Engineering Selection Recommendations

All listed substitute parts are active production components with ROHS3 compliance and REACH unaffected status, matching the regulatory posture of the primary part 4430.2802. Parts 4430.0572, 4430.1067, and 4430.1068 carry additional approval certifications including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077, providing expanded international standards coverage for applications requiring these certifications.

Selection among substitutes should be based on inventory availability and specific certification requirements for the target application. All parts are functionally equivalent for 20A thermal circuit protection at 240V AC and 60V DC in panel mount configurations.

Frequently Asked Questions (FAQ)

Q: Are all listed parts direct replacements for the SCHURTER 4430.2802?

A: Yes. All substitute parts share identical electrical ratings (20A, 240V AC, 60V DC), mechanical configuration (panel mount, rocker actuator, 2-pole), and functional classification (thermal breaker, TA45 series). They are electrically and mechanically interchangeable.

Q: What determines if a part can substitute for the 4430.2802?

A: Substitution is based on matching current rating, AC and DC voltage ratings, breaker type, mounting configuration, actuator type, and pole count. All listed parts meet these criteria.

Q: Do the substitute parts have different certifications?

A: Parts 4430.0572, 4430.1067, and 4430.1068 include additional international approvals (CSA, EN, GB, IEC, UL standards). Other substitutes maintain baseline ROHS3 and REACH compliance. Selection should account for certification requirements in the target application.

Q: Is there a difference in packaging or inventory status?

A: All parts are supplied in bulk packaging with active production status. Inventory quantities vary; refer to the parameter comparison table for current stock levels.

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

A: Yes, provided the application requires 20A thermal protection at 240V AC and 60V DC with panel mount rocker actuator configuration. No design modifications are necessary for direct substitution.
