Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0KLC012.T is determined by strict alignment of the following parameters:

• Current Rating: 12A (exact match required)
• Voltage Rating (AC): 600 VAC (exact match required)
• Fuse Type: Cartridge (exact match required)
• Mounting Type: Bolt Mount (exact match required)
• Package / Case: Cylindrical, Blade Terminal (Bolt) (exact match required)
• Size / Dimension: 0.563" Dia x 1.874" L ± tolerance (mechanical compatibility required)
• Breaking Capacity @ Rated Voltage: 200kA AC minimum (performance requirement)
• Approval Agency: Compliance with UR certification (minimum requirement)

The KAC-12 manufactured by Eaton - Bussmann Electrical Division meets all substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The KAC-12 is a direct substitute for the 0KLC012.T based on electrical and mechanical parameter alignment. Both components carry UR approval certification, meeting regulatory requirements for industrial and semiconductor applications. The dimensional variance of 0.001" in length is within acceptable mechanical tolerance for bolt mount cartridge fuse installations. Both parts maintain RoHS compliance status, supporting environmental and regulatory requirements. Selection between these parts may be based on inventory availability, lead time, or established supplier relationships, as functional performance is equivalent.

Frequently Asked Questions (FAQ)

Q: Can the KAC-12 be used as a direct replacement for the 0KLC012.T in existing installations?

A: Yes. The KAC-12 meets all critical electrical parameters (12A, 600 VAC), mechanical specifications (cylindrical bolt mount, 0.563" Dia x 1.875" L), and regulatory certifications (UR approval). The 0.001" dimensional variance in length is within acceptable tolerance for bolt mount applications.

Q: What are the key parameters that determine substitution eligibility?

A: Current rating (12A), voltage rating (600 VAC), fuse type (cartridge), mounting type (bolt mount), package configuration (cylindrical blade terminal), and breaking capacity (200kA AC minimum) must match exactly. Approval agency certification (UR minimum) is required.

Q: Does the KAC-12 have the same response time as the 0KLC012.T?

A: The 0KLC012.T is specified as fast blow. The KAC-12 response time is not provided in the available data. Verify response time requirements for your specific application before selection.

Q: Are both parts RoHS compliant?

A: Yes. The 0KLC012.T is ROHS3 compliant, and the KAC-12 is RoHS compliant. Both meet environmental compliance requirements.

Q: What is the significance of the dimensional difference (0.001" in length)?

A: The 0KLC012.T measures 1.874" L while the KAC-12 measures 1.875" L. This 0.001" variance is negligible for bolt mount cartridge fuse installations and does not affect mechanical fit or electrical performance.
