Frequently Asked Questions (FAQ)

Q: Can any of these substitute parts be used interchangeably with SCHURTER 4430.1121?

A: Yes. All listed substitute parts maintain identical electrical ratings (6A, 240V AC, 60V DC), breaker type (thermal), mounting configuration (panel mount rocker), pole count (2), series designation (TA45), and regulatory compliance. Direct substitution is supported based on parametric equivalence.

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

A: Substitution eligibility requires exact matching of current rating, voltage ratings (both AC and DC), breaker type, mounting type, actuator type, pole count, series, manufacturer, and regulatory approvals. All listed parts meet these criteria.

Q: Are there differences in packaging or form factor among these parts?

A: All substitute parts are packaged in bulk and maintain identical panel mount rocker configurations. No form factor differences exist among the listed equivalents.

Q: Do all substitute parts carry the same regulatory certifications?

A: Yes. All parts comply with CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. All are ROHS3 compliant and REACH unaffected.

Q: Which substitute part should be selected based on availability?

A: Part selection may be based on inventory levels. Part 4430.0991 offers the highest stock at 1026 pieces, followed by 4430.3552 at 1006 pieces. All parts are equally qualified for substitution.

Q: Are there any electrical performance differences between the main part and substitutes?

A: No. All parts are rated identically at 6A thermal protection for 240V AC and 60V DC operation. Electrical performance characteristics are equivalent across all listed part numbers.
