0LKS600.Z Equivalent & Substitute Parts

Part Overview

The 0LKS600.Z is a 600A, 600 VAC cylindrical fuse link from Littelfuse's POWR-GARD® LKS series, designed for high-current electrical and industrial applications. This component requires a dedicated holder for installation and operates as a fast-blow fuse with a 10kA breaking capacity at rated voltage. The part is currently obsolete, making identification of compatible substitute components essential for system maintenance and replacement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0LKS600.Z is determined by the following critical parameters:

• Current Rating: 600A
• Voltage Rating: 600 VAC
• Fuse Type: Fuse Link
• Response Time: Fast Blow
• Class: H
• Breaking Capacity: 10kA minimum
• Package Configuration: Cylindrical with blade terminals
• Physical Dimensions: 3.094" Dia x 8.870" L

The substitute part LKS-600 from Eaton - Bussmann Electrical Division meets these electrical and mechanical specifications, enabling direct functional replacement in applications requiring 600A, 600 VAC fuse protection.

Parameter Comparison

Engineering Selection Recommendations

The LKS-600 from Eaton - Bussmann Electrical Division is the designated substitute for the obsolete 0LKS600.Z. Both components share identical electrical ratings (600A, 600 VAC), fuse class (H), response characteristics (fast blow), and physical dimensions. The LKS-600 maintains active product status, ensuring availability for procurement and replacement applications.

The primary distinction is RoHS compliance: the original 0LKS600.Z is RoHS non-compliant, while the LKS-600 is RoHS compliant. This difference may be relevant for applications subject to RoHS regulations. Both components carry equivalent HTSUS classification (8536.10.0040) and ECCN designation (EAR99).

Frequently Asked Questions (FAQ)

Q: Can the LKS-600 be used as a direct replacement for the 0LKS600.Z?

A: Yes. Both components are 600A, 600 VAC fuse links with identical fast-blow response, Class H rating, 10kA breaking capacity, and cylindrical blade terminal configuration. Physical dimensions and mounting requirements are identical.

Q: What is the significance of the RoHS compliance difference?

A: The 0LKS600.Z is RoHS non-compliant, while the LKS-600 is RoHS compliant. For applications in jurisdictions or industries requiring RoHS compliance, the LKS-600 is the appropriate selection.

Q: Are there any compatibility concerns with existing fuse holders?

A: No. Both the 0LKS600.Z and LKS-600 require dedicated fuse holders and share identical cylindrical dimensions (3.094" Dia x 8.870" L). Existing holders designed for the 0LKS600.Z will accommodate the LKS-600 without modification.

Q: Why is the 0LKS600.Z listed as obsolete?

A: Littelfuse has discontinued this part number. The LKS-600 from Eaton - Bussmann serves as the active equivalent for new designs and replacement applications.

Q: What electrical standards apply to these fuse links?

A: Both components carry CE, CSA, and UL approvals (0LKS600.Z specified; LKS-600 approval details not provided in available data). Verification of specific certification requirements for your application is recommended through manufacturer documentation.
