Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 4420.0424 is determined by the following critical parameters:

• Current Rating: Must be 3A
• Mounting Type: Must be DIN Rail
• Breaker Type: Must be Thermal Magnetic
• Actuator Type: Must be Lever
• Number of Poles: Must be 3
• Voltage Compatibility: AC and DC voltage ratings must meet or exceed the original specification (277V AC minimum, 65V DC minimum)
• Regulatory Compliance: RoHS3 and REACH compliance maintained

The identified substitute parts meet these core electrical and mechanical criteria, enabling direct functional replacement in applications requiring the SCHURTER 4420.0424 specification.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 2907609 is an active product with ROHS3 compliance and REACH unaffected status. This part exceeds the voltage specifications of the original SCHURTER component (480V AC vs. 277V AC; 125V DC vs. 65V DC) while maintaining identical current rating, pole configuration, and mounting characteristics. The higher voltage rating provides operational margin in applications where the original specification is required.

Carlo Gavazzi GSB633PC3 is an active product with UL1077 approval and REACH unaffected status. This part also exceeds the AC voltage specification (480V AC vs. 277V AC) and maintains the 3A current rating, 3-pole configuration, and DIN rail mounting. DC voltage rating is not specified in available documentation.

Both substitute parts are currently in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete SCHURTER 4420.0424.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2907609 or Carlo Gavazzi GSB633PC3 directly replace the SCHURTER 4420.0424?

A: Both parts meet the core functional requirements: 3A current rating, 3-pole thermal magnetic breaker, lever actuation, and DIN rail mounting. The higher AC voltage ratings (480V vs. 277V) are compatible with applications designed for the original 277V specification.

Q: What is the significance of the higher voltage ratings in the substitute parts?

A: The substitute parts are rated for higher voltages (480V AC and 125V DC) than the original SCHURTER component (277V AC and 65V DC). This means they can operate safely in applications requiring the original specification without derating. The higher rating does not affect performance in lower-voltage applications.

Q: Are there packaging differences between these parts?

A: The SCHURTER 4420.0424 packaging is listed as "-" (not specified). Phoenix Contact 2907609 is supplied in Box packaging. Carlo Gavazzi GSB633PC3 is supplied in Box packaging. Packaging differences do not affect electrical or mechanical compatibility.

Q: What compliance certifications should I verify for my application?

A: The SCHURTER 4420.0424 is ROHS3 compliant and REACH unaffected. Phoenix Contact 2907609 maintains ROHS3 compliance and REACH unaffected status. Carlo Gavazzi GSB633PC3 is REACH unaffected and carries UL1077 approval. Verify that the selected substitute meets your specific regulatory requirements for your end application.

Q: Why is the SCHURTER 4420.0424 classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by SCHURTER Inc. The substitute parts listed are active products from established manufacturers, providing continuity for applications requiring this circuit breaker specification.
