Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for thermal magnetic circuit breakers is determined by strict alignment of the following parameters:

• Current Rating: 15A (exact match required)
• Voltage Rating - AC: 277V (exact match required)
• Voltage Rating - DC: 60V–65V (acceptable tolerance range)
• 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 2907638 meets all substitution criteria with a DC voltage rating of 60V, which falls within the operational tolerance of the original 65V specification.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2907638 is the identified substitute for the obsolete SCHURTER 4420.0197. Both components share identical current ratings, AC voltage ratings, mounting configurations, and actuator types. The DC voltage rating difference of 5V (65V original versus 60V substitute) is within acceptable operational tolerance for thermal magnetic circuit breaker applications.

The substitute part carries active product status, ensuring ongoing availability and supply chain continuity. Both components maintain ROHS3 compliance, supporting environmental and regulatory requirements. Verification of specific approval certifications for the Phoenix Contact part against your system's regulatory requirements is necessary prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2907638 directly replace the SCHURTER 4420.0197?

A: Yes. Both components are single-pole thermal magnetic circuit breakers with identical 15A current ratings and 277V AC voltage ratings, mounted on DIN rail with lever actuation. The 5V difference in DC voltage rating (60V versus 65V) is within acceptable tolerance for this component category.

Q: Why is the DC voltage rating different between the two parts?

A: Manufacturers specify DC voltage ratings based on their design and testing parameters. A 60V DC rating is functionally compatible with applications designed for 65V DC operation within thermal magnetic circuit breaker specifications.

Q: What is the significance of the product status change from Obsolete to Active?

A: The substitute part is currently in active production and distribution, eliminating supply chain risk associated with the obsolete original component. This ensures long-term availability for maintenance and future orders.

Q: Are there packaging differences between these parts?

A: The SCHURTER part is specified with standard packaging, while the Phoenix Contact part is packaged in boxes. Both are suitable for DIN rail installation and do not require special handling considerations.

Q: Should I verify regulatory approvals before implementation?

A: Confirmation of applicable regulatory certifications for your specific application is recommended. The original part lists multiple approvals; verification that the substitute meets your system's certification requirements is a standard engineering practice.
