SCHURTER 4430.1204 Equivalent & Substitute Parts

Part Overview

The SCHURTER 4430.1204 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 and carries full international approvals including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 certifications. The part is ROHS3 compliant and REACH unaffected. Equivalent and substitute parts within the TA45 series maintain identical electrical and mechanical specifications, enabling direct functional replacement in applications requiring thermal circuit protection across mixed AC/DC voltage environments.

Substitute Part Grouping Explanation

Substitution within this product family 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 and mechanical characteristics. Product status differentiation (Active versus Obsolete) and compliance certifications are provided for engineering selection purposes but do not affect functional interchangeability. Parts with Obsolete status (4430.0617, 4430.0764) remain electrically equivalent but may present supply chain considerations.

Engineering Selection Recommendations

For new designs and production applications, Active status parts are preferred: 4430.1204, 4430.1147, 4430.1158, 4430.2487, 4430.2736, 4430.2781, 4430.2906, 4430.3172, and 4430.3295. These parts carry full international regulatory approvals (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077) and maintain REACH unaffected status with Not Applicable MSL classification.

Parts 4430.0617 and 4430.0764 are classified as Obsolete and carry REACH Affected designation. While electrically equivalent, these parts present long-term supply chain risk and should be reserved for legacy system maintenance or retrofit applications where original part continuity is required. Obsolete parts may have restricted REACH compliance status requiring additional documentation for certain regulatory jurisdictions.

All Active parts are ROHS3 compliant and suitable for applications requiring environmental compliance across EU, China, and equivalent regulatory frameworks.

Frequently Asked Questions (FAQ)

Q: Can 4430.0617 or 4430.0764 be used as direct replacements for 4430.1204?

A: Yes, from an electrical and mechanical standpoint. Both obsolete parts maintain identical voltage ratings (240 V AC / 60 V DC), thermal breaker type, 2-pole rocker panel mount configuration, and TA45 series designation. However, obsolete parts carry REACH Affected status, which may require additional compliance documentation depending on end-use jurisdiction and customer requirements.

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

A: Active parts are in current production with ongoing manufacturer support and guaranteed long-term availability. Obsolete parts are no longer manufactured and represent legacy inventory. While functionally equivalent, obsolete parts should not be specified for new designs due to supply chain discontinuation risk.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed, including obsolete variants, carry ROHS3 compliance certification. This applies to both Active and Obsolete status parts.

Q: What certifications apply to the main part 4430.1204?

A: The part carries CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 approvals. These certifications cover North American (CSA, UL), European (EN), and international (IEC, GB) regulatory requirements for thermal circuit breakers.

Q: Can I substitute an Active part for an Obsolete part in existing equipment?

A: Yes. All Active parts within this family are electrically and mechanically equivalent to obsolete variants. Substitution is functionally transparent provided the panel mount opening and rocker actuator interface remain unchanged.

Q: What is the REACH status difference between parts?

A: Active parts are REACH Unaffected, indicating no restricted substances of concern under current REACH regulations. Obsolete parts (4430.0617, 4430.0764) are REACH Affected, requiring additional compliance verification for certain applications or export jurisdictions.
