BP/NON-30 Equivalent & Substitute Parts

Part Overview

The BP/NON-30 is a 30A cartridge fuse rated for 250 VAC and 125 VDC operation, manufactured by Eaton - Bussmann Electrical Division. This component is classified as discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing system maintenance and new designs. The part requires a compatible fuse holder for installation and is approved for electrical and industrial applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BP/NON-30 is determined by the following critical parameters:

• Current Rating: 30A (exact match required)
• Voltage Rating - AC: 250 VAC (exact match required)
• Voltage Rating - DC: Minimum 125 VDC (equal or higher acceptable)
• Fuse Type: Cartridge (exact match required)
• Class: K5 (exact match required)
• Package / Case: Cartridge, Non-Standard (physical compatibility required)
• Size / Dimension: 0.560" Dia x 2.000" L nominal (minor tolerance variations acceptable)
• Approval Agency: CE, CSA, UL certifications (required for equivalent functionality)

The substitute part 0NLN030.T meets these criteria with equivalent electrical ratings and certifications, with the exception of DC voltage rating which is rated higher (250 VDC vs. 125 VDC), providing enhanced capability in DC applications.

Parameter Comparison

Engineering Selection Recommendations

The 0NLN030.T (Littelfuse POWR-GARD® NLN series) is the direct equivalent substitute for the BP/NON-30. Both components share identical current ratings (30A), AC voltage ratings (250 VAC), fuse class (K5), and regulatory approvals (CE, CSA, UL). The 0NLN030.T provides enhanced DC voltage capability (250 VDC vs. 125 VDC), making it suitable for applications requiring the original BP/NON-30 specifications or higher DC voltage tolerance.

Physical dimensions are nominally equivalent (0.560" vs. 0.563" diameter), with both cartridges measuring 2.000" in length. Both components require compatible fuse holders and are RoHS compliant. The 0NLN030.T is currently in active production status, ensuring availability for replacement and new system designs.

Frequently Asked Questions (FAQ)

Q: Can the 0NLN030.T replace the BP/NON-30 in existing systems?

A: Yes. Both components are 30A, 250 VAC cartridge fuses with K5 class ratings and identical regulatory approvals. The 0NLN030.T is physically compatible with standard cartridge fuse holders designed for the BP/NON-30 form factor.

Q: What is the significance of the higher DC voltage rating on the 0NLN030.T?

A: The 0NLN030.T is rated for 250 VDC compared to the BP/NON-30's 125 VDC rating. This provides additional margin in DC applications and does not restrict use in circuits designed for 125 VDC operation.

Q: Are there dimensional compatibility concerns?

A: Diameter tolerance is minimal (0.560" vs. 0.563"), and both cartridges are 2.000" in length. Standard cartridge fuse holders accommodate this variation. Physical fit should be verified with the specific holder model in use.

Q: Do both parts carry the same regulatory certifications?

A: Yes. Both the BP/NON-30 and 0NLN030.T carry CE, CSA, and UL approvals, meeting equivalent regulatory requirements for electrical and industrial applications.

Q: Why is the BP/NON-30 discontinued?

A: Product discontinuation is a manufacturing decision by Eaton - Bussmann. The 0NLN030.T provides equivalent functionality and is actively manufactured by Littelfuse.
