same ECCN (EAR99) and HTSUS code (8536.10.0040)
• Environmental Classification: Both have compatible moisture sensitivity and REACH status

The primary difference lies in the mounting configuration: the SPP-6F350 uses a blade-type fuse link requiring a holder, while the 170M4711 is a square bolt-mount fuse. This distinction requires verification of the installation environment and holder compatibility before substitution.

Parameter Comparison

Engineering Selection Recommendations

The 170M4711 is an active product from the same manufacturer with identical electrical ratings (350A, 700V AC). Its active status and multi-agency certifications (CE, CSA, UR) make it suitable for applications requiring current regulatory compliance. The 170M4711 provides documented breaking capacity (200kA) and melting I²t (8500), parameters not specified for the obsolete SPP-6F350.

Substitution feasibility depends on mechanical compatibility: the SPP-6F350 blade-type fuse link requires a specific holder, while the 170M4711 uses bolt-mount configuration. Installation infrastructure must accommodate the bolt-mount design before substitution is implemented.

Frequently Asked Questions (FAQ)

Q: Can the 170M4711 directly replace the SPP-6F350 in existing installations?

A: Both parts share identical electrical ratings (350A, 700V AC) and are manufactured by Eaton - Bussmann Electrical Division. However, the mounting types differ: SPP-6F350 is a blade-type fuse link requiring a holder, while 170M4711 is a square bolt-mount fuse. Direct replacement requires compatible installation infrastructure.

Q: What are the key electrical parameters for substitution?

A: Current rating (350A) and voltage rating (700V AC) are the primary electrical parameters determining substitution compatibility. Both parts meet these specifications identically.

Q: Why is the SPP-6F350 listed as obsolete?

A: The SPP-6F350 is classified as obsolete by the manufacturer. The 170M4711 is an active equivalent product with the same electrical specifications and enhanced documentation of performance characteristics.

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

A: Both parts share identical ECCN (EAR99) and HTSUS codes (8536.10.0040). The 170M4711 carries multi-agency approvals (CE, CSA, UR) and RoHS compliance, providing enhanced regulatory documentation for modern applications.

Q: What is the significance of the melting I²t and breaking capacity values?

A: The 170M4711 specifies melting I²t (8500) and breaking capacity (200kA at rated voltage). These parameters define thermal and electrical performance characteristics. The SPP-6F350 does not provide these specifications in available documentation.
