SCHURTER 4430.0705 Thermal Circuit Breaker Equivalent & Substitute Parts

Part Overview

The SCHURTER 4430.0705 is a thermal circuit breaker rated for 3A at 240V AC / 60V DC with rocker panel mount actuation and dual-pole configuration. This component is classified as Active product status and complies with international safety standards including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. The part is ROHS3 compliant and currently maintains 883 pieces in new original stock inventory.

Equivalent substitute parts are necessary when the primary part number becomes unavailable, when procurement lead times require alternative sourcing, or when design flexibility permits selection from multiple qualified part numbers within the same electrical and mechanical specification class.

Substitute Part Grouping Explanation

Substitution eligibility for thermal circuit breakers in this category is determined by strict equivalence across the following parameters:

Current Rating: 3A (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)
Manufacturer: SCHURTER Inc. (single source)

All substitute part numbers listed below meet these electrical and mechanical parameters without exception. Series designation (TA45 or TA35) does not restrict substitution eligibility when all electrical and mechanical parameters are identical.

Frequently Asked Questions (FAQ)

Q: Can I substitute 4435.0022 (TA35 series) for 4430.0705 (TA45 series)?

A: Yes. Both part numbers are electrically and mechanically equivalent. The series designation does not affect substitution eligibility when all electrical parameters (3A, 240V AC, 60V DC) and mechanical parameters (thermal breaker, panel mount, rocker actuator, 2-pole) are identical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute part numbers maintain ROHS3 compliance status and REACH unaffected classification.

Q: What is the difference between part numbers if they are all equivalent?

A: The part numbers represent different manufacturing batches or internal SCHURTER production variants. Electrical and mechanical specifications are identical across all listed part numbers. Differences are internal to SCHURTER manufacturing processes and do not affect circuit breaker performance or compatibility.

Q: Can I mix part numbers in the same application?

A: Yes. All substitute parts meet identical electrical and mechanical specifications and are suitable for direct substitution in applications designed for the 4430.0705.

Q: Which substitute part has the highest inventory availability?
