Equivalent & Substitute Parts for 0LKS010.S

Part Overview

The 0LKS010.S is a 10A 600VAC cartridge fuse link manufactured by Littelfuse Inc. under the POWR-GARD® LKS series. This fast-blow fuse is designed for electrical and industrial applications requiring Class H protection with a breaking capacity of 10kA at rated voltage. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 0LKS010.S is determined by the following critical parameters:

• Current Rating: 10A (exact match required)
• Voltage Rating (AC): 600 VAC (exact match required)
• Response Time: Fast Blow (functional equivalence)
• Mounting Type: Requires Holder (mechanical compatibility)
• Approval Certifications: CE, CSA, UL (regulatory compliance)

Two substitute parts meet these core criteria:

1. KLSR010.T (Littelfuse Inc., POWR-GARD® KLSR series) - Active product with enhanced specifications
2. LKS-10 (Eaton - Bussmann Electrical Division) - Active product with RoHS compliance

Both substitutes maintain the 10A current rating and 600 VAC AC voltage requirement. The KLSR010.T provides additional DC voltage capability (250 VDC) and higher breaking capacity (200kA AC, 20kA DC), while the LKS-10 offers RoHS compliance as a renewable link design.

Parameter Comparison

Engineering Selection Recommendations

KLSR010.T is the primary substitute for direct replacement in existing 0LKS010.S applications. Both parts are manufactured by Littelfuse Inc., share identical current and AC voltage ratings, and carry the same regulatory certifications (CE, CSA, UL). The KLSR010.T is an active product with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The increased length (5.000" vs 3.748") must be verified for physical fit within the existing fuse holder assembly.

LKS-10 (Eaton - Bussmann) serves as an alternative substitute with RoHS compliance. This product is active and available. Limited technical specification data is provided for this part; verification of voltage rating, response time, and mechanical compatibility with the original holder is necessary before selection.

Selection between KLSR010.T and LKS-10 depends on holder compatibility, space constraints, and supply chain preferences. KLSR010.T is recommended as the primary choice due to complete specification alignment and same-manufacturer sourcing.

Frequently Asked Questions (FAQ)

Q: Can KLSR010.T be used as a direct replacement for 0LKS010.S?

A: KLSR010.T matches the critical electrical parameters (10A, 600 VAC, fast-blow response, CE/CSA/UL certification). Physical compatibility must be confirmed, as KLSR010.T is 1.252" longer (5.000" vs 3.748"). The fuse holder must accommodate this increased length.

Q: What is the difference between the 0LKS010.S and KLSR010.T?

A: Both are 10A, 600 VAC fast-blow cartridge fuses from Littelfuse. The KLSR010.T adds 250 VDC capability, increases breaking capacity from 10kA to 200kA AC (20kA DC), and is ROHS3 compliant. The 0LKS010.S is obsolete; KLSR010.T is an active product.

Q: Is LKS-10 compatible with the original 0LKS010.S holder?

A: LKS-10 is a 10A renewable link fuse from Eaton - Bussmann. Detailed specifications for voltage rating, response time, and physical dimensions are not provided in the available data. Compatibility verification with the original holder is required before use.

Q: Why is the 0LKS010.S obsolete?

A: The 0LKS010.S is listed as obsolete by Littelfuse Inc. KLSR010.T and other modern alternatives provide equivalent or enhanced functionality with current regulatory compliance and active manufacturing status.

Q: Are both substitutes RoHS compliant?

A: KLSR010.T is ROHS3 compliant. LKS-10 is RoHS compliant. The original 0LKS010.S is RoHS non-compliant. If RoHS compliance is a system requirement, either substitute is acceptable.

Q: What is the breaking capacity difference, and does it matter?

A: The 0LKS010.S has 10kA breaking capacity; KLSR010.T has 200kA AC and 20kA DC. Higher breaking capacity indicates the fuse can safely interrupt larger fault currents. For applications originally designed for 10kA, the KLSR010.T's higher capacity provides enhanced safety margin without compromising protection.
