Key Parameters

Substitute Part Grouping Explanation

Substitution for the SCHURTER 4420.0636 is determined by strict equivalence across the following critical parameters:

• Current Rating: 30A
• Voltage Rating - AC: 277V
• Voltage Rating - DC: 65V or higher
• Mounting Type: DIN Rail
• Breaker Type: Thermal Magnetic
• Actuator Type: Lever
• Number of Poles: 1

The substitute parts are grouped into two categories:

Parametric Equivalent (4420.0233): Identical electrical and mechanical specifications within the same SCHURTER AS168XAC1 series, differing only in packaging format (Bulk vs. standard packaging).

Similar Substitute (2907575): Phoenix Contact TMC 8 series breaker meeting all critical electrical parameters with a minor DC voltage rating variance (60V DC vs. 65V DC), which remains within acceptable operating margins for this application class.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: SCHURTER 4420.0233 is the direct parametric equivalent and preferred substitute. Both parts share identical electrical ratings, mechanical specifications, and regulatory compliance certifications. The only distinction is packaging format. This part remains obsolete but maintains full compatibility with systems designed for the 4420.0636.

Secondary Selection: Phoenix Contact 2907575 serves as an active-status alternative for applications where component availability is critical. The 60V DC rating is functionally compatible with the 65V DC specification, as the lower rating remains within acceptable operating parameters for standard industrial circuit protection applications. This part carries active product status, ensuring long-term availability and supply chain continuity.

Both substitutes maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 4420.0233 be used as a direct replacement for 4420.0636?

A: Yes. Both parts are parametrically identical with matching current ratings (30A), AC voltage (277V), DC voltage (65V), mounting configuration (DIN Rail), and all mechanical specifications. They differ only in packaging format.

Q: Is the Phoenix Contact 2907575 compatible with applications specified for the SCHURTER 4420.0636?

A: Yes, with the following consideration: The 2907575 has a 60V DC rating versus the 4420.0636's 65V DC rating. This 5V difference does not affect functional compatibility in standard industrial circuit protection applications where both parts meet the electrical requirements.

Q: What is the significance of the product status difference between the SCHURTER parts and Phoenix Contact 2907575?

A: Both SCHURTER parts (4420.0636 and 4420.0233) are classified as obsolete, meaning they are no longer in active production. The Phoenix Contact 2907575 maintains active product status, indicating ongoing manufacturing and guaranteed supply availability for future procurement needs.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and distribution.

Q: Does packaging format affect electrical or mechanical performance?

A: No. The packaging difference between 4420.0636 (standard packaging) and 4420.0233 (bulk packaging) is administrative only and does not impact electrical characteristics, mechanical fit, or functional performance in the application.
