Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 4420.0232 is determined by the following critical parameters:

• Current Rating: 25A (exact match required)
• Voltage Rating - AC: 277V (exact match required)
• Voltage Rating - DC: 60V or 65V (within acceptable tolerance for DC applications)
• Mounting Type: 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 2907574 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters, with a minor DC voltage rating variance (60V versus 65V) that remains within acceptable operational limits for this breaker category.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2907574 is the qualified substitute for the obsolete SCHURTER 4420.0232. Selection rationale is based on the following factors:

• Both components maintain identical current and AC voltage ratings (25A, 277V AC)
• Both components are ROHS3 compliant, ensuring regulatory alignment
• The Phoenix Contact part carries active product status, ensuring ongoing availability and supply chain continuity
• The DC voltage rating differential (60V versus 65V) is within acceptable operational tolerance for thermal magnetic breaker applications
• Both components feature identical mounting, actuation, and pole configurations, enabling direct mechanical and electrical integration into existing DIN rail assemblies

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2907574 be used as a direct replacement for the SCHURTER 4420.0232?

A: Yes. Both components share identical current ratings (25A), AC voltage ratings (277V), mounting type (DIN Rail), actuator type (Lever), and pole configuration (1-pole). The DC voltage rating difference (60V versus 65V) does not prevent substitution in standard thermal magnetic breaker applications.

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

A: The SCHURTER 4420.0232 is classified as obsolete, meaning it is no longer manufactured or supported by the original supplier. The Phoenix Contact 2907574 maintains active product status, ensuring continued availability, technical support, and supply chain reliability for new installations and replacements.

Q: Are there any compliance or certification concerns with substitution?

A: Both components are ROHS3 compliant and carry equivalent regulatory approvals. The Phoenix Contact 2907574 meets the same international standards applicable to thermal magnetic circuit breakers, ensuring compliance with system-level requirements.

Q: Does the packaging format affect substitution eligibility?

A: Packaging format (Bulk versus Box) does not affect electrical or mechanical compatibility. Selection of packaging is determined by procurement and inventory management requirements rather than functional substitution criteria.

Q: What is the inventory status for each part?

A: The SCHURTER 4420.0232 has 710 pieces available in stock as new original inventory. The Phoenix Contact 2907574 has 2378 pieces available in stock as new original inventory, providing greater supply availability for immediate procurement needs.
