Parameter Comparison

Engineering Selection Recommendations

Both the 4430.1944 and 4430.2084 are active production components with ROHS3 compliance and REACH unaffected status. The 4430.2084 carries additional approval agency certifications including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. Selection between these parts should be based on regional regulatory requirements and specific application certifications. Where multi-regional compliance is required, the 4430.2084 with its documented approval agencies may be the preferred choice. Both parts are electrically and mechanically interchangeable for 20A thermal circuit breaker applications at 240V AC and 60V DC.

Frequently Asked Questions (FAQ)

Q: Are the 4430.1944 and 4430.2084 electrically interchangeable? A: Yes. Both parts have identical current ratings (20A), voltage ratings (240V AC, 60V DC), breaker type (thermal), and all other electrical specifications. They are direct parametric equivalents.

Q: What is the difference between these two part numbers? A: The primary difference is that the 4430.2084 includes documented approval agency certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077), while the 4430.1944 does not list specific certifications in the provided data.

Q: Can I use 4430.2084 as a replacement for 4430.1944 in existing designs? A: Yes, provided the application does not have specific part number requirements. The mechanical and electrical specifications are identical, and both are panel mount rocker actuator thermal breakers with 2 poles and orange illumination.

Q: Are there any packaging differences? A: Both parts are supplied in bulk packaging. No packaging format differences are specified in the technical data.

Q: Which part should I select for new designs? A: Selection should be based on regional compliance requirements. The 4430.2084 with its documented approval agencies is suitable for applications requiring multi-regional certifications. The 4430.1944 is suitable where specific certifications are not mandated.
