Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 9925750000 is determined by the following critical parameters:

• Current Rating: 20A (exact match required)
• Voltage Rating - AC: 480V (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Actuator Type: Lever (exact match required)
• Number of Poles: 2 (exact match required)
• Voltage Rating - DC: Minimum 110V (equal or higher acceptable)

The identified substitute part meets all mandatory electrical and mechanical parameters. The DC voltage rating of the substitute exceeds the original specification, which is acceptable for direct substitution purposes.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 2480390000 (MCB 1077 series) is the direct substitute for the obsolete 9925750000. This part maintains identical electrical specifications for AC voltage, DC voltage, current rating, and mechanical configuration. The substitute carries active product status and holds multiple regulatory approvals including CE, CSA C22.2 No 5, CSA C22.2 No 235, TÜV, UL1077, and VDE certifications. The substitute is RoHS compliant, whereas compliance status for the original part is not specified. Both parts are manufactured by Weidmüller and are designed for identical DIN rail mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the 2480390000 directly replace the 9925750000 in existing installations?

A: Yes. Both parts are 2-pole thermal magnetic circuit breakers with 20A current rating and 480V AC voltage rating. The substitute's 125V DC rating exceeds the original 110V DC specification, making it suitable for direct substitution in all applications where the original part was used.

Q: What is the significance of the product status difference?

A: The original 9925750000 is obsolete and no longer manufactured. The 2480390000 is in active production, ensuring availability for new installations and replacements. This makes the substitute the recommended choice for long-term system reliability.

Q: Are there packaging differences between these parts?

A: The original part number does not specify packaging details. The substitute is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Do the regulatory certifications differ?

A: The substitute carries documented approvals (CE, CSA, TÜV, UL1077, VDE). The original part's certification status is not specified in available documentation. The substitute's certifications support compliance requirements for industrial control applications.

Q: Is the DC voltage rating increase a concern for compatibility?

A: No. A higher DC voltage rating on the substitute provides additional safety margin and does not affect performance in applications designed for the original 110V DC specification.
