Key Parameters

Substitute Part Grouping Explanation

Substitution of the LH600603C is determined by the following critical parameters that must remain constant:

• Current Rating: 60 A
• Voltage Rating: 600V
• Number of Circuits: 3
• Fuse Type: Cartridge
• Fuseholder Type: Block
• Termination Style: Box Lug
• Fuse Compatibility: Class H(K), Class R Fuses

The LFH600603CID qualifies as a direct substitute based on matching all critical electrical and functional parameters. The primary difference is the mounting configuration: the substitute uses DIN Rail mounting instead of chassis mount. This represents a mechanical variation that may require enclosure or panel redesign but does not affect electrical compatibility or fuse block functionality.

Parameter Comparison

Engineering Selection Recommendations

The LFH600603CID is the direct electrical equivalent to the LH600603C. Both components maintain identical current, voltage, circuit count, and fuse compatibility specifications. The substitute is currently in active production status, ensuring long-term availability and supply chain continuity.

The LFH600603CID carries ROHS3 compliance and REACH unaffected status, providing regulatory advantages over the obsolete LH600603C. The primary consideration for selection is mechanical integration: the DIN Rail mounting of the substitute requires panel or enclosure modification compared to the original chassis mount configuration. Electrical performance and fuse block functionality remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the LFH600603CID directly replace the LH600603C without modification?

A: Electrical substitution is direct. Mechanical integration requires adaptation due to different mounting types. The LH600603C uses chassis mount; the LFH600603CID uses DIN Rail mount. Panel or enclosure redesign may be necessary.

Q: Are the fuse cartridges compatible between these two blocks?

A: Both blocks accept identical Class H(K) and Class R cartridge fuses. Fuse cartridge compatibility is maintained across both models.

Q: What is the significance of the product status difference?

A: The LH600603C is obsolete, indicating discontinued production and limited future availability. The LFH600603CID is active production, ensuring reliable supply and support for new installations and replacements.

Q: Does RoHS compliance affect electrical performance?

A: RoHS compliance reflects manufacturing process standards and material composition. Electrical performance and current/voltage ratings remain identical. The ROHS3 compliance of the substitute provides regulatory alignment with modern environmental standards.

Q: Are there any circuit or current rating differences?

A: No. Both components are rated for 60 A at 600V with 3 circuits. All electrical specifications are identical.
