KLM-15 Equivalent & Substitute Parts

Part Overview

The KLM-15 is a 15A 600VAC/VDC fast-blow fuse cartridge manufactured by Eaton - Bussmann Electrical Division. This component is designed for electrical and industrial applications requiring cartridge-style fuse protection in holder-based installations. The part maintains active product status with 839 units in current inventory. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and approval certifications align with the original specification, enabling direct replacement in compatible fuse holders.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the KLM-15 are identified based on strict equivalence across the following critical parameters:

• Current Rating: 15A
• Voltage Rating: 600 VAC / 600 VDC
• Fuse Type: Cartridge
• Response Time: Fast Blow
• Physical Dimensions: 0.406" Dia x 1.500" L (10.30mm x 38.10mm)
• Breaking Capacity: 100kA AC, 50kA DC
• Mounting Type: Requires Holder
• Approval Certifications: CE, CSA, UL

The KLKD015.T from Littelfuse Inc. meets all these criteria, enabling functional equivalence in holder-based installations.

Parameter Comparison

Engineering Selection Recommendations

Both the KLM-15 and KLKD015.T maintain active product status and comply with identical electrical and mechanical specifications. The KLKD015.T carries additional VDE certification beyond the base CE, CSA, and UL approvals present on the KLM-15. Both components are ROHS3 compliant and meet the same breaking capacity requirements. Selection between these parts depends on inventory availability and specific regional certification requirements. The dimensional tolerance variance (10.30mm vs 10.31mm diameter) is within standard manufacturing tolerances for cartridge fuses and does not affect holder compatibility.

Frequently Asked Questions (FAQ)

Q: Can KLKD015.T replace KLM-15 in existing installations? A: Yes. Both parts share identical current ratings (15A), voltage ratings (600 VAC/VDC), response time (fast blow), physical dimensions (0.406" Dia x 1.500" L), and breaking capacity (100kA AC, 50kA DC). They are mechanically and electrically interchangeable in compatible fuse holders.

Q: Are there differences in approval certifications? A: The KLKD015.T includes VDE certification in addition to CE, CSA, and UL certifications. Both parts meet the base certification requirements. The additional VDE approval on the substitute does not create incompatibility.

Q: What determines substitution eligibility for cartridge fuses? A: Substitution requires matching current rating, voltage rating (AC and DC), response time, physical dimensions, breaking capacity, and holder compatibility. All these parameters are identical between KLM-15 and KLKD015.T.

Q: Does packaging type affect substitution? A: Packaging (bulk vs. box) does not affect electrical or mechanical performance. It reflects only the distribution format and does not impact component functionality or holder compatibility.

Q: Are there temperature or environmental differences? A: Operating temperature data is not provided for either part. Both components are ROHS3 compliant and REACH unaffected, meeting equivalent environmental standards.
