SCHURTER 4430.1967 Thermal Circuit Breaker Equivalent & Substitute Parts

Part Overview

The SCHURTER 4430.1967 is an active thermal circuit breaker rated for 2A at 240V AC / 60V DC with rocker panel mount actuation. This TA45 series component is designed for overcurrent protection in dual-pole configurations. Substitute parts are necessary when the primary part number becomes unavailable or when design revisions require alternative manufacturing sources while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 4430.1967 is determined by strict equivalence across the following parameters:

Current Rating: 2A (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. (same manufacturer)
Product Status: Active (current production)
RoHS Compliance: ROHS3 Compliant (regulatory equivalence)

All substitute parts listed maintain identical electrical performance and mechanical form factor. Series designation (TA45 or TA35) does not restrict substitution when all electrical and mechanical parameters match.

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical equivalence to the SCHURTER 4430.1967. Selection among available alternatives should be based on:

Inventory Availability: Part 4430.2302 offers the highest stock level at 1132 units, followed by 4430.3743 at 1065 units. These options provide supply chain continuity for high-volume applications.

Regulatory Compliance: All substitute parts carry identical ROHS3 compliance and meet the same approval standards (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077 where specified). Parts 4430.2569, 4430.3743, 4435.0306, and 4435.0466 do not list approval agency certifications in available data but maintain ROHS3 and REACH compliance.

Series Consistency: TA45 series parts (4430.004, 4430.2296, 4430.2302, 4430.2451, 4430.2569, 4430.309, 4430.3171, 4430.3743) are functionally identical to the primary part. TA35 series parts (4435.0306, 4435.0466) are electrically equivalent but represent an alternative mechanical platform within the same manufacturer's thermal breaker portfolio.

Frequently Asked Questions (FAQ)

Q: Can I substitute 4435.0306 or 4435.0466 (TA35 series) for the original 4430.1967 (TA45 series)?

A: Yes. Both TA35 and TA45 series parts meet all specified electrical parameters: 2A current rating, 240V AC / 60V DC voltage ratings, thermal breaker type, rocker actuation, dual-pole configuration, and panel mount form factor. Series designation does not restrict substitution when electrical and mechanical specifications are identical.

Q: What parameters must match exactly for a part to be considered a true substitute?

A: Current rating (2A), voltage ratings (240V AC and 60V DC), breaker type (thermal), mounting type (panel mount), actuator type (rocker), and pole count (2) must all match exactly. All listed parts meet these criteria.

Q: Are there any compliance differences between substitute parts?

A: All substitute parts are ROHS3 compliant and REACH unaffected. Approval agency certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077) are specified for most parts. Verify specific certification requirements for your application before selection.

Q: Does packaging affect substitution eligibility?

A: No. All parts are supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Which substitute part offers the best inventory position?

A: Part 4430.2302 provides the highest current stock at 1132 units, making it the optimal choice for applications requiring immediate availability or high-volume procurement.
