Engineering Selection Recommendations

All listed substitute parts are Active product status and ROHS3 compliant. Parts 4430.161, 4430.0572, 4430.1067, 4430.1068, and 4430.1805 carry approval certifications including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. These certifications confirm compliance with international safety standards for circuit protection devices. Selection between equivalent parts may be based on inventory availability and certification requirements specific to the application's regulatory jurisdiction.

Frequently Asked Questions (FAQ)

Q: Can all listed part numbers be used interchangeably with SCHURTER 4430.161?

A: Yes. All substitute parts maintain identical electrical ratings (20A, 240V AC, 60V DC), thermal breaker type, rocker actuator, dual-pole configuration, and panel mount design within the TA45 series. Mechanical and electrical compatibility is assured.

Q: What determines substitution eligibility for this circuit breaker?

A: Substitution is determined by matching current rating (20A), AC voltage rating (240V), DC voltage rating (60V), breaker type (thermal), actuator type (rocker), pole count (2), mounting method (panel mount), and series designation (TA45). All listed parts meet these criteria.

Q: Are there differences in approval certifications among the substitute parts?

A: Five parts (4430.161, 4430.0572, 4430.1067, 4430.1068, 4430.1805) include CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 certifications. The remaining parts are ROHS3 compliant and REACH unaffected but do not list these specific approvals. Selection should consider regulatory requirements for the intended application.

Q: Does packaging format affect substitution?

A: All parts are supplied in bulk packaging. Packaging format does not affect electrical or mechanical substitution capability.

Q: What is the inventory status of substitute parts?

A: Inventory ranges from 673 to 1098 pieces across all substitute part numbers. Current availability should be confirmed at time of procurement.
