Key Parameters

Substitute Part Grouping Explanation

The substitute part 170M3715 is identified as functionally equivalent based on the following critical parameters:

• Current Rating: Both parts rated at 200A
• Voltage Rating: Both parts rated at 700V AC
• Manufacturer: Both manufactured by Eaton - Bussmann Electrical Division
• Regulatory Compliance: Both classified under HTSUS 8536.10.0040 and ECCN EAR99

The primary difference is the mounting configuration: SPP-4F200 requires a separate holder, while 170M3715 features bolt mount capability. This distinction affects installation methodology but does not alter the electrical protection characteristics or current/voltage ratings.

Parameter Comparison

Engineering Selection Recommendations

The 170M3715 is an active product substitute for the obsolete SPP-4F200. Both components share identical electrical ratings (200A, 700V) and are manufactured by the same supplier. The 170M3715 carries active product status with CSA and UR approvals, providing regulatory assurance for new installations and system upgrades.

The transition from blade-mounted to bolt-mount configuration requires mechanical integration assessment within the target application. The 170M3715 provides documented breaking capacity (200kA) and melting I²t characteristics (2200), enabling precise fault protection analysis.

Frequently Asked Questions (FAQ)

Q: Can 170M3715 directly replace SPP-4F200 in existing installations?

A: Both components provide identical electrical protection at 200A and 700V. However, the mounting configuration differs: SPP-4F200 uses a blade-type holder mount, while 170M3715 requires bolt mounting. Physical installation compatibility must be verified against the existing mounting infrastructure.

Q: What are the key electrical parameters for substitution?

A: Current rating (200A) and voltage rating (700V) are the primary electrical parameters determining substitution eligibility. Both parts meet these specifications identically.

Q: Why is SPP-4F200 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 170M3715 represents the active alternative within the Eaton - Bussmann product portfolio.

Q: Are there regulatory differences between these parts?

A: Both parts are classified under identical HTSUS (8536.10.0040) and ECCN (EAR99) codes. The 170M3715 carries CSA and UR approvals, while SPP-4F200 approval agencies are not specified in available documentation.

Q: What is the significance of the melting I²t value?

A: The melting I²t (2200) for 170M3715 defines the thermal energy required to melt the fuse element, determining response characteristics under fault conditions. This parameter is not specified for SPP-4F200.
