Substitute Part Grouping Explanation

Substitution eligibility for SCHURTER 4430.1147 is determined by strict parametric equivalence across the following criteria:

Voltage Rating (AC/DC): 240 V AC and 60 V DC
Breaker Type: Thermal operation
Mounting Configuration: Panel mount with rocker actuation
Pole Configuration: Dual-pole (2-pole)

Engineering Selection Recommendations

For new designs and production applications, Active status parts are preferred: 4430.1147, 4430.1158, 4430.2487, 4430.2736, 4430.2781, 4430.2906, 4430.3172, 4430.3295, and 4430.3331. These parts maintain current manufacturer support and full compliance with international safety standards.

Parts 4430.1147, 4430.2487, 4430.2781, and 4430.2906 carry explicit approval agency certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077) and REACH Unaffected status, making them optimal for regulated applications requiring documented compliance documentation.

Obsolete parts 4430.0617 and 4430.0764 remain functionally equivalent but are subject to supply discontinuation. These parts are suitable only for legacy system maintenance where existing inventory exists or for applications where long-term availability is not a requirement.

Frequently Asked Questions (FAQ)

Q: Can 4430.0617 or 4430.0764 be used as direct replacements for 4430.1147?

A: Yes. Both obsolete parts maintain identical electrical ratings (240 V AC, 60 V DC), thermal breaker operation, dual-pole configuration, and panel mount rocker actuation. Functional interchangeability is confirmed. However, obsolete status indicates discontinued manufacturer support and potential supply constraints.

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

A: Active parts (4430.1147, 4430.1158, 4430.2487, 4430.2736, 4430.2781, 4430.2906, 4430.3172, 4430.3295, 4430.3331) receive ongoing manufacturer support, quality assurance, and availability guarantees. Obsolete parts (4430.0617, 4430.0764) are no longer manufactured and rely on existing inventory. Electrical and mechanical specifications remain identical.

Q: Does REACH compliance status affect substitution eligibility?

A: REACH status does not alter electrical or mechanical interchangeability. Parts marked REACH Unaffected (4430.1147, 4430.1158, 4430.2487, 4430.2736, 4430.2781, 4430.2906, 4430.3172, 4430.3295, 4430.3331) and REACH Affected (4430.0617, 4430.0764) function identically. Selection should consider regulatory requirements specific to the end application and geographic market.

Q: Are all substitute parts packaged identically?

A: Yes. All parts in this equivalency group are supplied in Bulk packaging configuration, maintaining consistent handling and storage requirements.

Q: Which parts carry full international safety certifications?

A: Parts 4430.1147, 4430.2487, 4430.2781, and 4430.2906 explicitly list approval agency certifications: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. Other Active parts maintain ROHS3 compliance but do not list explicit certification documentation in the provided specifications.
