Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0KLC090.V is determined by strict alignment of the following critical parameters:

• Current Rating: 90A (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)
• Breaking Capacity: Minimum 200kA AC at rated voltage

The KAC-90 manufactured by Eaton - Bussmann Electrical Division meets all critical substitution criteria. Both parts share identical current and voltage ratings, cartridge fuse type, bolt mount configuration, and cylindrical blade terminal package. Both achieve the required 200kA breaking capacity at rated voltage. Minor dimensional variation (2.874" vs 2.750" length) remains within acceptable tolerance for bolt mount cartridge fuse applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 0KLC090.V and KAC-90 are active production parts with current inventory availability. Selection between these parts should be based on the following factors:

The 0KLC090.V offers broader regulatory approval coverage with CE, CSA, and UR certifications, making it suitable for applications requiring multi-region compliance. The KAC-90 carries UR certification and is suitable for applications where UR approval is the primary requirement.

Both parts meet RoHS compliance requirements. The 0KLC090.V is ROHS3 compliant, while the KAC-90 is RoHS compliant. Both achieve the required 200kA breaking capacity at 600 VAC rated voltage.

The dimensional difference of 0.124" (3.15mm) in length between the two parts must be verified against the specific bolt mount fixture design to ensure mechanical fit and proper electrical contact.

Frequently Asked Questions (FAQ)

Q: Can the KAC-90 be used as a direct replacement for the 0KLC090.V?

A: The KAC-90 meets all critical electrical parameters: 90A current rating, 600 VAC voltage rating, 200kA breaking capacity, cartridge fuse type, and bolt mount configuration. Mechanical fit must be verified due to the 0.124" length difference. Regulatory approval requirements must be confirmed for your specific application.

Q: What is the significance of the length difference between these two fuses?

A: The 0KLC090.V measures 2.874" in length while the KAC-90 measures 2.750" in length. Both maintain the same 1.000" diameter. This 0.124" difference may affect fit in existing bolt mount fixtures. Physical verification in your specific mounting assembly is required before substitution.

Q: Are both parts RoHS compliant?

A: Yes. The 0KLC090.V is ROHS3 compliant. The KAC-90 is RoHS compliant. Both meet RoHS requirements for hazardous substance restrictions.

Q: What are the regulatory approval differences?

A: The 0KLC090.V carries CE, CSA, and UR approvals. The KAC-90 carries UR approval. If your application requires CE or CSA certification, the 0KLC090.V is the appropriate choice. If UR approval is sufficient, both parts are acceptable.

Q: Are these fuses suitable for semiconductor applications?

A: The 0KLC090.V is specified for semiconductor applications. The KAC-90 is specified for electrical and industrial applications. Both achieve the same electrical performance at 90A 600 VAC with fast-blow response and 200kA breaking capacity. Application-specific requirements should be verified with your system design documentation.
