Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the KTS-R-150 are identified based on the following critical parameters that determine functional equivalence:

• Current Rating: 150A nominal capacity
• Fuse Type: Fast-acting response characteristic
• AC/DC Voltage Compatibility: Dual-voltage rated operation
• Regulatory Compliance: RoHS and international certifications (CE, CSA, UL)
• Electrical Classification: Industrial-grade overcurrent protection

The KLSR150.X from Littelfuse Inc. qualifies as a substitute based on matching current rating (150A), fast-blow response time, dual voltage operation (600 VAC / 300 VDC), and equivalent regulatory compliance status. Both parts serve identical functional roles in electrical protection circuits.

Parameter Comparison

Engineering Selection Recommendations

Both the KTS-R-150 and KLSR150.X are active production components with current RoHS compliance certifications. Selection between these parts should be based on:

• Packaging requirements: KTS-R-150 is supplied in bulk packaging; KLSR150.X is supplied in box packaging
• Holder compatibility: KLSR150.X requires a compatible fuse holder for installation
• Regulatory certifications: KLSR150.X carries explicit CE, CSA, and UL approvals; KTS-R-150 certification details are not specified in available data
• Supply chain availability: Both parts maintain active inventory status

Frequently Asked Questions (FAQ)

Q: Can KLSR150.X directly replace KTS-R-150 in all applications?

A: Both parts share identical current ratings (150A) and fast-acting response characteristics. However, KLSR150.X is a cartridge-type fuse requiring a compatible holder, whereas KTS-R-150 packaging type is not specified. Mechanical fit and holder compatibility must be verified before substitution.

Q: What are the voltage limitations for these fuses?

A: KLSR150.X is rated for 600 VAC and 300 VDC operation. Voltage ratings for KTS-R-150 are not provided in the available technical data. Confirm voltage compatibility with your application requirements before selection.

Q: Are both parts RoHS compliant?

A: Yes. KTS-R-150 is RoHS Compliant; KLSR150.X is ROHS3 Compliant. Both meet current RoHS regulatory requirements.

Q: What is the breaking capacity difference?

A: KLSR150.X specifies a breaking capacity of 200kA AC and 20kA DC at rated voltage. Breaking capacity specifications for KTS-R-150 are not available in the provided data.

Q: Does packaging affect substitution eligibility?

A: Yes. KTS-R-150 is supplied in bulk packaging; KLSR150.X is supplied in box packaging. Procurement quantity requirements and storage conditions may influence part selection.
