Engineering Selection Recommendations

For applications currently using the obsolete 4430.3625, direct parametric equivalents within the TA45 series include 4430.0617 and 4430.0764, which maintain identical electrical and mechanical specifications. However, these parts also carry obsolete status.

For new designs or long-term supply chain continuity, active-status alternatives are available: 4430.1147, 4430.1158, 4430.1204, 4430.1962, 4430.2087, 4430.2226, and 4430.2487. All active substitutes maintain the required 240 V AC / 60 V DC dual-voltage rating, thermal breaker operation, panel mount configuration, rocker actuation, and dual-pole design.

Parts 4430.1204, 4430.2226, and 4430.2487 carry documented approval agency certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077), providing additional regulatory documentation for applications requiring formal compliance verification.

The MFR recommended part 4430.1051 is classified as a general AC/DC thermal circuit breaker with active status and REACH unaffected designation, though specific voltage and mounting parameters are not detailed in the provided data.

Frequently Asked Questions (FAQ)

Q: Can 4430.1051 directly replace 4430.3625?

A: 4430.1051 is designated as the MFR recommended substitute and carries active product status with REACH unaffected compliance. However, the provided data does not specify voltage ratings, mounting type, or pole configuration for 4430.1051. Confirmation of these parameters against your application requirements is necessary before selection.

Q: What is the difference between obsolete and active substitute parts?

A: Obsolete parts (4430.0617, 4430.0764) are no longer in active production but maintain identical specifications to 4430.3625. Active parts (4430.1147, 4430.1158, 4430.1204, 4430.1962, 4430.2087, 4430.2226, 4430.2487) are currently manufactured and represent the preferred choice for new installations and long-term supply assurance.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts carry ROHS3 compliance status, matching the original 4430.3625 specification.

Q: What is the significance of REACH Affected versus REACH Unaffected status?

A: The original 4430.3625 carries REACH Affected status. Active substitutes carry REACH Unaffected status, indicating updated regulatory compliance. This distinction may be relevant for applications subject to REACH regulation requirements.

Q: Do all substitutes support the same 240 V AC / 60 V DC voltage ratings?

A: All parametric equivalents (4430.0617, 4430.0764, 4430.1147, 4430.1158, 4430.1204, 4430.1962, 4430.2087, 4430.2226, 4430.2487) maintain the identical 240 V AC and 60 V DC voltage ratings required for direct substitution. The MFR recommended part 4430.1051 does not specify these parameters in the provided data.

Q: Which substitutes carry formal approval agency certifications?

A: Parts 4430.1204, 4430.2226, and 4430.2487 include documented certifications from CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. These certifications provide formal regulatory documentation for applications requiring compliance verification.
