Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 4420.0434 is determined by the following critical parameters:

• Current Rating: Must be 1A
• 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 specifications (277V AC minimum, 65V DC minimum)

The identified substitute parts meet these core electrical and mechanical requirements, enabling direct functional replacement in applications originally designed for the SCHURTER 4420.0434.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 2907607 is the primary substitute option. This part maintains all critical electrical and mechanical parameters while offering higher voltage ratings (480V AC, 125V DC) that exceed the original specification. The component is currently in active production status with confirmed ROHS3 compliance and REACH affected designation, ensuring regulatory alignment and supply chain availability.

Carlo Gavazzi GSB633PC1 serves as a secondary substitute option. This part meets all mechanical requirements and current rating specifications with equivalent AC voltage rating (480V). The component carries UL1077 approval and is in active production status. DC voltage rating is not specified in available documentation, requiring verification for applications requiring DC operation.

Both substitute parts are available in active production status, contrasting with the obsolete status of the original SCHURTER component. Selection between these options should be based on specific application requirements, particularly regarding DC voltage operation and regulatory certification needs.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2907607 directly replace the SCHURTER 4420.0434?

A: Yes. Both components share identical current rating (1A), mounting type (DIN Rail), breaker type (thermal magnetic), actuator type (lever), and pole configuration (3-pole). The Phoenix Contact part has higher voltage ratings, which provides compatibility with the original 277V AC and 65V DC specifications.

Q: What is the primary difference between the substitute parts?

A: The Phoenix Contact 2907607 specifies both AC (480V) and DC (125V) voltage ratings. The Carlo Gavazzi GSB633PC1 specifies AC voltage (480V) with DC rating not documented. For applications requiring DC operation, the Phoenix Contact part provides explicit DC rating confirmation.

Q: Are there packaging differences between these parts?

A: Both substitute parts are supplied in box packaging. The original SCHURTER component packaging designation is not specified in available data.

Q: Do the substitute parts maintain RoHS compliance?

A: The Phoenix Contact 2907607 is ROHS3 compliant. The Carlo Gavazzi GSB633PC1 RoHS status is not specified in available documentation. For applications requiring RoHS compliance verification, the Phoenix Contact part provides explicit certification.

Q: Why is the original SCHURTER 4420.0434 marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. Substitute parts in active production status ensure continued availability for system maintenance and new implementations.
