SCHURTER 4430.0765 Thermal Circuit Breaker 12A 240VAC 60VDC Equivalent & Substitute Parts

Part Overview

The SCHURTER 4430.0765 is a thermal circuit breaker rated for 12A at 240V AC and 60V DC, featuring a rocker panel mount actuator with 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 REACH unaffected.

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits selection from functionally identical alternatives within the same electrical and mechanical parameter set.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters: current rating (12A), voltage ratings (240V AC / 60V DC), breaker type (thermal), mounting configuration (panel mount rocker), pole count (2-pole), and regulatory compliance certifications. All substitute parts listed maintain identical electrical specifications and mechanical form factors, ensuring direct interchangeability without circuit redesign or mechanical modification.

The substitute parts are grouped into two series classifications: TA45 series (primary equivalents) and TA35 series (alternative series with identical electrical parameters). Series designation does not affect electrical or mechanical compatibility for this application.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and comply with the same regulatory framework: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. All parts are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance restrictions.

Selection among equivalent parts should be based on inventory availability and supply chain considerations. The TA45 series parts (4430.0024, 4430.1034, 4430.1637, 4430.242, 4430.2693, 4430.3041, 4430.3223, 4430.3263) represent the primary equivalent group. The TA35 series parts (4435.0092, 4435.0223) provide alternative sourcing within a different series designation while maintaining identical electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can TA35 series parts replace TA45 series parts in existing designs? A: Yes. Both series maintain identical electrical ratings (12A, 240V AC, 60V DC), mounting configuration (panel mount rocker), pole count (2-pole), and breaker type (thermal). Series designation does not affect functional compatibility.

Q: Are all substitute parts certified to the same standards as the primary part? A: All TA45 series substitutes carry identical certifications: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. TA35 series parts are ROHS3 compliant and REACH unaffected but do not list the same approval agencies in the provided data. Verify specific certification requirements for your application.

Q: What is the difference between these part numbers if all electrical parameters are identical? A: Part number variations reflect internal SCHURTER manufacturing designations, packaging configurations, or internal revision levels. From an electrical and mechanical standpoint, all listed parts are functionally equivalent for this 12A 240VAC 60VDC thermal circuit breaker application.

Q: Can I mix different part numbers in the same assembly? A: Yes. All parts meet identical electrical specifications and mechanical form factors, permitting interchangeable use within the same circuit design without modification.

Q: Which part should I select if multiple substitutes are available? A: Selection should be based on current inventory levels and supply chain lead times. All parts are functionally equivalent. The 4430.242 (1168 pcs) and 4430.0765 (1171 pcs) offer the highest inventory availability.
