KLPC3000X Equivalent & Substitute Parts

Part Overview

The KLPC3000X is a 3kA 600 VAC/480 VDC fuse cartridge manufactured by Littelfuse Inc. under the POWR-GARD® and POWR-PRO® KLPC series. This slow-blow cartridge fuse features bolt mount terminals and is designed for electrical and industrial applications requiring Class L protection. The part maintains active product status with 940 units in current inventory. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, enabling component interchangeability in systems where the original part becomes unavailable or when design specifications permit alternative qualified sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KLPC3000X is determined by the following critical parameters:

• Current Rating: Must be 3kA
• AC Voltage Rating: Must be 600 VAC minimum
• Fuse Type: Must be Cartridge with Slow Blow response
• Mounting Configuration: Must be Bolt Mount with Cylindrical, Blade Terminal design
• Class Rating: Must be Class L
• Approval Certifications: Must maintain CE, CSA, and UL compliance

The KRP-C-3000SP from Eaton - Bussmann Electrical Division satisfies these core substitution criteria. While the DC voltage rating differs (300 VDC versus 480 VDC), this parameter does not prevent substitution in applications where the system operates at or below 300 VDC. The breaking capacity specifications also differ, which must be evaluated against specific circuit protection requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the KLPC3000X and KRP-C-3000SP maintain active product status and carry identical approval certifications (CE, CSA, UL), confirming compliance with applicable electrical safety standards. Selection between these parts depends on system voltage requirements and breaking capacity specifications.

The KLPC3000X is specified for applications requiring 480 VDC operation with 300kA DC breaking capacity. The KRP-C-3000SP is suitable for systems operating at 300 VDC or lower with 100kA DC breaking capacity. Both parts support 600 VAC operation with equivalent or superior AC breaking capacity.

Physical dimensions differ slightly in length (4.000" versus 3.750"), which may affect mounting clearance in confined spaces. Both maintain identical diameter specifications and bolt mount terminal configuration, ensuring mechanical compatibility in standard cartridge fuse holders.

Frequently Asked Questions (FAQ)

Q: Can KRP-C-3000SP replace KLPC3000X in all applications?

A: Substitution is valid only when the system DC voltage does not exceed 300 VDC and the circuit breaking capacity requirement does not exceed 100kA DC. AC applications at 600 VAC are fully compatible. Verify system voltage specifications before substitution.

Q: What is the significance of the Class L rating?

A: Class L cartridge fuses are designed for industrial power distribution circuits. Both parts carry Class L certification, confirming they meet the same performance and safety standards for this application category.

Q: Do the physical dimension differences affect installation?

A: Both parts feature identical 5.000" diameter and bolt mount terminal configuration. The 0.250" length difference (4.000" versus 3.750") may affect clearance in tight mounting spaces. Verify available space in the fuse holder before substitution.

Q: Are both parts RoHS compliant?

A: Yes. The KLPC3000X is ROHS3 Compliant, and the KRP-C-3000SP is RoHS Compliant. Both meet environmental compliance requirements for electronic component manufacturing.

Q: What is the difference in breaking capacity between these parts?

A: The KLPC3000X provides 200kA AC and 300kA DC breaking capacity. The KRP-C-3000SP provides 300kA AC and 100kA DC breaking capacity. Select based on the maximum fault current expected in your circuit.
