Engineering Selection Recommendations

All listed substitute parts are active products manufactured by SCHURTER Inc. within the TA45 series. Each part maintains full compliance with regulatory standards including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 certifications where specified. All parts are ROHS3 compliant and carry REACH Unaffected status.

Selection among equivalent parts may be based on inventory availability and lead time considerations. Parts 4430.1892 (1268 Pcs), 4430.0778 (1193 Pcs), and 4430.0413 (1180 Pcs) offer the highest stock levels. All substitutes are electrically and mechanically interchangeable with the original 4430.1849 specification.

Frequently Asked Questions (FAQ)

Q: Can I substitute any of these part numbers for the original 4430.1849?

A: Yes. All listed parts are parametric equivalents with identical current ratings (10A), voltage ratings (240V AC / 60V DC), breaker type (thermal), mounting configuration (panel mount rocker), pole count (2), and series designation (TA45). Direct substitution is valid.

Q: What determines if a part is a valid substitute?

A: Substitution validity is determined by matching the following parameters: current rating, AC and DC voltage ratings, breaker type, mounting type, actuator type, number of poles, and series. All listed parts meet these criteria.

Q: Are there differences in regulatory compliance between substitute parts?

A: All substitute parts carry ROHS3 compliance and REACH Unaffected status. Most parts list approval by CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. Compliance documentation should be verified for specific application requirements.

Q: Does packaging differ between part numbers?

A: All parts are supplied in bulk packaging. Inventory quantities vary by part number but do not affect electrical or mechanical compatibility.

Q: Can I mix different part numbers in the same application?

A: Yes. Since all parts are parametric equivalents with identical electrical and mechanical specifications, they can be used interchangeably within the same circuit or system design.
