SCHURTER 7024.9240 Equivalent & Substitute Parts

Part Overview

The SCHURTER 7024.9240 is a 2A 300VAC fast-blow cartridge fuse in 5AG package format (10mm x 38mm). This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and component procurement. The fuse is designed for electrical and industrial applications requiring fast-response overcurrent protection in AC circuits rated up to 300VAC.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 7024.9240 is determined by the following critical parameters:

• Current Rating: 2A (must match exactly)
• Fuse Type: Cartridge (must match exactly)
• Package / Case: 5AG, 10mm x 38mm (must match exactly)
• Response Time: Fast Blow (must match exactly)
• Voltage Rating - AC: Minimum 300VAC (equal or higher acceptable)
• Mounting Type: Requires Holder (must match exactly)

The Eaton - Bussmann KTK-2 meets all substitution criteria. While the KTK-2 has a higher voltage rating (600VAC) and breaking capacity (100kA), these represent enhanced performance characteristics that do not prevent substitution in applications designed for the original 300VAC component. The identical current rating, package format, response time, and mounting requirements ensure mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Eaton - Bussmann KTK-2 is the direct substitute for the obsolete SCHURTER 7024.9240. Selection is based on the following engineering factors:

• Active product status ensures ongoing availability and supply chain continuity
• Identical current rating (2A) and package format (5AG, 10mm x 38mm) guarantee mechanical fit and electrical performance in the original circuit
• Higher voltage rating (600VAC vs. 300VAC) and breaking capacity (100kA vs. 10kA) provide enhanced safety margins without affecting operation in 300VAC applications
• Dual certification (CSA and UL) exceeds the original single certification (CSA), supporting broader regulatory compliance requirements
• ROHS3 compliance maintained across both components

Frequently Asked Questions (FAQ)

Q: Can the KTK-2 be used as a direct replacement for the SCHURTER 7024.9240?

A: Yes. The KTK-2 matches all critical substitution parameters: 2A current rating, fast-blow response, 5AG cartridge package (10mm x 38mm), and holder-mount configuration. The higher voltage and breaking capacity ratings do not prevent substitution in 300VAC circuits.

Q: What is the significance of the higher voltage rating on the KTK-2?

A: The KTK-2 is rated for 600VAC, compared to the original 300VAC rating. This represents a performance enhancement that ensures the substitute component operates safely in the original application. Higher voltage ratings do not cause incompatibility in lower-voltage circuits.

Q: Are there any mechanical differences between these fuses?

A: Physical dimensions are virtually identical. Both components use the 5AG package format with 10mm diameter and approximately 38mm length. Both require a fuse holder for installation. No mechanical modifications are necessary for substitution.

Q: Why is the KTK-2 breaking capacity (100kA) higher than the original (10kA)?

A: Breaking capacity indicates the maximum fault current a fuse can safely interrupt. The higher breaking capacity of the KTK-2 provides additional safety margin and is not a limitation for use in circuits designed for the original component.

Q: Does the KTK-2 have the same certifications as the SCHURTER 7024.9240?

A: The KTK-2 holds CSA and UL certifications, while the original holds CSA certification. The additional UL certification on the substitute provides broader regulatory acceptance without reducing compatibility.

Q: Is the KTK-2 currently available?

A: Yes. The KTK-2 has active product status, ensuring ongoing manufacturing and supply availability, unlike the obsolete SCHURTER 7024.9240.
