Engineering Selection Recommendations

All listed substitute parts are active production components manufactured by SCHURTER Inc. and are ROHS3 compliant. Parts 4430.0586, 4430.1201, 4430.1353, 4430.1384, 4430.1564, 4430.1926, and 4430.2297 carry approval certifications including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. Selection between equivalent parts should be based on availability and supply chain requirements, as all parts meet identical electrical and mechanical specifications for the TA45 series 5A thermal circuit breaker application.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the 4430.2757?

A: Substitute parts must match all critical parameters: 5A current rating, 240V AC and 60V DC voltage ratings, thermal breaker type, panel mount configuration, rocker actuator, 2-pole design, and TA45 series designation. All listed parts meet these requirements.

Q: Are all substitute parts mechanically compatible with the original mounting?

A: Yes. All substitute parts feature identical panel mount configuration and rocker actuator design, ensuring direct mechanical compatibility in existing panel installations.

Q: What is the difference between parts with and without listed approval agencies?

A: Parts with CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 certifications carry additional regulatory approvals. Parts without these listed certifications remain ROHS3 compliant and suitable for applications where these specific certifications are not required.

Q: Can I mix substitute parts in the same application?

A: Yes. All substitute parts are electrically and mechanically equivalent and can be used interchangeably in applications requiring a 5A thermal circuit breaker rated for 240V AC and 60V DC with panel mount rocker actuation.

Q: What inventory levels are available for each substitute part?

A: Inventory varies by part number, ranging from 722 to 1518 units in stock. Part 4430.1201 has the highest current inventory at 1518 units.
