Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the KLM-30 are qualified based on the following electrical and mechanical parameters:

• Current Rating: 30A (exact match required)
• Voltage Rating: 600 VAC / 600 VDC (exact match required)
• Fuse Type: Cartridge (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity: 100kA AC / 50kA DC (exact match required)
• Physical Dimensions: 0.406" Dia x 1.500" L (exact match required)
• Mounting Type: Requires Holder (exact match required)

The identified substitutes are manufactured by Littelfuse Inc. under the POWR-GARD® KLKD series. Both substitute parts meet all critical electrical parameters and physical dimensions required for direct replacement in applications currently using the KLM-30.

Parameter Comparison

Engineering Selection Recommendations

Both KLKD030.HXR and KLKD030.T cartridge fuses are direct electrical and mechanical equivalents to the KLM-30. Selection between these options depends on packaging requirements and certification scope:

KLKD030.T is the preferred substitute when CSA certification is required, as it carries CE, CSA, and UL approvals matching the KLM-30 certification profile. This part is available in box packaging with 18,552 units in inventory.

KLKD030.HXR is suitable for applications requiring CE and UL certifications only. This variant is supplied in bulk packaging with 882 units in inventory.

All three parts maintain ROHS3 compliance and are rated for identical electrical performance in 600 VAC/VDC circuits with 30A current protection and fast-blow response characteristics.

Frequently Asked Questions (FAQ)

Q: Can KLKD030.HXR and KLKD030.T be used interchangeably with KLM-30?

A: Both Littelfuse POWR-GARD® KLKD cartridge fuses meet all electrical and mechanical specifications of the KLM-30. Physical dimensions, current rating, voltage rating, breaking capacity, and response time are identical. Compatibility depends on certification requirements for your specific application.

Q: What is the difference between KLKD030.HXR and KLKD030.T?

A: The primary differences are packaging format and certification scope. KLKD030.T includes CSA certification and is supplied in box packaging, while KLKD030.HXR is supplied in bulk packaging and carries CE and UL certifications only. Both are electrically and mechanically identical.

Q: Are these cartridge fuses compatible with existing KLM-30 holders?

A: Yes. All three fuses share identical physical dimensions (0.406" Dia x 1.500" L) and require the same holder type. Direct installation in existing KLM-30 holders is supported.

Q: Do the substitute parts maintain the same breaking capacity?

A: Yes. Both KLKD030.HXR and KLKD030.T are rated for 100kA AC and 50kA DC breaking capacity, matching the KLM-30 specification.

Q: Are these parts RoHS compliant?

A: Yes. All three cartridge fuses are ROHS3 compliant and REACH unaffected.
