Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for thermal magnetic circuit breakers is determined by strict alignment of electrical and mechanical parameters. The primary criteria are:

• Current rating: 5A (exact match required)
• AC voltage rating: 277V (exact match required)
• DC voltage rating: 60V or 65V (within acceptable tolerance for DC applications)
• Mounting configuration: DIN rail (exact match required)
• Breaker type: Thermal magnetic (exact match required)
• Actuator type: Lever (exact match required)
• Number of poles: 1 (exact match required)

The Phoenix Contact 2907630 meets all substitution criteria with a DC voltage rating of 60V, which is within the operational envelope for DC applications and represents a functionally equivalent alternative to the obsolete SCHURTER component.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2907630 is the identified substitute for the obsolete SCHURTER 4420.0513. Both components maintain identical electrical ratings for AC operation at 277V and 5A, with DC voltage ratings of 65V and 60V respectively. The Phoenix Contact component carries active product status with current manufacturing availability, ensuring supply chain continuity. Both parts comply with ROHS3 requirements and carry equivalent international safety certifications. The 5V difference in DC voltage rating (65V versus 60V) does not compromise functional equivalence for standard industrial applications within the specified voltage envelope.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2907630 directly replace the SCHURTER 4420.0513 in existing installations?

A: Yes. Both components share identical current ratings (5A), AC voltage ratings (277V), mounting configuration (DIN rail), breaker type (thermal magnetic), actuator type (lever), and pole count (1). The DC voltage rating difference of 5V does not affect functional compatibility within standard industrial operating parameters.

Q: What is the significance of the DC voltage rating difference between 65V and 60V?

A: Both ratings operate within the same functional envelope for DC applications. The 60V rating of the Phoenix Contact component is suitable for DC circuits operating at or below 60V. Applications requiring operation above 60V DC should be evaluated against specific system requirements.

Q: Are there compliance or certification differences between these components?

A: Both components are ROHS3 compliant and carry equivalent international safety certifications including IEC 60934 and UL1077. No compliance gaps exist between the two parts.

Q: What packaging is available for the substitute part?

A: The Phoenix Contact 2907630 is supplied in box packaging, suitable for standard component handling and storage in industrial environments.

Q: Is the SCHURTER 4420.0513 still available for procurement?

A: The SCHURTER component is classified as obsolete. The Phoenix Contact 2907630 is an active product with current manufacturing and inventory availability.
