Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for thermal circuit breakers is determined by the following critical parameters: breaker type (thermal), voltage ratings (240V AC and 60V DC), mounting configuration (panel mount), actuator style (rocker), pole count (2-pole), illumination type (clear), and regulatory compliance certifications.

The substitute parts identified maintain these core electrical and mechanical specifications. Substitutes are grouped into two categories:

MFR Recommended Substitute: Part 4430.2443 represents the manufacturer-designated replacement with active product status.

Parametric Equivalents: Parts 4430.1129 and 4439.0006 match all critical electrical and mechanical parameters of the original part while maintaining active availability.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: Part 4430.1129 is the preferred substitute. It maintains complete parametric equivalence with the original 4430.1146, including identical voltage ratings, mounting configuration, pole count, illumination specifications, and regulatory certifications. The part holds active product status with higher inventory availability (1140 pcs) and REACH Unaffected classification.

Alternative Selection: Part 4439.0006 provides equivalent electrical and mechanical specifications with active product status. Inventory availability is 896 pcs. This part maintains all critical certifications and ROHS3 compliance.

Manufacturer-Designated Option: Part 4430.2443 is the manufacturer-recommended replacement with active status and 651 pcs inventory. Detailed parametric specifications are not provided for this part; verification of voltage ratings and mounting configuration with SCHURTER technical documentation is necessary prior to implementation.

All substitute parts maintain ROHS3 compliance and EAR99 export classification consistent with the original part.

Frequently Asked Questions (FAQ)

Q: What determines if a circuit breaker can substitute for the 4430.1146?

A: Substitution requires matching thermal breaker type, 240V AC and 60V DC voltage ratings, panel mount configuration, rocker actuator, 2-pole design, clear illumination at 110V nominal, and compliance with CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 standards.

Q: Why is the 4430.1146 being discontinued?

A: The part is classified as obsolete. Active alternatives with identical specifications are available from SCHURTER Inc.

Q: Can I use 4430.2443 as a direct replacement?

A: Part 4430.2443 is the manufacturer-recommended substitute. However, detailed parametric specifications for voltage ratings and mounting type are not provided in available documentation. Confirmation with SCHURTER technical resources is required before implementation.

Q: What is the difference between 4430.1129 and 4439.0006?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The primary difference is inventory availability (1140 pcs for 4430.1129 versus 896 pcs for 4439.0006) and REACH classification (Unaffected for both).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitutes maintain ROHS3 compliance consistent with the original 4430.1146.

Q: What packaging options are available?

A: The original part packaging is not specified. Substitute 4430.2443 is available in bulk packaging. Substitutes 4430.1129 and 4439.0006 packaging specifications are not detailed in available data.
