Key Parameters

Substitute Part Grouping Explanation

The 170M5612 is identified as a substitute for the SPP-6B600 based on the following electrical and mechanical parameters:

• Voltage Rating: Both components operate at 700V AC
• Manufacturer: Both are manufactured by Eaton - Bussmann Electrical Division
• Current Capacity: The substitute is rated at 630A, providing equivalent or higher current handling capability
• Regulatory Compliance: Both components carry ECCN EAR99 classification and share identical HTSUS coding (8536.10.0040)
• Mounting Configuration: Both are designed for industrial electrical applications requiring high-current fuse protection

The primary distinction lies in the mounting type transition from blade-type holder to bolt mount configuration and the package form factor change from fuse link to rectangular blade.

Parameter Comparison

Engineering Selection Recommendations

The 170M5612 is an active product with current manufacturing support, whereas the SPP-6B600 is obsolete. The substitute maintains electrical compatibility at 700V AC operation and provides equivalent current protection at 630A versus the original 600A rating. The 170M5612 carries multiple international certifications (CE, CSA, UR) and is RoHS compliant, meeting contemporary regulatory requirements. The transition from blade-type to bolt mount configuration requires mechanical integration assessment within the target installation.

Frequently Asked Questions (FAQ)

Q: Can the 170M5612 directly replace the SPP-6B600 in existing installations?

A: Electrical compatibility is established through matching 700V AC voltage ratings and equivalent current capacity. However, the mounting type differs: the SPP-6B600 uses blade-type holder mounting while the 170M5612 requires bolt mount configuration. Physical installation compatibility must be verified against the existing holder or mounting structure.

Q: What is the significance of the current rating difference between 600A and 630A?

A: The 170M5612 is rated at 630A, which exceeds the original 600A specification. This provides equivalent or enhanced protection capability for circuits designed around the 600A threshold.

Q: Are there compliance differences between these components?

A: The 170M5612 carries CE, CSA, and UR certifications and is RoHS compliant. The SPP-6B600 specifications do not document these certifications. Both components share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications.

Q: What does the melting I²t value indicate?

A: The 170M5612 specifies a melting I²t of 41000, which characterizes the thermal energy required to melt the fuse element. This parameter is not provided for the SPP-6B600.

Q: What is the breaking capacity specification?

A: The 170M5612 is rated for 200kA breaking capacity at 700V, indicating the maximum fault current it can safely interrupt. This specification is not documented for the SPP-6B600.
