Equivalent & Substitute Parts for 0LKS110.V

Part Overview

The 0LKS110.V is a 110A 600VAC cylindrical fuse link manufactured by Littelfuse Inc. under the POWR-GARD® LKS series. This component is classified as obsolete, requiring identification of active equivalent parts for continued system support and procurement.

The necessity to identify substitute parts stems from the obsolete product status, which limits availability and future supply chain reliability. Active equivalent parts ensure uninterrupted access to compatible components meeting the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0LKS110.V is determined by the following critical parameters:

• Current Rating: 110A (exact match required)
• Voltage Rating (AC): 600 VAC (exact match required)
• Response Time: Fast Blow (functional equivalence)
• Mounting Type: Requires Holder (mechanical compatibility)
• Package / Case: Cylindrical, Blade Terminals (physical compatibility)
• Approval Agencies: CE, CSA, UL (regulatory compliance)

The substitute part KLSR110.X meets all mandatory electrical parameters and maintains mechanical compatibility through identical cylindrical blade terminal configuration. Both parts are rated for 110A at 600 VAC with fast-blow response characteristics and holder-based mounting.

Parameter Comparison

Engineering Selection Recommendations

The KLSR110.X is the manufacturer-recommended substitute for the obsolete 0LKS110.V. Both components share identical electrical ratings (110A, 600 VAC, Fast Blow) and mechanical compatibility (cylindrical blade terminals, holder-based mounting).

Selection of KLSR110.X provides the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• Identical current and voltage ratings maintain electrical system performance
• ROHS3 compliance meets current environmental regulatory requirements
• Enhanced breaking capacity (200kA AC versus 10kA) provides superior fault protection
• Maintained CE, CSA, and UL certifications preserve regulatory compliance

The primary consideration is the dimensional difference: KLSR110.X measures 9.626" length compared to 6.878" for the 0LKS110.V. Verification of holder compatibility and available mounting space is required before implementation.

Frequently Asked Questions (FAQ)

Q: Can KLSR110.X directly replace 0LKS110.V in existing installations?

A: Electrical compatibility is confirmed through matching current rating (110A), voltage rating (600 VAC), and response time (Fast Blow). Mechanical compatibility requires verification that the holder accommodates the longer KLSR110.X length (9.626" versus 6.878").

Q: What is the difference between fuse link and cartridge types?

A: Both are cylindrical fuse types with blade terminals. The primary distinction is form factor and internal construction. The KLSR110.X cartridge design provides higher breaking capacity (200kA AC) compared to the 0LKS110.V fuse link (10kA).

Q: Are the approval certifications equivalent?

A: Both parts carry CE, CSA, and UL certifications. The KLSR110.X additionally meets ROHS3 compliance, reflecting current environmental standards.

Q: What is the significance of the RK1 class rating for KLSR110.X?

A: RK1 classification indicates a current-limiting fuse with enhanced protection characteristics. The H class of 0LKS110.V represents a different fuse classification standard. Both are appropriate for industrial electrical applications at their respective ratings.

Q: Does the additional DC voltage rating of KLSR110.X affect AC-only applications?

A: No. The 300 VDC rating of KLSR110.X is an additional capability that does not impact AC performance. The 600 VAC rating remains the controlling specification for AC circuits.

Q: What holder compatibility must be verified?

A: The cylindrical blade terminal configuration is identical between both parts. The critical verification point is the internal length accommodation within the existing holder, as KLSR110.X is 2.748" longer than 0LKS110.V.
