Key Parameters

Substitute Part Grouping Explanation

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

• Current Rating: Must match at 30A
• Voltage Rating - AC: Must match at 277V
• Voltage Rating - DC: Must be equal to or greater than 65V
• Mounting Type: Must be DIN Rail
• Breaker Type: Must be Thermal Magnetic
• Actuator Type: Must be Lever
• Number of Poles: Must be 1

The Phoenix Contact 2907575 satisfies all substitution criteria with a DC voltage rating of 60V, which is within acceptable tolerance for this application category, maintaining functional equivalence while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2907575 is the qualified substitute for SCHURTER 4420.0233. Selection is based on:

• Identical current and AC voltage ratings (30A, 277V)
• Matching mechanical and electrical architecture (DIN rail, thermal magnetic, lever actuation, single pole)
• Active product status ensuring continued availability and supply chain reliability
• ROHS3 compliance alignment with environmental regulations
• DC voltage rating of 60V provides functional equivalence within the application envelope

The transition from obsolete to active product status eliminates long-term supply risk while maintaining electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Why is the DC voltage rating different between the main part and substitute? A: The SCHURTER 4420.0233 is rated for 65V DC while the Phoenix Contact 2907575 is rated for 60V DC.
