Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 4420.026 is determined by the following critical parameters:

• Current Rating: Must be 16A
• Voltage Rating - AC: Must be 277V
• Voltage Rating - DC: Must be 60V or higher (65V minimum preferred)
• Mounting Type: Must be DIN Rail
• Breaker Type: Must be Thermal Magnetic
• Actuator Type: Must be Lever
• Number of Poles: Must be 1
• Mechanical Compatibility: Form factor and terminal configuration must support direct replacement

The Phoenix Contact 2907639 meets these substitution criteria with equivalent electrical ratings and mechanical form factor, with the exception of a marginally lower DC voltage rating (60V versus 65V), which remains within acceptable tolerance for most industrial applications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2907639 is the identified equivalent substitute for the obsolete SCHURTER 4420.026. Both components share identical AC voltage ratings (277V), current ratings (16A), mounting configuration (DIN Rail), and mechanical actuation (lever-operated single pole). The DC voltage rating differential (60V versus 65V) represents a 5V reduction and does not preclude substitution in applications where the system DC voltage does not exceed 60V.

The Phoenix Contact 2907639 holds active product status with current manufacturing support, ensuring availability and supply chain continuity. Both components maintain ROHS3 compliance and equivalent regulatory approvals under IEC 60934 and UL standards, supporting direct replacement in existing installations and new designs requiring this specification class.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2907639 directly replace the SCHURTER 4420.026?

A: Yes. Both components are single-pole, 16A thermal magnetic circuit breakers with 277V AC ratings, lever actuation, and DIN rail mounting. The 60V DC rating of the Phoenix Contact part is suitable for replacement in systems operating at or below 60V DC.

Q: What is the significance of the DC voltage rating difference?

A: The SCHURTER 4420.026 is rated for 65V DC, while the Phoenix Contact 2907639 is rated for 60V DC. This 5V difference means the Phoenix Contact part is suitable for DC applications up to 60V. If your system operates above 60V DC, the original specification must be maintained or alternative parts evaluated.

Q: Why is the SCHURTER 4420.026 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Phoenix Contact 2907639 provides functional equivalence with active manufacturing status, ensuring long-term availability and support.

Q: Are there packaging differences between these parts?

A: The SCHURTER 4420.026 packaging is unspecified in available documentation. The Phoenix Contact 2907639 is supplied in box packaging. Verify packaging requirements for your procurement and logistics processes.

Q: Do both parts meet the same regulatory standards?

A: Both components comply with ROHS3 requirements and are approved under IEC 60934 and UL standards. The Phoenix Contact part carries REACH Affected status, while the SCHURTER part is REACH Unaffected. Verify REACH compliance requirements for your application and supply chain.
