Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 4420.0242 is determined by the following critical parameters:

• Current Rating: 25A (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: 3 (exact match required)

The Phoenix Contact 2907623 qualifies as a substitute because it matches all mandatory electrical and mechanical parameters. The DC voltage rating differs (125V DC versus 65V DC on the original), which represents an enhancement in capability rather than a limitation, as the substitute maintains full compatibility with the AC specifications while providing extended DC voltage tolerance.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2907623 is the qualified substitute for the obsolete SCHURTER 4420.0242. Both components maintain ROHS3 compliance and carry equivalent regulatory standing. The substitute is currently in active production status, ensuring long-term availability and supply chain continuity. The elevated DC voltage rating of the Phoenix Contact unit (125V versus 65V) does not compromise compatibility in applications designed for the original 65V DC specification, as the substitute maintains superior performance margins in this parameter. Both components satisfy the same approval standards including UL1077, IEC 60934, and CSA certifications, confirming functional and safety equivalence for direct replacement in DIN rail-mounted thermal magnetic circuit breaker applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2907623 directly replace the SCHURTER 4420.0242 in existing installations?

A: Yes. Both components share identical current ratings (25A), AC voltage ratings (480V), mounting configuration (DIN rail), breaker type (thermal magnetic), actuator style (lever), and pole count (3). These parameters define functional equivalence for circuit breaker applications.

Q: Why does the substitute have a higher DC voltage rating?

A: The Phoenix Contact 2907623 is rated for 125V DC compared to the original 65V DC specification. This represents an expanded operational envelope that maintains full compatibility with applications designed for the lower voltage rating. The substitute performs within or exceeds all requirements of the original design.

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

A: The SCHURTER 4420.0242 is classified as obsolete, indicating discontinued production. The Phoenix Contact 2907623 maintains active production status, providing assured availability for replacement and new installations. This status difference is the primary driver for substitution consideration.

Q: Are there packaging differences between these components?

A: The SCHURTER unit packaging is unspecified in available documentation. The Phoenix Contact substitute is supplied in box packaging. Packaging format does not affect electrical or mechanical compatibility for DIN rail installation.

Q: Do both components meet the same regulatory requirements?

A: Both components are ROHS3 compliant and REACH unaffected. Both carry identical ECCN and HTSUS classifications, confirming equivalent regulatory standing for procurement and deployment.
