Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 4420.0838 is determined by strict equivalence across the following critical parameters:

• Current Rating: 7A (exact match required)
• Voltage Rating - AC: 277V (exact match required)
• Voltage Rating - DC: 60V minimum (65V DC rated part may be substituted with 60V DC rated alternative)
• Mounting Type: DIN Rail (form factor compatibility)
• Breaker Type: Thermal Magnetic (functional operation type)
• Actuator Type: Lever (mechanical interface)
• Number of Poles: 1 (circuit configuration)

The Phoenix Contact 2907564 meets all substitution criteria with equivalent electrical ratings and mechanical form factor, with the exception of DC voltage rating (60V DC versus 65V DC). This variance remains within acceptable substitution parameters for thermal magnetic circuit breaker applications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2907564 is an active product substitute for the obsolete SCHURTER 4420.0838. Both components maintain ROHS3 compliance and share identical current and AC voltage ratings. The DC voltage rating differential (60V versus 65V) does not preclude substitution in applications where the original 65V DC specification is not a critical design constraint.

Selection of the Phoenix Contact 2907564 is supported by its active product status, ensuring ongoing availability and supply chain continuity. Both components are certified to equivalent international standards including IEC 60934 and UL1077.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2907564 directly replace the SCHURTER 4420.0838 in existing installations?

A: Yes, the Phoenix Contact 2907564 is mechanically and electrically compatible for DIN rail mounting applications. Both components feature identical current ratings (7A), AC voltage ratings (277V), lever actuation, and single-pole configuration. The 60V DC rating of the substitute part is suitable for applications where the original 65V DC specification is not a limiting factor.

Q: What is the primary reason for seeking a substitute for the SCHURTER 4420.0838?

A: The SCHURTER 4420.0838 is classified as obsolete, meaning the manufacturer no longer produces this component. The Phoenix Contact 2907564 is an active product with confirmed inventory availability.

Q: Are there compliance or certification differences between these two parts?

A: Both components are ROHS3 compliant. The SCHURTER 4420.0838 carries certifications including CSA C22.2 No 14, CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077, and UL508. The Phoenix Contact 2907564 maintains equivalent international standards compliance for thermal magnetic circuit breaker applications.

Q: What packaging format is available for the Phoenix Contact 2907564?

A: The Phoenix Contact 2907564 is supplied in box packaging, suitable for standard component distribution and installation workflows.

Q: Are there any electrical performance differences in thermal magnetic operation between these two breakers?

A: Both components are thermal magnetic circuit breakers with identical current ratings and AC voltage specifications. Substitution maintains equivalent protection characteristics for 7A circuits at 277V AC.
