SCHURTER 4430.3172 Thermal Circuit Breaker Equivalent & Substitute Parts

Part Overview

The SCHURTER 4430.3172 is a thermal circuit breaker rated for 240 V AC and 60 V DC operation with a 2-pole rocker actuator panel mount configuration in the TA45 series. This component is currently in active product status with 800 units in stock. Thermal circuit breakers of this specification are essential for overcurrent protection in dual-voltage applications. Substitute parts become necessary when addressing supply chain constraints, design revisions, or when integrating components from existing inventory across multiple production batches.

Substitute Part Grouping Explanation

Substitution eligibility for the 4430.3172 is determined by strict parametric matching across the following criteria:

Voltage Rating - AC: 240 V (mandatory match)
Voltage Rating - DC: 60 V (mandatory match)
Breaker Type: Thermal (mandatory match)
Mounting Type: Panel Mount (mandatory match)
Actuator Type: Rocker (mandatory match)
Number of Poles: 2 (mandatory match)
Series: TA45 (mandatory match)
Packaging: Bulk (mandatory match)

All substitute parts listed maintain identical electrical and mechanical specifications to the main part number. Product status variations (Active vs. Obsolete) and compliance certifications are documented for engineering selection purposes but do not disqualify substitution eligibility based on parametric equivalence.

Engineering Selection Recommendations

All listed substitute parts maintain full parametric equivalence to the 4430.3172 across electrical and mechanical specifications. Selection between active and obsolete status parts should be based on long-term supply chain strategy and product lifecycle requirements.

Active status parts (4430.1147, 4430.1158, 4430.2487, 4430.2736, 4430.2781, 4430.2906, 4430.3295, 4430.3331) are recommended for new designs and ongoing production to ensure sustained availability and manufacturer support.

Obsolete status parts (4430.0617, 4430.0764) are suitable for legacy system maintenance and repair applications where existing inventory must be utilized. These parts carry REACH Affected status, which may impose additional regulatory documentation requirements depending on application jurisdiction.

Compliance certifications including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 are documented for parts 4430.1147, 4430.2487, 4430.2781, and 4430.2906. These certifications should be cross-referenced with application-specific regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can 4430.3172 be directly replaced with any part from the substitute list?

A: Yes. All substitute parts maintain identical voltage ratings (240 V AC / 60 V DC), thermal breaker type, 2-pole rocker actuator configuration, and panel mount form factor. Direct substitution is parametrically valid.

Q: What is the difference between Active and Obsolete status parts?

A: Active status indicates current manufacturer production and ongoing support. Obsolete status indicates discontinued production. Obsolete parts may have limited availability and no manufacturer technical support. For new designs, Active status parts are preferred.

Q: Are there any compliance differences between substitute parts?

A: All parts are ROHS3 Compliant. Parts 4430.0617 and 4430.0764 carry REACH Affected status, while remaining parts are REACH Unaffected. Parts 4430.1147, 4430.2487, 4430.2781, and 4430.2906 include documented approval agency certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077). Verify compliance requirements for your specific application jurisdiction.

Q: Which substitute part has the highest inventory availability?

A: Part 4430.1147 has the highest inventory with 1180 units in stock, followed by 4430.3295 with 1160 units and 4430.2487 with 1151 units.

Q: Can obsolete parts be used in new production?

A: Obsolete parts are not recommended for new production designs due to discontinued manufacturer support and uncertain long-term availability. Reserve obsolete inventory for legacy system maintenance and repair applications only.
