KTS-R-45 Equivalent & Substitute Parts

Part Overview

The KTS-R-45 is a fast-acting AC/DC fuse manufactured by Eaton - Bussmann Electrical Division, classified as a FUSE LIMITRON FAST ACTING component. This part is currently active in production with RoHS compliance certification. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct functional replacement in applications where the main part becomes unavailable or when inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KTS-R-45 is based on alignment of the following critical parameters:

• Current Rating: 45A
• Voltage Rating - AC: 600 VAC
• Voltage Rating - DC: 300 VDC
• Response Time: Fast Blow
• Fuse Type: Cartridge
• Class: RK1
• Regulatory Compliance: CE, CSA, UL approval
• RoHS Compliance Status

The KLSR045.T from Littelfuse Inc. meets these electrical and mechanical criteria, qualifying it as a functional equivalent for the KTS-R-45 in applications requiring a 45A fast-acting fuse with dual AC/DC voltage ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the KTS-R-45 and KLSR045.T are active production components with equivalent electrical specifications. The KTS-R-45 is supplied in bulk packaging, while the KLSR045.T is supplied in box packaging. Both parts carry RoHS compliance certification and hold identical regulatory approvals (CE, CSA, UL). The KLSR045.T includes a breaking capacity specification of 200kA AC and 20kA DC at rated voltage. Selection between these parts should be based on packaging requirements, inventory availability, and established supplier relationships.

Frequently Asked Questions (FAQ)

Q: Can the KLSR045.T directly replace the KTS-R-45 in existing applications?

A: Yes. Both parts share identical electrical ratings (45A, 600 VAC, 300 VDC), response time classification (Fast Blow), fuse type (Cartridge), and RK1 class designation. The primary difference is packaging format (bulk versus box).

Q: What is the significance of the RK1 class rating?

A: RK1 classification indicates a current-limiting fuse designed for industrial and commercial electrical distribution systems. This class designation ensures consistent performance characteristics and breaking capacity across equivalent parts.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (bulk or box) does not affect the electrical or mechanical performance of the fuse. It reflects only the quantity and presentation method for inventory and distribution purposes.

Q: Are there any compliance differences between these parts?

A: Both parts comply with RoHS regulations and hold identical regulatory approvals (CE, CSA, UL). The KLSR045.T carries ROHS3 compliance, which represents a more recent revision of the RoHS standard.

Q: What mounting consideration applies to the KLSR045.T?

A: The KLSR045.T requires a holder for installation. Verify that the application circuit includes an appropriate cartridge fuse holder rated for 45A, 600 VAC/300 VDC operation.
