3ABP 6-R Ceramic Fuse Equivalent & Substitute Parts

Part Overview

The 3ABP 6-R is a 6 A 250 V AC ceramic cartridge fuse manufactured by Bel Fuse Inc., designed for through-hole mounting in 3AB/3AG package format. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The fast-blow response characteristic and ceramic construction provide reliable overcurrent protection in industrial and commercial applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3ABP 6-R is determined by strict equivalence across the following critical parameters:

• Current Rating: 6 A (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

All three substitute parts—0324006.HXP, 0324006.MXP, and 0324006.VXP—manufactured by Littelfuse Inc., meet these core electrical and mechanical requirements. These parts are classified as active products with enhanced specifications including DC voltage rating capability (125 V DC) and higher breaking capacity ratings.

Parameter Comparison

Engineering Selection Recommendations

All three Littelfuse substitute parts (0324006.HXP, 0324006.MXP, 0324006.VXP) are functionally equivalent to the 3ABP 6-R for AC 250 V applications. Selection among these three active alternatives should be based on:

• Product availability and inventory status
• Approval agency certifications required for the target application
• DC voltage rating requirement (125 V DC capability in all Littelfuse substitutes provides additional operational flexibility)
• Compliance with ROHS3 and REACH requirements (all substitutes meet these standards)

The Littelfuse substitutes offer enhanced breaking capacity (750 A AC, 10 kA DC) compared to the original 3ABP 6-R (200 A), providing superior fault protection margins. The lower melting I²t value (45 versus 107) indicates faster thermal response, which may require circuit design verification in sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can 0324006.HXP, 0324006.MXP, and 0324006.VXP be used interchangeably with 3ABP 6-R?

A: Yes, for AC 250 V applications. All three Littelfuse parts meet the core electrical and mechanical specifications: 6 A current rating, 250 V AC voltage rating, fast-blow ceramic cartridge construction, and 3AB/3AG package format. Selection among the three should be based on availability and specific approval agency requirements.

Q: What is the difference between 0324006.HXP, 0324006.MXP, and 0324006.VXP?

A: These three parts are electrically and mechanically identical. Differences exist only in approval agency certifications: 0324006.HXP carries CE, CSA, K-MARK, PSE, and UL approvals; 0324006.MXP carries the same certifications; 0324006.VXP carries CE, CSA, KC, PSE, and UL approvals. Selection depends on regional compliance requirements.

Q: Does the lower melting I²t value in Littelfuse substitutes affect compatibility?

A: The Littelfuse substitutes have a melting I²t of 45 compared to 107 in the 3ABP 6-R. This indicates faster thermal response. For direct replacement in existing circuits, this difference should be evaluated against circuit protection requirements and fault current characteristics.

Q: Are the Littelfuse substitutes RoHS and REACH compliant?

A: Yes. All three Littelfuse substitute parts (0324006.HXP, 0324006.MXP, 0324006.VXP) are ROHS3 compliant and REACH unaffected, matching the compliance status of the original 3ABP 6-R.

Q: Can these fuses be used in DC applications?

A: The 3ABP 6-R does not specify a DC voltage rating. The Littelfuse substitutes are rated for 125 V DC, providing DC application capability not documented for the original part. DC application suitability must be determined by circuit requirements and fault current analysis.
