Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-7E700 is determined by the following critical electrical and mechanical parameters:

• Current Rating: 700A (exact match required)
• Voltage Rating: 700V AC (exact match required)
• Manufacturer: Eaton - Bussmann Electrical Division (same manufacturer ensures design compatibility)
• Mounting compatibility: Substitute must accommodate the electrical distribution system's installation requirements

The substitute part 170M6661 meets these core criteria while offering an active product status, ensuring continued availability and support for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The 170M6661 serves as the primary substitute for the obsolete SPP-7E700 based on electrical equivalence: both components share identical current (700A) and voltage (700 VAC) ratings from the same manufacturer. The 170M6661 holds active product status, ensuring supply chain continuity and technical support availability.

Key compliance considerations: Both parts carry EAR99 ECCN classification and share the same HTSUS code (8536.10.0040), confirming regulatory alignment. The 170M6661 provides additional RoHS compliance certification, meeting modern environmental standards.

Mechanical differences exist: the SPP-7E700 uses a blade-type fuse link requiring a holder, while the 170M6661 employs a square bolt-mount configuration. System integration requires verification that the installation environment accommodates the bolt-mount design of the substitute component.

Frequently Asked Questions (FAQ)

Q: Can the 170M6661 directly replace the SPP-7E700 in all applications?

A: Both components meet identical electrical specifications (700A, 700V). However, the mounting configuration differs: SPP-7E700 requires a holder, while 170M6661 uses bolt-mount. Installation compatibility depends on the existing electrical distribution system's mechanical design.

Q: What is the significance of the SPP-7E700 being obsolete?

A: Obsolete status indicates the manufacturer no longer produces this component. The 170M6661, classified as active, ensures ongoing availability for future replacement needs and technical support from Eaton - Bussmann Electrical Division.

Q: Are there compliance differences between these parts?

A: Both components share EAR99 ECCN and 8536.10.0040 HTSUS classification. The 170M6661 provides RoHS compliance certification, meeting current environmental regulations. The SPP-7E700 carries REACH Unaffected status.

Q: What do the electrical parameters (Breaking Capacity and Melting I²t) indicate?

A: The 170M6661 specifies 200kA breaking capacity and 44500.0 melting I²t. These parameters define the fuse's performance under fault conditions. The SPP-7E700 specifications for these parameters were not provided in available documentation.

Q: How should mounting type differences be evaluated?

A: The SPP-7E700 blade-type design requires a compatible holder assembly. The 170M6661 bolt-mount design integrates directly into systems with bolt-mount infrastructure. System design review is necessary to confirm mechanical compatibility before substitution.
