Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LT600301SR is determined by strict equivalence across the following parameters:

• Voltage Rating: 600V (exact match required)
• Current Rating: 30 A (exact match required)
• Fuse Size: 0.563" Dia x 1.5" L (exact match required)
• Fuse Type: Cartridge (exact match required)
• Number of Circuits: 1 (exact match required)
• Mounting Type: Chassis Mount (exact match required)
• Termination Style: Screw Terminal (exact match required)
• Fuseholder Type: Block (exact match required)

The substitute part T60030-1SR meets all specified electrical and mechanical parameters, establishing direct functional equivalence with the obsolete LT600301SR.

Engineering Selection Recommendations

The T60030-1SR from Eaton - Bussmann Electrical Division is the direct functional equivalent for the obsolete LT600301SR. Selection of the T60030-1SR is supported by:

• Product Status: The T60030-1SR maintains active production status, ensuring ongoing availability and supply chain reliability.
• Electrical Equivalence: Identical voltage (600V), current (30A), and fuse class (Class T) specifications.
• Mechanical Compatibility: Matching fuse cartridge dimensions (0.563" Dia x 1.5" L), mounting configuration (chassis mount), and termination method (screw terminal).
• Compliance: The T60030-1SR is RoHS compliant, meeting current environmental and regulatory standards.

Frequently Asked Questions (FAQ)

Q: Can the T60030-1SR be used as a direct replacement for the LT600301SR?

A: Yes. The T60030-1SR meets all electrical and mechanical specifications of the LT600301SR, including voltage rating (600V), current rating (30A), fuse size (0.563" Dia x 1.5" L), mounting type (chassis mount), and termination style (screw terminal). Physical installation and electrical performance are equivalent.

Q: What is the primary reason for substitution?

A: The LT600301SR is classified as obsolete. The T60030-1SR provides continued access to functionally identical 600V, 30A single-circuit cartridge fuse block technology from an active manufacturer.

Q: Are there packaging differences between these parts?

A: The LT600301SR is packaged as individual units, while the T60030-1SR is supplied in bulk packaging. Both formats contain the same component with identical electrical and mechanical characteristics.

Q: Does the RoHS compliance difference affect substitution?

A: The T60030-1SR is RoHS compliant, whereas the LT600301SR is not. For applications subject to RoHS requirements or environmental regulations, the T60030-1SR is the appropriate selection. For legacy systems without such constraints, both parts remain functionally equivalent.

Q: Will the T60030-1SR work with Class T fuses?

A: Yes. The T60030-1SR is designed for Class T fuses in the standard 0.563" diameter by 1.5" length cartridge format, identical to the LT600301SR specification.
