Substitute Part Grouping Explanation

All substitute parts listed maintain identical electrical and mechanical parameters to the main part 4430.3426. Substitution eligibility is determined by the following criteria:

Current Rating: 20A (exact match required)
Voltage Rating AC: 240V (exact match required)
Voltage Rating DC: 60V (exact match required)
Breaker Type: Thermal (exact match required)
Mounting Type: Panel Mount (exact match required)
Actuator Type: Rocker (exact match required)
Number of Poles: 2 (exact match required)
Series: TA45 (exact match required)
Packaging: Bulk (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)

All substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with part 4430.3426.

Engineering Selection Recommendations

All listed substitute parts are Active product status and maintain full compliance with international safety certifications. Parts 4430.3426, 4430.0572, 4430.1067, 4430.1068, and 4430.161 carry explicit approval agency documentation for CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. Parts 4430.0035, 4430.0038, 4430.0978, 4430.0988, 4430.1629, and 4430.1789 maintain ROHS3 compliance and REACH Unaffected status without documented approval agency notation in the provided data.

Selection between equivalent parts may be based on inventory availability and supply chain considerations. All parts are packaged in Bulk format and are suitable for direct substitution in applications requiring a 20A thermal circuit breaker with 240V AC and 60V DC ratings in a rocker-actuated panel mount configuration.

Frequently Asked Questions (FAQ)

Q: Are all listed part numbers electrically interchangeable with 4430.3426?

A: Yes. All substitute parts maintain identical current rating (20A), voltage ratings (240V AC, 60V DC), breaker type (thermal), mounting configuration (panel mount rocker), and pole count (2). They are electrically and mechanically interchangeable.

Q: What determines if a part can substitute for 4430.3426?

A: Substitution requires exact matching of current rating, AC voltage rating, DC voltage rating, breaker type, mounting type, actuator type, number of poles, series designation, and RoHS compliance status. All listed parts meet these criteria.

Q: Do all substitute parts have the same certifications as 4430.3426?

A: Parts 4430.3426, 4430.0572, 4430.1067, 4430.1068, and 4430.161 carry explicit approval agency certifications. All parts maintain ROHS3 compliance and REACH Unaffected status. Consult specific certification documentation for application-critical requirements.

Q: Can I use these parts interchangeably in existing designs?

A: Yes, provided the design specifies only the electrical and mechanical parameters listed in the Key Parameters table. No design modifications are required for substitution between any of these part numbers.

Q: What is the difference between these part numbers if they are all equivalent?

A: The part numbers represent different manufacturing batches, design revisions, or internal SCHURTER designations. From an electrical and mechanical standpoint, they are functionally identical for the specified application parameters.

Q: Are there any packaging differences between substitute parts?

A: All substitute parts are supplied in Bulk packaging. No alternative packaging formats are listed in the provided data.
