Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-4B80 is based on the following critical electrical and mechanical parameters:

• Current Rating: 80A (exact match required)
• Voltage Rating: 700V AC (exact match required)
• Manufacturer: Eaton - Bussmann Electrical Division (same manufacturer ensures design compatibility)
• Mounting compatibility: The substitute must accommodate the electrical circuit requirements and physical installation constraints

The identified substitute, 170M3611, maintains the same current and voltage ratings from the same manufacturer. While the mounting type differs (bolt mount versus blade holder requirement), both parts are classified within the same HTSUS code (8536.10.0040) and serve equivalent protective functions in 80A 700V circuits.

Parameter Comparison

Engineering Selection Recommendations

The 170M3611 is the active equivalent for the obsolete SPP-4B80, maintaining identical electrical protection characteristics at 80A 700V. Both parts originate from Eaton - Bussmann Electrical Division, ensuring design and performance consistency.

The 170M3611 offers additional advantages for new installations and system upgrades: active product status ensures ongoing availability and support, RoHS compliance meets current environmental standards, and multi-agency certifications (CE, CSA, UR) provide broader regulatory acceptance. The specified breaking capacity of 200kA and melting I²t of 185 define the protective performance envelope.

Selection between these parts depends on the existing mounting infrastructure. The SPP-4B80 requires a dedicated blade holder, while the 170M3611 uses bolt mount configuration. Mechanical integration requirements must be evaluated against the electrical circuit design.

Frequently Asked Questions (FAQ)

Q: Can the 170M3611 directly replace the SPP-4B80 in existing installations?

A: Both parts provide identical electrical protection at 80A 700V. However, the mounting type differs: SPP-4B80 requires a blade holder, while 170M3611 uses bolt mount. Physical installation compatibility must be verified against the existing holder or mounting structure.

Q: What are the key electrical parameters that define substitution eligibility?

A: Current rating (80A) and voltage rating (700V) are the primary electrical parameters. Both the SPP-4B80 and 170M3611 meet these specifications. The 170M3611 additionally specifies 200kA breaking capacity and 185 melting I²t.

Q: Why is the SPP-4B80 classified as obsolete?

A: Product status reflects manufacturer lifecycle decisions. The 170M3611 remains active and available, making it the recommended choice for new designs and system replacements.

Q: Are there compliance differences between these parts?

A: The 170M3611 carries CE, CSA, and UR certifications and is RoHS compliant. The SPP-4B80 is REACH unaffected. For applications requiring specific regulatory compliance, the 170M3611 certifications should be verified against system requirements.

Q: What is the inventory status for these parts?

A: SPP-4B80 has 882 pieces in stock (obsolete status). 170M3611 has 1006 pieces in stock (active status), providing better long-term availability assurance.
