SCHURTER 4430.2863 Circuit Breaker Thermal 15A 240VAC 60VDC Equivalent & Substitute Parts

Part Overview

The SCHURTER 4430.2863 is a thermal circuit breaker rated for 15A at 240V AC and 60V DC, designed for panel mount applications with rocker actuator control. This two-pole breaker is classified as Active product status and complies with ROHS3 and REACH regulations. Substitute parts become necessary when the primary part number reaches end-of-life status, inventory depletion, or when design revisions require alternative configurations within the same electrical and mechanical specifications.

Engineering Selection Recommendations

All listed substitute parts are Active product status and maintain full ROHS3 compliance and REACH unaffected status. Selection among substitute parts should be based on inventory availability and lead time requirements. Parts with higher inventory levels (4430.1089 with 2961 pcs, 4430.1328 with 1295 pcs, and 4430.1402 with 1074 pcs) offer improved procurement reliability. All substitute parts are manufactured by SCHURTER Inc. within the TA45 series and are electrically and mechanically interchangeable with the primary part 4430.2863.

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts electrically interchangeable with 4430.2863?

A: Yes. All substitute parts maintain identical current rating (15A), voltage ratings (240V AC / 60V DC), breaker type (thermal), and pole configuration (2-pole). They are direct electrical equivalents.

Q: What determines if a part can substitute for 4430.2863?

A: Substitution is determined by matching the following parameters: 15A current rating, 240V AC voltage rating, 60V DC voltage rating, thermal breaker type, panel mount configuration, rocker actuator, 2-pole design, and TA45 series classification. All listed parts meet these criteria.

Q: Do all substitute parts have the same mechanical mounting footprint?

A: Yes. All substitute parts share identical mounting type (panel mount), actuator type (rocker), and series designation (TA45), ensuring mechanical compatibility with existing panel designs.

Q: Are there compliance differences between the main part and substitutes?

A: All parts maintain ROHS3 compliance and REACH unaffected status. Some substitute parts include documented approval agencies (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077), which represent additional certifications and do not affect substitution eligibility.

Q: Which substitute part has the best inventory availability?

A: Part number 4430.1089 has the highest inventory level at 2961 pieces, followed by 4430.1328 at 1295 pieces and 4430.1402 at 1074 pieces.

Q: Can I use these substitutes in new designs?
