Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0KLC030.T is determined by strict equivalence across the following critical parameters:

• Current Rating: 30A (exact match required)
• Voltage Rating: 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)
• Physical Dimensions: 0.563" Dia x 1.874" L ±0.001" (mechanical compatibility required)
• Breaking Capacity: Minimum 200kA AC at rated voltage (performance requirement)

The KAC-30 manufactured by Eaton - Bussmann Electrical Division meets all critical substitution criteria and is identified as the manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The KAC-30 is a direct functional equivalent to the 0KLC030.T based on electrical and mechanical parameter alignment. Both components are active products with current manufacturing status and regulatory compliance certifications. The KAC-30 carries UR approval, which is a subset of the 0KLC030.T certifications (CE, CSA, UR). Physical dimensions are within acceptable mechanical tolerance (0.001" variation in length). Selection between these parts should be based on availability, lead time, and system certification requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the KAC-30 be used as a direct replacement for the 0KLC030.T?

A: Yes. The KAC-30 meets all critical electrical parameters (30A, 600 VAC, 200kA breaking capacity) and mechanical specifications (cylindrical cartridge, bolt mount, compatible dimensions). Both components are cartridge fuses with identical current and voltage ratings.

Q: Are there dimensional differences between these parts?

A: The length dimension differs by 0.001" (0.563" Dia x 1.874" L for 0KLC030.T versus 0.563" Dia x 1.875" L for KAC-30). This variation is within standard mechanical tolerance for bolt-mount cartridge fuses and does not affect functional compatibility.

Q: What certifications does each part carry?

A: The 0KLC030.T carries CE, CSA, and UR approvals. The KAC-30 carries UR approval. If your application requires CE or CSA certification specifically, verify that system-level certification permits substitution with a UR-only component.

Q: Is the response time specification the same for both parts?

A: The 0KLC030.T is specified as Fast Blow. The KAC-30 response time specification is not provided in the available data. Confirm response time requirements with the component manufacturer if fast-blow characteristics are critical to your application.

Q: Are both parts RoHS compliant?

A: Yes. The 0KLC030.T is ROHS3 Compliant. The KAC-30 is RoHS Compliant. Both meet RoHS requirements for lead-free construction.
