Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 2907626 qualifies as a functional substitute for the SCHURTER 4420.0595 based on the following critical parameters:

• Breaker Type: Both are thermal magnetic circuit breakers
• Current Rating: Both rated at 1A
• Voltage Rating - AC: Both rated at 277V AC
• Mounting Type: Both mount on DIN rail
• Actuator Type: Both feature lever actuation
• Number of Poles: Both are single-pole (1P) configurations
• Voltage Rating - DC: The substitute is rated at 60V DC, which is within the operational envelope of the original 65V DC specification

The substitute maintains electrical and mechanical compatibility across all primary selection criteria for thermal magnetic circuit breaker applications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2907626 is the identified substitute for the obsolete SCHURTER 4420.0595. Both components meet identical regulatory compliance standards including CSA, EN, GB, IEC, and UL certifications applicable to thermal magnetic circuit breakers. The substitute maintains active product status, ensuring ongoing availability and supply chain continuity. Both components are ROHS3 compliant and REACH unaffected, satisfying environmental and regulatory requirements. The DC voltage rating differential (60V versus 65V) does not preclude substitution in applications where the original 65V specification was selected, as the substitute operates within the functional requirements of single-pole thermal magnetic protection at 1A and 277V AC.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2907626 directly replace the SCHURTER 4420.0595 in existing installations?

A: Yes. Both components share identical current rating (1A), AC voltage rating (277V), mounting type (DIN rail), actuator type (lever), and pole configuration (1P). The DC voltage rating of the substitute (60V) is compatible with applications designed for the original 65V specification.

Q: What is the significance of the product status difference between the two parts?

A: The SCHURTER 4420.0595 is classified as obsolete, meaning it is no longer manufactured or supported by the original supplier. The Phoenix Contact 2907626 maintains active status, ensuring continued availability, technical support, and supply chain reliability for new installations and replacements.

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

A: Both components are ROHS3 compliant and REACH unaffected. Both meet the same international standards for thermal magnetic circuit breakers. No compliance barriers exist for substitution.

Q: Does the packaging difference (Bulk versus Box) affect electrical or mechanical compatibility?

A: No. Packaging type is a logistics and inventory consideration only. It does not affect the electrical performance, mechanical fit, or functional compatibility of the circuit breaker in the application.

Q: What parameters must remain identical for substitution to be valid?

A: For thermal magnetic circuit breaker substitution, the following parameters must match: breaker type, current rating, AC voltage rating, mounting type, actuator type, and number of poles. The DC voltage rating may vary within operational limits.
