Frequently Asked Questions (FAQ)

Q: Can SCHURTER 4430.107 be used as a direct replacement for SCHURTER 4430.287?

A: Yes. The 4430.107 is a parametric equivalent with identical electrical ratings (20A, 240VAC, 60VDC), breaker type (thermal), mounting configuration (panel mount rocker), pole count (2), illumination (red at 110V nominal), and all regulatory certifications. Both parts are from the TA45 series and maintain active product status.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution requires exact matching across current rating (20A), AC voltage (240V), DC voltage (60V), breaker type (thermal), mounting type (panel mount), actuator type (rocker), pole count (2), illumination color (red), illumination voltage (110V nominal), series designation (TA45), and all regulatory approvals (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077).

Q: Are there any differences in packaging or inventory status between these parts?

A: Both parts are supplied in bulk packaging. SCHURTER 4430.287 has 1150 pieces in stock, while SCHURTER 4430.107 has 1065 pieces in stock. Packaging format is identical.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 4430.287 and 4430.107 carry identical certifications: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. Both are ROHS3 compliant.

Q: What is the functional purpose of the red illumination feature?

A: The red illumination at 110V nominal voltage provides visual indication of breaker status on the panel mount rocker actuator, enabling operators to quickly identify breaker state in industrial control applications.
