SCHURTER 4430.0003 Circuit Breaker Thermal 240VAC 60VDC Equivalent & Substitute Parts

Part Overview

The SCHURTER 4430.0003 is a thermal circuit breaker rated for 240 V AC and 60 V DC operation with rocker panel mount actuator and dual-pole configuration. This part is classified as obsolete and requires identification of equivalent alternatives for ongoing system support and procurement. Substitute parts maintain identical electrical ratings and mechanical form factors while offering improved availability through active product status designations.

Substitute Part Grouping Explanation

Substitution eligibility for SCHURTER 4430.0003 is determined by strict equivalence across the following parameters:

Voltage Rating - AC: 240 V (mandatory match)
Voltage Rating - DC: 60 V (mandatory match)
Breaker Type: Thermal (mandatory match)
Actuator Type: Rocker (mandatory match)
Mounting Type: Panel Mount (mandatory match)
Number of Poles: 2 (mandatory match)
Series: TA45 (mandatory match)

All substitute parts listed maintain these electrical and mechanical specifications. Current rating variations are permitted where the original part number does not specify a current rating constraint. RoHS3 compliance is maintained across all alternatives.

Engineering Selection Recommendations

For applications currently utilizing SCHURTER 4430.0003, the following selection criteria apply:

Primary Recommendation - Active Status Parts: Parts 4430.1147, 4430.1158, 4430.1204, 4430.1962, 4430.2087, 4430.2226, and 4430.2487 are classified as active products with full manufacturing support and compliance certifications. These parts are preferred for new designs and ongoing procurement due to sustained availability and regulatory compliance documentation.

Secondary Recommendation - Specified Current Rating: Part 4430.161 provides an active alternative with explicit 20A current rating specification. This part is suitable for applications where current rating specification is a design requirement.

Tertiary Alternatives - Obsolete Status: Parts 4430.0617 and 4430.0764 maintain electrical and mechanical equivalence but retain obsolete product status. These alternatives are suitable only for legacy system maintenance where active parts cannot be accommodated.

All substitute parts maintain ROHS3 compliance and identical voltage ratings (240 V AC / 60 V DC). Selection between active alternatives should be based on current rating requirements and specific application constraints.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 4430.161 replace SCHURTER 4430.0003 in existing applications?

A: Yes. Part 4430.161 maintains identical electrical ratings (240 V AC / 60 V DC), breaker type (thermal), actuator configuration (rocker), mounting method (panel mount), and pole count (2). The specified 20A current rating does not preclude substitution where the original part does not specify a current constraint.

Q: What is the difference between active and obsolete product status alternatives?

A: Active status parts (4430.1147, 4430.1158, 4430.1204, 4430.1962, 4430.2087, 4430.2226, 4430.2487) are currently manufactured with full compliance documentation and sustained supply. Obsolete status parts (4430.0617, 4430.0764) are no longer in active production but remain electrically and mechanically equivalent. Active parts are preferred for new procurement.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance status consistent with the original SCHURTER 4430.0003.

Q: Do substitute parts require different panel cutout dimensions or mounting hardware?

A: No. All substitute parts maintain identical panel mount configuration and rocker actuator form factor. Existing panel cutouts and mounting hardware are compatible across all listed alternatives.

Q: Which substitute part should be selected for new equipment designs?

A: For new designs, select from active status parts: 4430.1147, 4430.1158, 4430.1204, 4430.1962, 4430.2087, 4430.2226, or 4430.2487. These parts provide sustained manufacturing support and full compliance certifications. If current rating specification is required, 4430.161 is the designated alternative.
