SCHURTER 4435.0283 Thermal Circuit Breaker Equivalent & Substitute Parts

Part Overview

The SCHURTER 4435.0283 is an active thermal circuit breaker rated for 3A at 240V AC / 60V DC with rocker panel mount actuation and dual-pole configuration. This component is designed for overcurrent protection in AC and DC applications requiring compact, reliable switching. Equivalent and substitute parts within the SCHURTER TA35 and TA45 series maintain identical electrical and mechanical specifications, enabling direct replacement in applications where component availability or inventory requirements necessitate alternative part numbers.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: current rating (3A), voltage ratings (240V AC / 60V DC), breaker type (thermal), mounting configuration (panel mount rocker), pole count (2), and regulatory compliance (ROHS3). All substitute parts listed maintain these specifications without deviation. Series designation (TA35 or TA45) does not restrict substitution, as both series share identical electrical and mechanical interfaces for this rating class. Parts are grouped by availability and certification status to support component selection based on inventory and compliance requirements.

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance. Parts 4435.0022, 4430.0683, 4430.1486, and 4430.2103 carry additional international certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077), providing expanded regulatory acceptance for applications requiring multi-standard compliance. Selection between TA35 and TA45 series variants is determined by mechanical fit within the target panel assembly, as electrical performance is identical. Inventory levels range from 718 to 1677 units across all equivalents, supporting procurement flexibility. The main part 4435.0283 (TA35 series, 1110 units) and 4435.0022 (TA35 series, 1677 units) are recommended as primary selections within the TA35 family. For TA45 series applications, 4430.3416 (1151 units) and 4430.3377 (1135 units) offer highest availability.

Frequently Asked Questions (FAQ)

Q: Can TA35 and TA45 series parts be used interchangeably? A: Yes. Both series maintain identical electrical ratings (3A, 240V AC, 60V DC) and mechanical interfaces (panel mount, rocker actuator, dual-pole). Series designation reflects internal design evolution but does not affect substitution eligibility for this rating class.

Q: What is the significance of the additional certifications on parts 4435.0022, 4430.0683, 4430.1486, and 4430.2103? A: These parts carry CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 certifications. These certifications expand regulatory acceptance in North American, European, and international markets. Selection of certified variants is required for applications subject to these standards.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed parts, including the main part 4435.0283, are ROHS3 compliant.

Q: Does part number selection affect electrical performance? A: No. All substitute parts deliver identical electrical performance: 3A current rating, 240V AC / 60V DC voltage rating, and thermal breaker operation. Part number differences reflect manufacturing lot, series revision, or internal design updates that do not alter functional specifications.

Q: What packaging format is used for all parts? A: All parts are supplied in bulk packaging.

Q: How should I select between available substitutes? A: Selection criteria are: (1) mechanical fit within the target panel assembly (TA35 vs. TA45 series), (2) regulatory certification requirements (standard vs. multi-certified variants), and (3) inventory availability. All parts are electrically and functionally equivalent.
