ECNR60 Equivalent & Substitute Parts

Part Overview

The ECNR60 is a 60A cartridge fuse rated for 250 VAC and 125 VDC operation, manufactured by Eaton - Bussmann Electrical Division. This slow-blow fuse cartridge is designed for electrical and industrial applications requiring RK5 class protection with a breaking capacity of 200kA at rated voltage. The part is currently active in production with 967 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory availability, application-specific compliance needs, or design standardization across product lines.

Substitute Part Grouping Explanation

Substitution eligibility for the ECNR60 is determined by strict equivalence across the following critical parameters:

• Current Rating: 60A (exact match required)
• Voltage Rating: 250 VAC / 125 VDC (exact match required)
• Fuse Type: Cartridge (exact match required)
• Response Time: Slow Blow (exact match required)
• Class: RK5 (exact match required)
• Physical Dimensions: 0.810" Dia x 3.00" L (exact match required)
• Mounting Configuration: Requires Holder (exact match required)

The FRN-R-60 meets all electrical and mechanical substitution criteria. Both parts share identical current ratings, voltage specifications, fuse classification, response characteristics, and physical form factors. Both are approved by CE, CSA, and UL certification bodies.

Parameter Comparison

Engineering Selection Recommendations

The FRN-R-60 is a direct electrical and mechanical equivalent to the ECNR60. Both parts are manufactured by Eaton - Bussmann Electrical Division and carry identical certifications from CE, CSA, and UL authorities. Both are active products with current production status.

The primary distinction between these parts is RoHS compliance status. The ECNR60 is RoHS compliant, while the FRN-R-60 is RoHS non-compliant. Selection between these parts should be based on the specific regulatory requirements of the end application. Applications subject to RoHS directives require the ECNR60. Applications without RoHS requirements may use either part based on availability and inventory considerations.

Frequently Asked Questions (FAQ)

Q: Can the FRN-R-60 be used as a direct replacement for the ECNR60 in all applications?

A: The FRN-R-60 is electrically and mechanically equivalent to the ECNR60. However, RoHS compliance requirements must be evaluated for the specific application. If RoHS compliance is mandated, the ECNR60 must be used. If RoHS compliance is not required, the FRN-R-60 is a valid substitute.

Q: Are the physical dimensions identical between ECNR60 and FRN-R-60?

A: Yes. Both parts have identical cartridge dimensions of 0.810" diameter by 3.00" length (20.57mm x 76.20mm). Both require the same holder configuration.

Q: Do both parts have the same breaking capacity?

A: Both parts have a breaking capacity of 200kA at rated voltage. The FRN-R-60 specification additionally notes 20kA DC breaking capacity.

Q: What certifications apply to both parts?

A: Both the ECNR60 and FRN-R-60 carry CE, CSA, and UL approvals, confirming compliance with international electrical safety standards.

Q: Are there any differences in response time or fuse class?

A: No. Both parts are slow-blow fuses classified as RK5, providing identical protection characteristics and response behavior.
