KRP-C-1350SP Equivalent & Substitute Parts

Part Overview

The KRP-C-1350SP is a 1.35kA cartridge fuse manufactured by Eaton - Bussmann Electrical Division, rated for 600 VAC and 300 VDC operation. This slow-blow fuse cartridge is designed for bolt mount installation in electrical and industrial applications. The part is currently active in production with 649 units in stock. Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and approval certifications align with the original specification, enabling direct replacement in applications where the main part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KRP-C-1350SP is determined by the following critical parameters:

• Current Rating: Must be 1.35kA to ensure proper overcurrent protection coordination
• Voltage Rating - AC: Must be 600 VAC minimum to maintain system voltage compatibility
• Fuse Type & Class: Must be cartridge type, Class L, with slow-blow response characteristics
• Mounting Type: Must be bolt mount to ensure mechanical fit in existing installations
• Physical Dimensions: Must be compatible with 3.000" diameter and approximately 3.750" length to fit standard cartridge holders
• Approval Certifications: Must carry CE, CSA, and UL approvals for regulatory compliance

The KLPC1350X from Littelfuse Inc. meets these substitution criteria. While the DC voltage rating differs (480 VDC versus 300 VDC), this represents an enhanced capability that does not compromise compatibility in applications rated for 300 VDC operation. Physical dimensions remain within acceptable tolerance, and all required certifications are present.

Parameter Comparison

Engineering Selection Recommendations

Both the KRP-C-1350SP and KLPC1350X are active production components with full regulatory approvals (CE, CSA, UL). Selection between these parts should be based on:

KRP-C-1350SP is the original specification part, suitable for applications where the exact Eaton - Bussmann LOW-PEAK™ KRP-C series performance characteristics are required or preferred.

KLPC1350X is a qualified substitute offering equivalent electrical performance with enhanced DC voltage capability (480 VDC versus 300 VDC). This part is suitable for direct replacement in existing installations and provides additional margin for DC applications. The Littelfuse POWR-GARD® and POWR-PRO® series carries equivalent certifications and maintains mechanical compatibility.

Both parts are RoHS compliant and carry the same ECCN and HTSUS classifications, ensuring regulatory and procurement consistency.

Frequently Asked Questions (FAQ)

Q: Can KLPC1350X be used as a direct replacement for KRP-C-1350SP?

A: Yes. Both parts share identical current ratings (1.35kA), AC voltage ratings (600 VAC), fuse class (L), mounting type (bolt mount), response time (slow blow), and physical dimensions within tolerance. All required certifications (CE, CSA, UL) are present on both parts.

Q: Why does KLPC1350X have a higher DC voltage rating (480 VDC vs. 300 VDC)?

A: The higher DC voltage rating on the KLPC1350X represents enhanced capability and does not affect compatibility in applications designed for 300 VDC operation. This provides additional safety margin in DC circuits.

Q: Are the physical dimensions identical?

A: Dimensions are functionally equivalent. KRP-C-1350SP is 3.000" Dia x 3.750" L (76.20mm x 95.25mm), while KLPC1350X is 3.000" Dia x 3.752" L (76.20mm x 95.30mm). The 0.002" length difference is within standard cartridge holder tolerances and does not affect mechanical fit.

Q: Do both parts carry the same regulatory approvals?

A: Yes. Both the KRP-C-1350SP and KLPC1350X carry CE, CSA, and UL approvals, ensuring compliance with the same regulatory standards.

Q: What is the difference in RoHS compliance status?

A: KRP-C-1350SP is RoHS Compliant, while KLPC1350X is ROHS3 Compliant. ROHS3 represents the current RoHS directive standard and indicates the part meets the latest environmental compliance requirements.

Q: Can these parts be used interchangeably in the same circuit?

A: Yes, provided the application voltage and current requirements do not exceed the ratings of either part. Both parts are rated for 1.35kA at 600 VAC and are suitable for electrical and industrial applications requiring Class L slow-blow cartridge fuses with bolt mount installation.
