NON-30 Equivalent & Substitute Parts Reference

Part Overview

The NON-30 is a cartridge fuse manufactured by Eaton - Bussmann Electrical Division, rated for 30A at 250 VAC and 125 VDC. This component is designed for electrical and industrial applications requiring overcurrent protection in circuits with specified voltage and current parameters. The part maintains active product status with 674 units in current inventory.

Substitute parts are identified when electrical and mechanical parameters align within the tolerance specifications for this fuse category, enabling direct replacement in compatible holder assemblies without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

The NON-30 accepts substitutes based on the following critical parameters:

• Current Rating: 30A (exact match required)
• Voltage Rating - AC: 250 VAC (exact match required)
• Fuse Type: Cartridge (exact match required)
• Class: K5 (exact match required)
• Mounting Type: Requires Holder (exact match required)
• Physical Dimensions: Compatible cartridge form factor (0.560" Dia x 2.000" L nominal tolerance)
• Approval Certifications: CE, CSA, UL compliance required

The substitute part 0NLN030.T meets these criteria with the following consideration: DC voltage rating is 250 VDC versus the original 125 VDC specification. This represents an upgrade in DC capability and does not restrict application in circuits designed for 125 VDC operation.

Parameter Comparison

Engineering Selection Recommendations

Both the NON-30 and 0NLN030.T maintain active product status with full regulatory compliance (CE, CSA, UL certifications). Selection between these parts is determined by application requirements:

The NON-30 is specified for circuits with maximum DC voltage of 125 VDC. The 0NLN030.T provides equivalent AC performance with enhanced DC voltage capability (250 VDC). Physical dimensions are nominally compatible within standard cartridge fuse holder tolerances (diameter variance of 0.003" is within typical mechanical clearance specifications).

Both parts carry current RoHS compliance status appropriate for modern industrial and electrical applications. Inventory availability is 674 units for NON-30 and 791 units for 0NLN030.T.

Frequently Asked Questions (FAQ)

Q: Can 0NLN030.T replace NON-30 in all applications?

A: The 0NLN030.T is electrically compatible for circuits designed for NON-30 operation. The higher DC voltage rating (250 VDC vs. 125 VDC) does not restrict use in lower-voltage circuits. Physical dimensions are within standard cartridge fuse holder tolerances.

Q: What is the significance of the K5 fuse class?

A: K5 classification indicates the fuse response characteristics and breaking capacity. Both parts share this classification, ensuring identical protective behavior in the circuit.

Q: Are there dimensional concerns with substitution?

A: Diameter tolerance is 0.560" (NON-30) versus 0.563" (0NLN030.T), a difference of 0.003". Standard cartridge fuse holders accommodate this variance. Length is identical at 2.000".

Q: What is the difference between Fast Blow response and unspecified response time?

A: The 0NLN030.T specifies Fast Blow response. This indicates the fuse opens rapidly under overcurrent conditions. The NON-30 response time is not specified in available documentation. Application requirements for response speed should be confirmed against circuit design specifications.

Q: Do both parts meet current regulatory requirements?

A: Yes. NON-30 is RoHS Compliant; 0NLN030.T is ROHS3 Compliant. Both maintain CE, CSA, and UL certifications. Both are REACH Unaffected and classified as EAR99 for export purposes.
