Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 4420.0401 is determined by strict equivalence across the following parameters:

• Current Rating: 500mA (exact match required)
• Voltage Rating - AC: 480V (exact match required)
• Voltage Rating - DC: 65V (exact match required for dual-voltage applications)
• Mounting Type: DIN Rail (form factor compatibility)
• Breaker Type: Thermal Magnetic (functional equivalence)
• Actuator Type: Lever (operational interface)
• Number of Poles: 3 (circuit configuration)

Two substitute parts meet these criteria. The Carlo Gavazzi GMB63H3PC0.5 matches all electrical parameters except DC voltage rating, which is not specified in its documentation. The Weidmüller 9913050003 provides complete parametric equivalence, including both AC and DC voltage ratings identical to the original part.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring exact parametric equivalence including both 480V AC and 65V DC ratings, the Weidmüller 9913050003 is the appropriate selection. This part is active in production, carries CSA C22.2 No 235, UL1077, and VDE certifications, and maintains RoHS compliance.

The Carlo Gavazzi GMB63H3PC0.5 is suitable for applications operating exclusively at 480V AC where DC voltage rating is not a functional requirement. This part is active in production and certified to CSA C22.2 No 5, IEC 60947-2, and UL489 standards.

Both substitutes are available in production quantities and carry REACH Unaffected status. Selection between them depends on whether dual-voltage (AC/DC) operation is required in the target application.

Frequently Asked Questions (FAQ)

Q: Can the Carlo Gavazzi GMB63H3PC0.5 replace the SCHURTER 4420.0401 in all applications?

A: The Carlo Gavazzi part matches all critical electrical parameters for AC operation at 480V and 500mA. However, it does not specify a DC voltage rating. If the application requires 65V DC operation, the Weidmüller 9913050003 is required.

Q: What certifications apply to each substitute part?

A: The Weidmüller 9913050003 carries CSA C22.2 No 235, UL1077, and VDE certifications. The Carlo Gavazzi GMB63H3PC0.5 carries CSA C22.2 No 5, IEC 60947-2, and UL489 certifications. Both meet North American and international standards for circuit breaker applications.

Q: Are there packaging differences between the substitutes?

A: Yes. The Carlo Gavazzi GMB63H3PC0.5 is supplied in box packaging, while the Weidmüller 9913050003 is supplied in bulk packaging. Packaging selection may affect procurement lead times and inventory management.

Q: Why is the SCHURTER 4420.0401 obsolete?

A: The part is classified as obsolete by the manufacturer. Active substitutes with identical or superior specifications are available from Carlo Gavazzi and Weidmüller, ensuring continued availability for new designs and replacement applications.

Q: Do both substitutes maintain RoHS compliance?

A: The Weidmüller 9913050003 is RoHS Compliant. The Carlo Gavazzi GMB63H3PC0.5 does not specify RoHS status in the provided documentation. For applications requiring RoHS compliance, the Weidmüller part is the confirmed selection.
