Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 4430.2911 are grouped into two categories based on series designation:

TA45 Series Equivalents: Parts 4430.0423, 4430.0646, 4430.1631, 4430.2237, 4430.2269, and 4430.3661 are direct parametric equivalents within the same TA45 series. These parts share identical electrical specifications (8A, 240V AC, 60V DC), mechanical configuration (2-pole rocker panel mount), and regulatory compliance status.

TA35 Series Equivalents: Parts 4435.009, 4435.0272, 4435.0345, and 4435.0356 are parametric equivalents from the TA35 series. These parts maintain identical electrical ratings and mechanical form factor but represent an alternative series designation within the SCHURTER thermal breaker product line.

Substitution is valid when the following parameters match:

Current Rating: 8A
Voltage Rating - AC: 240V
Voltage Rating - DC: 60V
Breaker Type: Thermal
Mounting Type: Panel Mount
Actuator Type: Rocker
Number of Poles: 2

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance. Parts 4430.0646, 4430.1631, 4430.2237, 4430.2269, 4430.3661, 4435.009, and 4435.0272 carry documented approval certifications including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077, where specified in manufacturer data.

TA45 series parts (4430.0423, 4430.0646, 4430.1631, 4430.2237, 4430.2269, 4430.3661) maintain the same series designation as the primary part 4430.2911 and are preferred for direct replacement in existing designs. TA35 series parts (4435.009, 4435.0272, 4435.0345, 4435.0356) represent an alternative series option with identical electrical and mechanical specifications.

Selection between TA45 and TA35 series should be based on design documentation and PCB layout requirements, as series designation may indicate dimensional or mounting interface variations not specified in the provided parameters.

Frequently Asked Questions (FAQ)

Q: Can TA35 series parts replace TA45 series parts? A: TA35 and TA45 series parts share identical electrical ratings (8A, 240V AC, 60V DC), breaker type (thermal), mounting configuration (panel mount), and actuator type (rocker). Substitution is electrically valid. However, series designation may indicate design-specific differences. Consult original design documentation to confirm mechanical compatibility.

Q: What parameters must match for a valid substitution? A: Current rating (8A), voltage ratings (240V AC / 60V DC), breaker type (thermal), mounting type (panel mount), actuator type (rocker), and pole count (2) must all match. All listed parts meet these criteria.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All parts listed, including the primary part 4430.2911 and all substitutes, are ROHS3 compliant.

Q: What is the inventory status of substitute parts? A: Current inventory ranges from 677 to 1031 units across all substitute parts. Part 4430.3661 has the highest availability at 1018 units, while 4435.0356 has the lowest at 677 units.

Q: Do all substitute parts have the same regulatory approvals? A: Most substitute parts carry CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 certifications. Parts 4430.2911, 4430.0423, and 4435.0272 do not list specific approval agencies in the provided data. Consult manufacturer documentation for complete certification details.
