SPP-7B1000 Equivalent & Substitute Parts

Part Overview

The SPP-7B1000 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 1kA at 700V with blade mounting. This component is classified as obsolete, requiring identification of active equivalent parts for continued system support and procurement. The obsolete status necessitates sourcing alternative components that maintain electrical and mechanical compatibility with existing installations.

Key Parameters

Substitute Part Grouping Explanation

The 170M6614 serves as a functional equivalent to the SPP-7B1000 based on the following critical parameters:

• Current Rating: Both components are rated for 1kA
• Voltage Rating: Both operate at 700V AC
• Manufacturer: Both are manufactured by Eaton - Bussmann Electrical Division
• Electrical Classification: Both are fuses within the same voltage and current class
• Compliance: The 170M6614 holds active product status with CE, CSA, and UR approvals

The primary difference lies in mounting configuration: the SPP-7B1000 requires a separate holder, while the 170M6614 features bolt mount capability. This distinction affects installation methodology but does not alter the core electrical protection function.

Parameter Comparison

Engineering Selection Recommendations

The 170M6614 is the designated substitute for the obsolete SPP-7B1000. Selection is based on:

• Electrical Equivalence: Identical current and voltage ratings ensure protection characteristics remain unchanged
• Active Product Status: The 170M6614 maintains active manufacturing status with current regulatory compliance
• Certification Coverage: CE, CSA, and UR approvals provide broad industrial and regional acceptance
• Manufacturer Continuity: Both components originate from Eaton - Bussmann Electrical Division, ensuring design consistency and supply chain reliability

Installation requires evaluation of the mounting interface. The transition from holder-based mounting to bolt mount configuration necessitates mechanical adaptation within the host equipment.

Frequently Asked Questions (FAQ)

Q: Can the 170M6614 directly replace the SPP-7B1000 without modification?

A: Electrical replacement is direct due to matching current and voltage ratings. Mechanical installation requires assessment of the existing holder or mounting structure, as the 170M6614 uses bolt mount configuration rather than requiring a separate holder.

Q: What is the significance of the 1kA current rating and 700V voltage rating in substitution?

A: These parameters define the fuse's protective function. Both components share identical ratings, ensuring equivalent fault protection and circuit behavior. Substitution outside these parameters would alter system protection characteristics.

Q: Why is the SPP-7B1000 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 170M6614 represents the active equivalent within Eaton - Bussmann's current product portfolio.

Q: What does the 200kA breaking capacity of the 170M6614 indicate?

A: Breaking capacity specifies the maximum fault current the fuse can safely interrupt at rated voltage. This parameter is provided for the 170M6614 but not documented for the obsolete SPP-7B1000.

Q: Are there compliance differences between these components?

A: The 170M6614 carries CE, CSA, and UR certifications and is RoHS compliant. The SPP-7B1000, being obsolete, reflects historical compliance standards. Both share REACH Unaffected or equivalent status.
