Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for thermal magnetic circuit breakers is determined by strict equivalence across the following parameters:

• Current Rating: 5A (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 2907630 meets all substitution criteria with a DC voltage rating of 60V, which is within the operational tolerance for DC-rated circuit breakers in this category.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2907630 is the qualified substitute for the obsolete SCHURTER 4420.0314. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment in replacement applications. The Phoenix Contact part carries active product status, providing supply chain continuity and technical support availability. The 5V DC voltage rating differential (60V versus 65V) does not preclude substitution in standard industrial control applications where 277V AC and low-voltage DC protection are required.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2907630 directly replace the SCHURTER 4420.0314 in existing installations?

A: Yes. Both components share identical current ratings (5A), AC voltage ratings (277V), mounting configuration (DIN rail), actuation method (lever), and pole count (1). The 5V DC voltage rating difference is within acceptable tolerance for thermal magnetic circuit breaker applications.

Q: What is the significance of the obsolete status of the SCHURTER part?

A: Obsolete status indicates the SCHURTER 4420.0314 is no longer manufactured or supported by the original supplier. The Phoenix Contact 2907630 maintains active product status, ensuring availability, technical documentation, and manufacturer support for new installations or replacements.

Q: Are there any compliance differences between these two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Regulatory compliance is equivalent for industrial control applications.

Q: Does the packaging difference affect substitution?

A: Packaging format (box versus standard) does not affect electrical or mechanical compatibility. Packaging is a logistics consideration and does not impact functional substitution.

Q: What certifications apply to both parts?

A: The SCHURTER 4420.0314 carries certifications including CSA C22.2 No 14, CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077, and UL508. Verification of Phoenix Contact 2907630 certification alignment with specific application requirements is recommended during design review.
