Engineering Selection Recommendations

All listed substitute parts are classified as Active product status and maintain ROHS3 compliance. Parts 4430.3099, 4430.0572, 4430.1067, 4430.1068, and 4430.161 carry full regulatory approval certifications including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. These certifications confirm compliance with international circuit protection standards. Remaining substitute parts (4430.0035, 4430.0038, 4430.0978, 4430.0988, 4430.1629, 4430.1789) maintain ROHS3 compliance and REACH Unaffected status without documented approval agency certifications in the provided data. Selection between parts should be based on certification requirements specific to the application and regulatory jurisdiction.

Frequently Asked Questions (FAQ)

Q: Are all listed parts direct substitutes for SCHURTER 4430.3099?

A: Yes. All parts listed maintain identical electrical ratings (20A, 240V AC, 60V DC), thermal breaker type, 2-pole rocker panel mount configuration, and TA45 series designation. They are parametrically equivalent and functionally interchangeable.

Q: What determines if a part can substitute for the 4430.3099?

A: Substitution is determined by exact matching of current rating (20A), AC voltage (240V), DC voltage (60V), breaker type (thermal), mounting configuration (panel mount rocker), pole count (2), and series designation (TA45). Any deviation in these parameters disqualifies a part from substitution.

Q: Do all substitute parts have the same regulatory certifications?

A: No. Parts 4430.3099, 4430.0572, 4430.1067, 4430.1068, and 4430.161 carry CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 certifications. Other substitute parts maintain ROHS3 compliance and REACH Unaffected status. Verify certification requirements for your specific application before selection.

Q: What is the difference between parts with and without listed approval agencies?

A: Parts with documented approval agencies have undergone formal compliance testing and certification to international standards. Parts without listed certifications in the provided data may still meet equivalent standards but lack documented certification records in this reference. Consult SCHURTER technical documentation for complete certification details.

Q: Can I use any substitute part interchangeably in my circuit?

A: Yes, provided your application does not mandate specific regulatory certifications. All substitute parts are parametrically equivalent. If your design or regulatory environment requires specific certifications (CSA, UL, EN, IEC, GB), select only parts carrying those certifications.

Q: Are there inventory considerations when selecting a substitute?

A: Inventory levels vary across substitute parts, ranging from 673 to 1098 pieces in stock. Availability may influence selection timing but does not affect technical interchangeability.
