Key Parameters

Substitute Part Grouping Explanation

Substitution for the SCHURTER 4420.0692 is determined by the following critical parameters that must match or be compatible with the original specification:

• Current Rating: 4A (exact match required)
• Voltage Rating - AC: 277V (exact match required)
• 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)
• Voltage Rating - DC: 65V or higher (acceptable if equal or greater)

The identified substitute parts meet these core electrical and mechanical parameters, enabling direct functional replacement in applications originally designed for the SCHURTER 4420.0692.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are classified as active products, ensuring ongoing availability and manufacturer support. The Altech 1C4UL carries cULus and UL489 certifications, while the Phoenix Contact 2907561 maintains ROHS3 compliance with active product status. The Phoenix Contact 2907561 specifies a 60V DC rating, which is marginally lower than the original 65V DC specification; this part remains functionally compatible for applications where the DC voltage requirement does not exceed 60V. The Altech 1C4UL does not specify a DC voltage rating in the provided data, requiring verification against application requirements before selection.

Frequently Asked Questions (FAQ)

Q: Can the Altech 1C4UL be used as a direct replacement for the SCHURTER 4420.0692?

A: The Altech 1C4UL matches all critical parameters: 4A current rating, 277V AC, DIN rail mounting, thermal magnetic operation, lever actuation, and single-pole configuration. However, the DC voltage rating is not specified in the available data. Confirmation of DC voltage compatibility with your application is necessary before implementation.

Q: What is the difference between the Phoenix Contact 2907561 and the original SCHURTER part?

A: The Phoenix Contact 2907561 is functionally equivalent across all specified parameters except DC voltage rating. The original SCHURTER 4420.0692 is rated for 65V DC, while the Phoenix Contact part is rated for 60V DC. This part is suitable for applications where the DC voltage requirement does not exceed 60V.

Q: Why is the SCHURTER 4420.0692 listed as obsolete?

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

Q: Are all substitute parts RoHS3 compliant?

A: Yes, both substitute parts are ROHS3 compliant, matching the environmental compliance status of the original SCHURTER 4420.0692.

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

A: The Altech 1C4UL carries CE, cULus, and UL489 certifications. The Phoenix Contact 2907561 carries certifications as specified by the manufacturer. Verify that the selected substitute meets the approval agency requirements for your application.
