SPP-4E200 Equivalent & Substitute Parts

Part Overview

The SPP-4E200 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 200A at 700V operation. This component is classified as obsolete and requires a holder for installation. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for system maintenance, repair, and component sourcing in applications where this fuse link is currently deployed.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SPP-4E200 is determined by the following critical electrical and mechanical parameters:

• Current Rating: 200A (exact match required)
• Voltage Rating: 700V AC (exact match required)
• Manufacturer: Eaton - Bussmann Electrical Division (same manufacturer ensures design compatibility)
• Mounting Configuration: The main part requires a holder; substitute parts must accommodate the existing installation infrastructure

The substitute part 170M3665 meets these core criteria. While it features a different fuse type (Square vs. Blade) and mounting method (Bolt Mount vs. Requires Holder), it maintains electrical equivalence through identical current and voltage ratings from the same manufacturer. The physical form factor difference requires evaluation of the installation environment to confirm mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 170M3665 is the identified substitute for the obsolete SPP-4E200 based on electrical parameter equivalence (200A, 700V). The substitute part is currently active in production, ensuring availability for replacement applications.

Key considerations for selection:

• Electrical Compatibility: Both parts maintain identical current and voltage ratings, ensuring functional equivalence in circuit protection applications.
• Regulatory Compliance: The 170M3665 carries CSA and UR approvals and is RoHS compliant, providing enhanced compliance documentation compared to the obsolete SPP-4E200.
• Mechanical Integration: The transition from blade-type with holder requirement to square bolt-mount configuration requires assessment of the existing installation framework. Physical dimensions (1.969" L x 1.772" W x 2.323" H) must be evaluated against available mounting space and holder compatibility.
• Availability: The 170M3665 is in active production with current inventory, whereas the SPP-4E200 is obsolete.

Frequently Asked Questions (FAQ)

Q: What makes the 170M3665 an equivalent substitute for the SPP-4E200?

A: Both parts are manufactured by Eaton - Bussmann Electrical Division and share identical electrical specifications: 200A current rating and 700V voltage rating. These parameters are the primary determinants of fuse substitution in electrical protection circuits.

Q: Can the 170M3665 be directly installed in place of the SPP-4E200?

A: Electrical compatibility is confirmed. However, the mounting configuration differs: the SPP-4E200 requires a holder, while the 170M3665 uses bolt mount. The installation environment must accommodate the square fuse type and bolt-mount design before substitution.

Q: What is the significance of the different fuse types (Blade vs. Square)?

A: Fuse type refers to the physical form factor and contact configuration. While both types serve the same electrical protection function at identical ratings, they require different mounting hardware and holders. The specific installation must support the substitute part's form factor.

Q: Are there compliance differences between these parts?

A: The 170M3665 carries CSA and UR approvals and is RoHS compliant. The SPP-4E200 specifications do not document these certifications. For applications requiring specific regulatory compliance, the 170M3665 provides documented approval agency support.

Q: What is the Melting I²t value, and why does it matter?

A: The Melting I²t (2200 for the 170M3665) indicates the thermal energy required to melt the fuse element. This parameter, combined with breaking capacity (200kA), defines the fuse's response characteristics under fault conditions. The SPP-4E200 does not specify this value in available documentation.
