Circuit Breaker Thermal 10A 240VAC 60VDC SCHURTER 4430.1294

Part Overview

The SCHURTER 4430.1294 is an active thermal circuit breaker designed for panel mount applications. This component provides overcurrent protection in AC and DC circuits with a 10-ampere current rating and dual voltage capability (240V AC / 60V DC). The rocker actuator with red illumination at 110V nominal provides visual status indication. This part is actively manufactured and fully compliant with international safety standards including UL1077, IEC 60934, EN 60934, CSA C22.2 No 235, and GB 17701. Substitute parts are identified to support procurement flexibility and inventory management when the primary part number becomes unavailable or when alternative sourcing is required.

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 4430.1294 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 4430.3427 qualifies as a parametric equivalent based on identical specifications in the following categories:

Electrical Parameters: Current rating (10A), AC voltage rating (240V), DC voltage rating (60V), and illumination voltage (110V nominal) are identical.

Mechanical Parameters: Mounting type (panel mount), actuator type (rocker), number of poles (2), and illumination color (red) are identical.

Functional Classification: Both parts are thermal circuit breakers within the TA45 series.

Regulatory Compliance: Both parts carry identical approval agency certifications and RoHS3 compliance status.

Manufacturing Status: Both parts are active products from SCHURTER Inc., ensuring continued availability and support.

No parameter deviation is permitted for substitution within this grouping. Parts must match across all specified electrical, mechanical, and compliance criteria.

Parameter Comparison

Engineering Selection Recommendations

Both the primary part number 4430.1294 and the substitute 4430.3427 are active products manufactured by SCHURTER Inc. and carry identical regulatory certifications across all major approval agencies (UL1077, IEC 60934, EN 60934, CSA C22.2 No 235, GB 17701). Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

Selection between these parts should be based on procurement availability and inventory status. The 4430.1294 currently has 1023 units in stock, while the 4430.3427 has 954 units available. Both parts are suitable for direct substitution in applications requiring a 10-ampere thermal circuit breaker with 240V AC / 60V DC dual voltage capability and panel mount rocker actuator configuration.

Frequently Asked Questions (FAQ)

Q: Can the 4430.3427 be used as a direct replacement for the 4430.1294?

A: Yes. The 4430.3427 is a parametric equivalent with identical electrical ratings (10A, 240V AC, 60V DC), mechanical configuration (panel mount, rocker actuator, 2-pole), illumination specifications (red, 110V nominal), and regulatory certifications. Direct substitution is supported without circuit modification.

Q: Are there any differences in approval certifications between these parts?

A: No. Both parts carry identical certifications: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. Both are ROHS3 compliant and REACH unaffected.

Q: What determines whether a part qualifies as a substitute?

A: Substitution requires identical specifications across all electrical parameters (current rating, AC voltage, DC voltage, illumination voltage), mechanical parameters (mounting type, actuator type, pole count, illumination color), functional classification (thermal breaker type), and regulatory compliance status. Any deviation disqualifies a part from this substitution group.

Q: Can I use a substitute part with different current or voltage ratings?

A: No. The substitute part must have identical current and voltage ratings. Parts with different electrical specifications are not interchangeable and require separate circuit analysis and approval.

Q: What is the packaging format for these parts?

A: Both parts are supplied in bulk packaging format.
