SPP-6F550 Equivalent & Substitute Parts

Part Overview

The SPP-6F550 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 550A at 700V. This component is part of the Semitron™ SPP series and requires a dedicated holder for installation. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-6F550 is based on the following critical parameters:

• Current Rating: 550A nominal capacity
• Voltage Rating: 700V minimum operating voltage
• Manufacturer Consistency: Eaton - Bussmann Electrical Division maintains electrical and mechanical compatibility within their product lines
• HTSUS Classification: 8536.10.0040 confirms functional category alignment
• Mounting Compatibility: Physical installation method must accommodate existing system infrastructure

The substitute part 170M5711 meets these criteria with equivalent current and voltage ratings, identical manufacturer origin, and matching tariff classification. The transition from holder-mounted to bolt-mount configuration represents a mechanical interface change that must be evaluated against installation requirements.

Parameter Comparison

Engineering Selection Recommendations

The 170M5711 is an active product from the same manufacturer with matching current capacity (550A) and equivalent voltage rating (690V vs. 700V). Both components share identical export classification (EAR99) and tariff codes, confirming functional equivalence within the fuse category.

The primary consideration for selection is the mounting interface change from holder-mount to bolt-mount configuration. This mechanical difference requires verification that the installation environment can accommodate the square bolt-mount form factor and associated installation hardware.

The 170M5711 carries RoHS Compliant status, providing additional environmental compliance assurance compared to the obsolete SPP-6F550.

Frequently Asked Questions (FAQ)

Q: Can the 170M5711 directly replace the SPP-6F550 in existing installations?

A: Both components meet the electrical requirements (550A, 690V/700V). However, the mounting interface differs: SPP-6F550 requires a dedicated holder, while 170M5711 uses bolt-mount configuration. Physical installation compatibility must be confirmed before substitution.

Q: What is the voltage difference between 700V and 690V ratings?

A: The 690V rating of the 170M5711 is within the operating envelope of the 700V SPP-6F550. Both ratings are standard for industrial three-phase systems. The lower rating does not compromise performance in 700V applications.

Q: Does the "Fast Blow" response time of the 170M5711 affect compatibility?

A: Response time characteristics are determined by the fuse element design. The Fast Blow specification of the 170M5711 indicates its protective response profile. Compatibility depends on whether the circuit protection scheme requires this response characteristic.

Q: What does RoHS Compliant status mean for the 170M5711?

A: RoHS Compliance indicates the component meets Restriction of Hazardous Substances requirements, restricting lead, cadmium, mercury, and other regulated materials. This provides environmental and regulatory assurance for new installations.

Q: Are both components from the same manufacturer?

A: Yes. Both SPP-6F550 and 170M5711 are manufactured by Eaton - Bussmann Electrical Division, ensuring consistent electrical performance and quality standards.
