SPP-6F500 Equivalent & Substitute Parts

Part Overview

The SPP-6F500 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 500A at 700V operation. 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 operational support where original inventory is depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 170M5710 shares the critical electrical parameters with the SPP-6F500: both are rated for 500A current capacity and are manufactured by Eaton - Bussmann Electrical Division. The substitution is based on matching current rating (500A), manufacturer consistency, and compliance certifications (REACH Unaffected / RoHS Compliant). The 170M5710 operates at 70 VAC, which differs from the original 700V specification; however, this part is listed as an active substitute in the provided data and maintains the same HTSUS classification (8536.10.0040), indicating functional equivalence within the fuse link category for industrial electrical applications.

Parameter Comparison

Engineering Selection Recommendations

The 170M5710 is the designated substitute for the obsolete SPP-6F500 based on current rating equivalence (500A) and manufacturer consistency. The 170M5710 carries active product status with CE, CSA, and UR certifications, providing regulatory compliance for industrial electrical applications. The transition from holder-mount to bolt-mount configuration requires mechanical integration review in the target application. The voltage specification difference (700V to 70 VAC) must be evaluated against the actual operating voltage of the intended circuit to ensure compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 170M5710 directly replace the SPP-6F500 in all applications? A: Both parts share the same 500A current rating and manufacturer. However, the mounting type differs (holder-mount vs. bolt-mount), and the voltage rating changes from 700V to 70 VAC. Mechanical integration and circuit voltage must be verified before substitution.

Q: What is the significance of the current rating match? A: The 500A current rating is the primary electrical parameter determining fuse substitution eligibility. Both parts are rated identically at this level, establishing functional equivalence for overcurrent protection in this amperage class.

Q: Why is the 170M5710 listed as active while the SPP-6F500 is obsolete? A: The 170M5710 remains in active production by Eaton - Bussmann Electrical Division, making it the recommended source for new procurement. The SPP-6F500 has been discontinued and is no longer manufactured.

Q: What do the certifications (CE, CSA, UR) indicate for the 170M5710? A: These certifications confirm compliance with European (CE), Canadian/US (CSA), and Underwriters Laboratories (UR) safety standards, ensuring the part meets regulatory requirements for industrial electrical equipment in multiple markets.

Q: How do the melting I²t and breaking capacity specifications affect selection? A: The 170M5710 specifies a melting I²t of 21500 and breaking capacity of 200kA at rated voltage. These parameters define the fuse's thermal and electrical performance characteristics. The SPP-6F500 specifications are not provided in the available data, making direct thermal comparison impossible.
