Key Parameters

Substitute Part Grouping Explanation

The Littelfuse Inc. L60030M3SQ qualifies as a functional equivalent based on the following critical parameters:

• Voltage Rating: Both parts are rated for 600V operation
• Current Rating: Both parts are rated for 30A
• Number of Circuits: Both parts feature 3-circuit configuration
• Fuse Type Compatibility: The L60030M3SQ accepts 5AG, 13/32" x 1-1/2" (Midget) cartridge fuses, which are the standard midget fuse format
• Product Status: Both parts are active and in production
• Regulatory Compliance: Both parts meet ROHS3 requirements

The primary difference is the mounting configuration: the Mersen 30313 is a standard fuseblock, while the Littelfuse L60030M3SQ is specifically designed for chassis mount applications. This distinction is mechanical rather than electrical and does not affect the core protective function when mounting requirements are compatible.

Parameter Comparison

Engineering Selection Recommendations

Both the Mersen 30313 and Littelfuse L60030M3SQ are suitable for 600V, 30A, 3-circuit fuse block applications. Selection between these parts should be based on:

• Mounting Requirements: The Littelfuse L60030M3SQ is specified for chassis mount applications. Verify that your application supports chassis mounting before substitution.
• Termination Compatibility: The Littelfuse part offers screw terminal and quick connect options. Confirm that your circuit design accommodates these termination styles.
• Inventory Availability: The Mersen part currently has higher inventory (2100 units vs. 1649 units).
• Regulatory Compliance: Both parts meet ROHS3 requirements and are suitable for applications requiring environmental compliance.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse L60030M3SQ directly replace the Mersen 30313?

A: Electrical compatibility is confirmed based on matching voltage (600V), current (30A), and circuit count (3). However, the Littelfuse part is designed for chassis mount applications. Verify that your installation supports this mounting configuration before substitution.

Q: What fuse types are compatible with these fuseblocks?

A: Both parts are designed for midget cartridge fuses rated 5AG, 13/32" x 1-1/2" format. Ensure that replacement fuses meet this specification.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the Mersen 30313 and Littelfuse L60030M3SQ are ROHS3 compliant and suitable for applications requiring environmental compliance.

Q: What are the key differences between these parts?

A: The primary differences are mounting type (standard vs. chassis mount) and termination options (not specified for Mersen vs. screw terminal/quick connect for Littelfuse). Electrical ratings and circuit configuration are identical.

Q: Which part should I select for new designs?

A: Selection depends on your specific mounting and termination requirements. For chassis mount applications, the Littelfuse L60030M3SQ is the appropriate choice. For standard mounting applications, the Mersen 30313 is suitable. Both parts are active and in production.
