Key Parameters

Substitute Part Grouping Explanation

The Weidmüller 2480200000 qualifies as a parametric equivalent to the 2480920000 based on the following critical parameters:

• Current Rating: 40A (identical)
• Voltage Rating - AC: 277V (identical)
• Voltage Rating - DC: 60V (identical)
• Number of Poles: 1 (identical)
• Breaker Type: Thermal Magnetic (identical)
• Mounting Type: DIN Rail (identical)
• Actuator Type: Lever (identical)
• Series: MCB 1077 (identical)
• Approval Agencies: CE, CSA C22.2 No 5, CSA C22.2 No 235, TUV, UL1077, VDE (identical)
• RoHS Status: RoHS Compliant (identical)

The primary distinction between these parts is the base product number designation (SU1D4 versus SU1C4), which reflects internal design variants within the same electrical and mechanical specification class. Both parts maintain identical functional performance and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the 2480920000 and 2480200000 are active production parts with identical electrical ratings, mechanical form factors, and regulatory certifications. Selection between these parts should be based on availability and application-specific requirements. Both parts satisfy UL1077, VDE, TUV, and CSA standards, making them suitable for North American and European industrial control applications. The RoHS compliance status is equivalent for both variants, ensuring environmental regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the 2480200000 be used as a direct replacement for the 2480920000?

A: Yes. Both parts share identical electrical ratings (40A, 277V AC, 60V DC), mechanical mounting (DIN rail, single-pole, lever actuator), and regulatory approvals. The base product number difference (SU1D4 versus SU1C4) does not affect functional compatibility.

Q: Are there any voltage or current limitations when substituting?

A: No. The substitute part maintains the same voltage and current specifications: 40A continuous rating, 277V AC maximum, and 60V DC maximum. No derating or application adjustment is required.

Q: Do both parts carry the same certifications?

A: Yes. Both parts are certified to CE, CSA C22.2 No 5, CSA C22.2 No 235, TUV, UL1077, and VDE standards. Regulatory compliance is equivalent.

Q: Is there a difference in RoHS compliance?

A: No. Both parts are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the difference between the base product numbers SU1D4 and SU1C4?

A: The base product number designates internal design variants within the MCB 1077 series. Both variants meet identical electrical and mechanical specifications and are functionally interchangeable.
