SCHURTER 4430.3361 Thermal Circuit Breaker Equivalent & Substitute Parts

Part Overview

The SCHURTER 4430.3361 is a thermal circuit breaker rated for 240 V AC and 60 V DC operation with rocker panel mount actuation and dual-pole configuration. This component is classified as Active product status with full compliance to CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 standards. Identifying equivalent and substitute parts is necessary when addressing inventory constraints, supply chain disruptions, or design flexibility requirements while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for SCHURTER TA45 series thermal circuit breakers is determined by strict equivalence across the following parameters: voltage rating (240 V AC / 60 V DC), breaker type (thermal), mounting configuration (panel mount rocker), pole count (2-pole), and series designation (TA45). All substitute parts listed maintain identical electrical specifications and mechanical form factors. Product status variations (Active vs. Obsolete) and compliance certifications are documented to support engineering selection decisions but do not disqualify substitution based on functional equivalence.

Engineering Selection Recommendations

All listed substitute parts maintain functional equivalence to the primary part 4430.3361 across electrical and mechanical specifications. Active status parts (4430.1147, 4430.1158, 4430.2487, 4430.2736, 4430.2781, 4430.2906, 4430.3172, 4430.3295) are preferred for new designs and ongoing production due to current product lifecycle status. Parts 4430.0617 and 4430.0764 carry Obsolete designation and should be reserved for legacy system maintenance or retrofit applications where continuity with existing installations is required.

Compliance certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077) are documented for the primary part 4430.3361 and active substitute parts 4430.1147, 4430.2487, 4430.2781, and 4430.2906. REACH status varies between REACH Unaffected (preferred) and REACH Affected designations; review regulatory requirements for your application jurisdiction.

Frequently Asked Questions (FAQ)

Q: Can obsolete parts 4430.0617 and 4430.0764 be used as direct replacements for 4430.3361?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical voltage ratings (240 V AC / 60 V DC), thermal breaker type, 2-pole rocker panel mount configuration, and TA45 series designation. However, obsolete status indicates discontinued production; use only when inventory availability or legacy system requirements justify the selection.

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

A: Active parts are in current production with ongoing manufacturer support. Obsolete parts are no longer manufactured but may remain available through existing inventory channels. For new designs, select Active status parts to ensure long-term supply chain stability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed parts carry ROHS3 Compliant designation, meeting hazardous substance restrictions across all listed substitute options.

Q: Does REACH status affect substitution eligibility?

A: REACH status indicates regulatory substance compliance requirements. REACH Unaffected parts (4430.3361, 4430.1147, 4430.1158, 4430.2487, 4430.2736, 4430.2781, 4430.2906, 4430.3172, 4430.3295) are preferred for applications subject to EU chemical regulations. REACH Affected parts (4430.0617, 4430.0764) require compliance verification for your specific application and jurisdiction.

Q: Can I mix different part numbers in the same assembly?

A: All listed parts are electrically and mechanically equivalent within the TA45 series specification. Assembly mixing is permissible from a functional standpoint; however, design documentation should specify the approved part number(s) for traceability and supply chain management.

Q: What inventory levels are available for each substitute part?

A: Current inventory ranges from 768 to 1180 pieces across the substitute part family. Verify real-time availability with your supplier before finalizing procurement decisions.
