Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original 4430.3823 specification. Parts 4430.0572, 4430.1067, 4430.1068, and 4430.161 include documented approval agency certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077), providing additional compliance documentation for applications requiring third-party validation.

Selection between equivalent parts should be based on inventory availability and specific approval requirements for the target application. All parts are functionally interchangeable within circuits designed for 20A thermal protection at 240V AC and 60V DC with panel mount rocker actuator configuration.

Frequently Asked Questions (FAQ)

Q: Can all listed part numbers be used interchangeably with 4430.3823?

A: Yes. All substitute parts maintain identical electrical ratings (20A, 240V AC, 60V DC), breaker type (thermal), mounting configuration (panel mount), and actuator style (rocker). They are parametrically equivalent within the TA45 series.

Q: What is the difference between parts with and without approval agency certifications?

A: Parts 4430.0572, 4430.1067, 4430.1068, and 4430.161 include documented certifications from CSA, EN, GB, IEC, and UL standards bodies. Parts without listed certifications remain ROHS3 and REACH compliant. Certification selection depends on application requirements and regional regulatory mandates.

Q: Are there differences in Moisture Sensitivity Level (MSL) between substitute parts?

A: Some parts list MSL as "Not Applicable" while others show "Vendor Undefined." These designations do not affect electrical or mechanical performance and do not impact substitutability for standard circuit breaker applications.

Q: What packaging format is used for these parts?

A: All parts are supplied in Bulk packaging format.

Q: How do I determine which substitute part to order?

A: Selection should be based on current inventory availability and any application-specific approval requirements. Verify that the selected part number meets your regional compliance standards before procurement.
