Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 4430.1133 is determined by strict equivalence across the following parameters:

Current Rating: 1A (exact match required)
Voltage Rating - AC: 240V (exact match required)
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)
Product Status: Active (required for current applications)
RoHS Compliance: ROHS3 Compliant (required for regulatory alignment)

All substitute parts listed below meet these criteria and are drawn from the SCHURTER TA45 and TA35 series families. Series designation (TA45 or TA35) does not restrict substitution when all electrical and mechanical parameters are identical.

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the SCHURTER 4430.1133 and are suitable for direct replacement in applications requiring 1A thermal circuit protection at 240V AC / 60V DC with rocker panel mount configuration.

Selection among equivalent parts may be based on:

Inventory availability across part numbers
Approval agency certifications where specified (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077 listed for parts 4430.1143, 4430.1273, 4430.2411, and 4430.2862)
Moisture Sensitivity Level designation where applicable
Supply chain lead time and logistics considerations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with current manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can part 4435.0008 or 4435.0465 (TA35 series) be used as direct replacements for the 4430.1133 (TA45 series)?

A: Yes. Series designation does not restrict substitution when all electrical and mechanical parameters are identical. Both TA35 and TA45 series parts listed maintain 1A current rating, 240V AC / 60V DC voltage ratings, thermal breaker type, panel mount configuration, rocker actuation, and dual-pole design.

Q: What parameters must remain constant for substitution eligibility?

A: Current rating (1A), voltage ratings (240V AC / 60V DC), breaker type (thermal), mounting type (panel mount), actuator type (rocker), and number of poles (2) must be identical. All listed parts meet these requirements.

Q: Are there differences in approval certifications among the substitute parts?

A: Parts 4430.1143, 4430.1273, 4430.2411, and 4430.2862 carry explicit approval agency certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077). Other parts do not list specific certifications in the provided data. Verify certification requirements for your application before selection.

Q: Does Moisture Sensitivity Level (MSL) affect substitution?

A: MSL is not a substitution-limiting parameter for these thermal circuit breakers. Part 4430.131 lists MSL as Vendor Undefined; all other parts list MSL as Not Applicable. This does not restrict interchangeability.

Q: What is the inventory status of substitute parts?

A: All substitute parts are listed as New Original In Stock with quantities ranging from 676 to 1447 pieces, ensuring availability for procurement.
