ECSR10 Equivalent & Substitute Parts Reference

Part Overview

The ECSR10 is a 10A 600VAC cartridge fuse manufactured by Eaton - Bussmann Electrical Division. This slow-blow fuse is designed for electrical and industrial applications requiring a cartridge-style fuse that operates in a dedicated holder. The part is currently active in production with 680 units in stock. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and approval certifications align with the original specification, enabling direct replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

The FRS-R-10 qualifies as a substitute for the ECSR10 based on the following alignment of critical parameters:

Matching Electrical Specifications:

• Current Rating: 10A (identical)
• Voltage Rating - AC: 600 VAC (identical)
• Response Time: Slow Blow (identical)
• Class: RK5 (identical)
• Breaking Capacity @ Rated Voltage: 200kA AC (identical)

Matching Mechanical Specifications:

• Fuse Type: Cartridge (identical)
• Mounting Type: Requires Holder (identical)
• Package / Case: Cartridge, Non-Standard (identical)
• Diameter: 0.810" (20.57mm) (identical)

Matching Compliance & Certifications:

• Approval Agency: CE, CSA, UL (identical)
• RoHS Status: RoHS Compliant (identical)

Additional Capability: The FRS-R-10 provides supplementary DC voltage rating (300 VDC, 20kA DC breaking capacity) not present in the ECSR10, making it suitable for applications requiring either AC or DC operation.

Dimensional Consideration: The FRS-R-10 length is 3.00" (76.20mm) compared to the ECSR10 length of 5.00" (127.00mm). Both fit standard cartridge holders, but physical space constraints in the installation location must be verified.

Parameter Comparison

Engineering Selection Recommendations

Both the ECSR10 and FRS-R-10 are active products from the same manufacturer with identical electrical ratings, response characteristics, and approval certifications (CE, CSA, UL). Both are RoHS compliant and suitable for electrical and industrial applications.

The FRS-R-10 is a direct substitute for AC applications at 600 VAC, 10A. The primary selection consideration is physical length: the FRS-R-10 is 2.00" shorter than the ECSR10. Verify that the installation location accommodates the shorter cartridge length before substitution. If DC voltage capability is required in the circuit, the FRS-R-10 provides 300 VDC rating, whereas the ECSR10 is AC-only.

Frequently Asked Questions (FAQ)

Q: Can the FRS-R-10 directly replace the ECSR10 in an existing installation?

A: Yes, for AC applications at 600 VAC, 10A. Both fuses have identical electrical ratings, response time, class designation, and approval certifications. Verify that the shorter physical length of the FRS-R-10 (3.00" vs. 5.00") fits within the available space in the fuse holder assembly.

Q: What is the difference between these two cartridge fuses?

A: The primary differences are physical length and DC voltage capability. The FRS-R-10 is shorter (3.00" vs. 5.00") and includes a 300 VDC rating with 20kA DC breaking capacity. The ECSR10 is AC-only. All other electrical parameters—current, AC voltage, response time, class, and breaking capacity—are identical.

Q: Are both fuses approved for the same applications?

A: Yes. Both hold CE, CSA, and UL approvals and are rated for electrical and industrial applications. Both are RoHS compliant.

Q: Does the length difference affect electrical performance?

A: No. Cartridge fuse length does not affect electrical performance. Length is a mechanical consideration for physical fit within the holder assembly only.

Q: Which fuse should I select if my circuit operates on both AC and DC?

A: Select the FRS-R-10, which is rated for both 600 VAC and 300 VDC operation. The ECSR10 is AC-only.
