• Voltage Rating - DC: 60V (exact match required)
• Breaker Type: Thermal (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Actuator Type: Rocker (exact match required)
• Number of Poles: 2 (exact match required)
• Series: TA45 (same product family)
• Regulatory Compliance: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077

The identified substitute part 4430.1624 meets all electrical and mechanical parameters specified above, confirming functional and physical interchangeability within the TA45 series.

Parameter Comparison

Engineering Selection Recommendations

Both the SCHURTER 4430.1776 and 4430.1624 are Active status products within the TA45 series, maintaining identical electrical specifications and mechanical form factors. Both components satisfy the same regulatory framework including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 certifications. Both are ROHS3 compliant and REACH unaffected. Selection between these parts may be based on inventory availability and lead time considerations, as all functional and compliance parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 4430.1624 directly replace SCHURTER 4430.1776 in existing designs?

A: Yes. Both parts are identical in current rating (1.2A), voltage ratings (240V AC / 60V DC), breaker type (thermal), mounting configuration (panel mount rocker), pole count (2), and series designation (TA45). No circuit redesign or mechanical modification is required.

Q: Are there any compliance differences between these two part numbers?

A: No. Both parts maintain identical regulatory certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077), RoHS status (ROHS3 compliant), and REACH classification (unaffected).

Q: What parameters must match for a part to be considered a true substitute?

A: For thermal circuit breakers in the TA45 series, the following parameters must match exactly: current rating, AC voltage rating, DC voltage rating, breaker type, mounting type, actuator type, and pole count. Deviations in any of these parameters disqualify a part from substitution eligibility.

Q: Is packaging type a factor in substitution compatibility?

A: Packaging type (bulk, tape and reel, etc.) does not affect electrical or mechanical compatibility. It is a logistics consideration only and does not impact circuit performance or physical installation.

Q: What should be verified before implementing a substitute part in production?

A: Confirm that all electrical parameters (current, voltage ratings) and mechanical specifications (mounting type, actuator style, pole configuration) match the original design requirements. Verify that the substitute part maintains the same regulatory certifications required by your application.
