Selection among these alternatives may be based on inventory availability and supply chain considerations. All parts maintain active production status and full ROHS3 compliance. The following certifications apply uniformly across all equivalent parts: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. No performance differentiation exists between the main part and substitutes based on the provided specifications.

Frequently Asked Questions (FAQ)

Q: Can 4430.0407 replace 4430.0573 directly? A: Yes. Both parts are identical in current rating (15A), voltage specifications (240V AC / 60V DC), breaker type (thermal), mounting configuration (panel mount rocker), pole count (2), and regulatory certifications. Direct one-to-one substitution is valid.

Q: Are all substitute parts certified to the same standards? A: All substitute parts listed carry certification to CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. Certification status is uniform across the substitution group.

Q: What determines if a part is a valid substitute? A: Substitution validity is determined by matching current rating (15A), AC voltage (240V), DC voltage (60V), breaker type (thermal), mounting type (panel mount), actuator type (rocker), pole count (2), and series designation (TA45). All listed parts meet these criteria.

Q: Is there a difference in RoHS compliance between parts? A: No. All parts in this substitution group are ROHS3 compliant. RoHS status is uniform.

Q: Can I use these parts interchangeably in production? A: Yes. All substitute parts are parametric equivalents with identical electrical ratings, mechanical dimensions for panel mounting, and regulatory approvals.
