Substitute Part Grouping Explanation

Substitution within this product family is determined by strict parametric equivalence across all electrical and mechanical characteristics. All substitute parts listed maintain identical specifications for current rating (5A), voltage ratings (240V AC / 60V DC), breaker type (thermal), actuator configuration (rocker), pole count (2), and mounting method (panel mount). These parameters define the functional interchangeability of components within the TA45 series. Substitute parts are grouped as parametric equivalents based on matching all specified electrical and mechanical parameters, ensuring direct replacement capability without circuit redesign or mechanical modification.

Engineering Selection Recommendations

All listed substitute parts are Active product status components with ROHS3 compliance. Parts 4430.0586, 4430.1201, 4430.1353, 4430.1384, 4430.1564, 4430.1926, 4430.2297, and 4430.2303 carry CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 certifications. Part 4430.1856 and 4430.0977 are ROHS3 compliant with Active status. Selection among these parametric equivalents may be based on inventory availability, certification requirements for specific applications, and supply chain considerations. All parts maintain identical electrical performance and mechanical fit within the TA45 series thermal circuit breaker family.

Frequently Asked Questions (FAQ)

Q: Can all listed parts directly replace SCHURTER 4430.1856? A: Yes. All substitute parts are parametric equivalents with identical current rating (5A), voltage ratings (240V AC / 60V DC), breaker type (thermal), actuator type (rocker), pole count (2), and panel mount configuration. Direct replacement is supported without circuit modification.

Q: What determines substitution eligibility for this circuit breaker? A: Substitution is determined by matching all electrical parameters (5A current, 240V AC, 60V DC) and mechanical specifications (thermal breaker, rocker actuator, 2-pole, panel mount, TA45 series). Any deviation in these parameters disqualifies a part as a direct substitute.

Q: Are there differences in certifications among the substitute parts? A: Parts 4430.0586, 4430.1201, 4430.1353, 4430.1384, 4430.1564, 4430.1926, 4430.2297, and 4430.2303 carry CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 certifications. Parts 4430.1856 and 4430.0977 are ROHS3 compliant without these additional certifications listed. Application requirements may dictate certification selection.

Q: What is the inventory status of substitute parts? A: Inventory levels vary across the substitute family. Part 4430.2303 has the highest availability at 3604 pieces. Part 4430.0847 has the lowest at 803 pieces. All parts are listed as New Original In Stock.

Q: Are all parts in the same packaging format? A: All parts are supplied in Bulk packaging format consistent with the main part 4430.1856.
