All identified substitute parts meet these criteria and are manufactured by Eaton - Bussmann Electrical Division within the SC series.

Parameter Comparison

Engineering Selection Recommendations

All three parts—BP/SC-30, BK/SC-30, and SC-30—are functionally equivalent and maintain Active product status. Selection between these parts may be based on inventory availability and compliance requirements. The SC-30 carries ROHS3 compliance, while BP/SC-30 and BK/SC-30 carry standard RoHS compliance. All parts hold CE, CSA, and UL approvals, confirming suitability for regulated applications. The choice among these equivalents does not affect electrical performance or mechanical compatibility within the specified holder assembly.

Frequently Asked Questions (FAQ)

Q: Can BK/SC-30 and SC-30 be used interchangeably with BP/SC-30?

A: Yes. All three parts share identical electrical ratings (30 A, 480 V AC, 300 V DC), response characteristics (Slow Blow), breaking capacity (100 kA AC, 10 kA DC), physical dimensions (0.410" Dia x 1.620" L), and approval certifications (CE, CSA, UL). They are mechanically and electrically interchangeable.

Q: What is the difference between BP/SC-30, BK/SC-30, and SC-30?

A: The primary difference is RoHS compliance designation. SC-30 is ROHS3 compliant, while BP/SC-30 and BK/SC-30 are RoHS compliant. All other electrical, mechanical, and regulatory parameters are identical.

Q: Do these fuses require a specific holder?

A: Yes. All three parts are cartridge fuses requiring a dedicated holder for installation. The non-standard cartridge format necessitates a compatible SC series holder assembly.

Q: Are these parts suitable for both AC and DC applications?

A: Yes. Each part is rated for 480 V AC and 300 V DC, supporting dual-voltage applications within these specifications.

Q: What certifications do these parts carry?

A: All three parts hold CE, CSA, and UL approvals, confirming compliance with international safety and performance standards.
