Key Parameters

Substitute Part Grouping Explanation

Substitution for the 40C14X51GI/I is determined by the following critical parameters:

• Current Rating: 40A
• Voltage Rating: 500VAC
• Product Type: Fuse Cartridge
• Mechanical Compatibility: Requires Holder

The identified substitute part maintains identical electrical specifications (40A, 500VAC) and the same mechanical requirement for a dedicated holder. Substitution is valid when all four parameters match the original part.

Parameter Comparison

Engineering Selection Recommendations

Both the 40C14X51GI/I and 40C14X51GI are manufactured by Altech Corporation with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and procurement lead times. Both parts are new original stock and suitable for direct substitution in applications requiring a 40A, 500VAC fuse cartridge with holder mounting.

Frequently Asked Questions (FAQ)

Q: Can the 40C14X51GI substitute for the 40C14X51GI/I? A: Yes. Both parts share identical current rating (40A), voltage rating (500VAC), product type (fuse cartridge), and holder requirement. They are direct substitutes.

Q: What determines compatibility between these fuse cartridges? A: Compatibility is determined by matching current rating, voltage rating, product type, and mechanical holder compatibility. All four parameters must align for substitution.

Q: Are there any packaging differences between these parts? A: Packaging information is not provided in the technical specifications for either part. Consult the manufacturer for packaging details if required for your application.

Q: Can these parts be used interchangeably in existing installations? A: Yes, provided the existing installation uses a compatible fuse holder designed for 40A, 500VAC cartridge fuses. The mechanical and electrical specifications are identical.
