Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ATM10 are qualified based on the following critical parameters:

• Current Rating: 10A (exact match required)
• Voltage Rating - AC: 600 VAC (exact match required)
• Package / Case: 5AG, 10mm x 38mm (Midget) (exact match required)
• Fuse Type: Cartridge (exact match required)
• Response Time: Fast Blow (exact match required)
• Product Status: Active (operational availability)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

Three substitute parts meet these criteria: 0KLK010.T (Littelfuse Inc.), KLKR010.T (Littelfuse Inc.), and KTK-10 (Eaton - Bussmann Electrical Division). All three maintain identical current, AC voltage, physical dimensions, and response characteristics as the ATM10.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (0KLK010.T, KLKR010.T, and KTK-10) are qualified replacements for the ATM10 based on matching electrical and mechanical specifications. Selection among these alternatives should be based on:

• Approval Agency requirements: 0KLK010.T includes QPL certification; KLKR010.T and KTK-10 carry standard UL and CSA approvals
• DC voltage rating requirements: 0KLK010.T supports 500 VDC; KLKR010.T supports 300 VDC; KTK-10 does not specify DC rating
• Breaking capacity: 0KLK010.T and KTK-10 provide 100kA AC; KLKR010.T provides 200kA AC
• Packaging format: 0KLK010.T and KTK-10 are supplied in Bulk; KLKR010.T is supplied in Box
• Inventory availability: All three parts maintain active stock levels

Frequently Asked Questions (FAQ)

Q: Can 0KLK010.T, KLKR010.T, and KTK-10 be used interchangeably with ATM10?

A: Yes, all three parts meet the core electrical and mechanical requirements for direct substitution. They share identical current ratings (10A), AC voltage ratings (600 VAC), physical dimensions (5AG, 10mm x 38mm), and response characteristics (Fast Blow). Selection depends on specific application requirements regarding DC voltage rating, breaking capacity, and certification needs.

Q: What is the difference between 0KLK010.T and KLKR010.T?

A: Both are Littelfuse POWR-GARD cartridge fuses with 10A and 600 VAC ratings. The primary differences are: 0KLK010.T supports 500 VDC with 100kA AC breaking capacity, while KLKR010.T supports 300 VDC with 200kA AC breaking capacity. KLKR010.T is classified as Class CC; 0KLK010.T does not specify a class designation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, ATM10, 0KLK010.T, KLKR010.T, and KTK-10 are all ROHS3 compliant, meeting current environmental and regulatory standards.

Q: What certifications do these fuses carry?

A: 0KLK010.T carries CE, CSA, QPL, and UL approvals. KLKR010.T carries CE, CSA, and UL approvals. KTK-10 carries CSA and UL approvals. All three meet standard industrial safety requirements.

Q: Do these fuses require a holder for installation?

A: Yes, all substitute parts are cartridge fuses that require a compatible 5AG holder for installation. They are not designed for direct panel mounting.
