Circuit Breaker Thermal 120VAC 60VDC SCHURTER 4430.1189

Part Overview

The SCHURTER 4430.1189 is a thermal circuit breaker designed for 120V AC and 60V DC applications with rocker panel mount actuator and dual-pole configuration. This component is classified as Active product status and maintains full compliance with international safety standards including UL1077, IEC 60934, and CSA C22.2 No 235. The need to identify equivalent substitute parts arises from supply chain considerations, design flexibility requirements, or when alternative voltage ratings better match specific application parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for thermal circuit breakers is determined by the following parameters:

• Mounting Type: Must be Panel Mount to ensure mechanical compatibility with existing enclosure cutouts and installation fixtures
• Actuator Type: Must be Rocker to maintain consistent operator interface and control mechanism
• Number of Poles: Must be 2-pole configuration for equivalent circuit protection topology
• Breaker Type: Must be Thermal to preserve the thermal protection mechanism and response characteristics
• Voltage Ratings: AC and DC voltage ratings must meet or exceed the application requirements; substitutes with higher voltage ratings are acceptable for use in lower voltage applications

The substitute part 4435.0014 shares the core mechanical and functional characteristics (panel mount, rocker actuator, 2-pole thermal breaker) but operates at different voltage ratings (240V AC instead of 120V AC). This part is classified as Obsolete and therefore not recommended for new designs despite technical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 4430.1189 maintains Active product status with full ROHS3 compliance and REACH Unaffected classification, making it the preferred choice for new designs and ongoing production. The part carries comprehensive international approvals including UL1077, IEC 60934, EN 60934, CSA C22.2 No 235, and GB 17701.

The substitute part 4435.0014 is classified as Obsolete and carries REACH Affected status. While it shares identical mechanical form factors and thermal protection characteristics, its obsolete classification and higher AC voltage rating (240V versus 120V) make it unsuitable for direct replacement in new applications. The REACH Affected designation indicates potential regulatory compliance considerations for new procurement.

For applications requiring thermal circuit breaker protection at 120V AC and 60V DC with panel mount rocker actuator configuration, the 4430.1189 is the appropriate selection. No active substitute with equivalent voltage ratings and Active product status is available from the provided data.

Frequently Asked Questions (FAQ)

Q: Can the 4435.0014 be used as a direct replacement for the 4430.1189?

A: While both parts share identical mechanical mounting, actuator type, pole configuration, and thermal protection mechanism, the 4435.0014 operates at 240V AC compared to the 4430.1189's 120V AC rating. Additionally, the 4435.0014 is classified as Obsolete. Direct substitution is not recommended for new designs.

Q: What parameters must match for thermal circuit breaker substitution?

A: The mounting type (Panel Mount), actuator type (Rocker), number of poles (2), and breaker type (Thermal) must remain constant. Voltage ratings in substitute parts must equal or exceed the application requirements.

Q: Why is product status important in component selection?

A: Active product status indicates ongoing manufacturer support, continued availability, and compliance with current regulatory requirements. Obsolete parts may face supply discontinuation and may not meet current environmental or safety standards.

Q: What does REACH Affected status mean for this component?

A: REACH Affected status indicates the component contains substances subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. This may impose additional documentation and compliance requirements for procurement and use in certain jurisdictions.

Q: Are there current-rated alternatives available?

A: The provided data does not include current rating specifications for either part. Current rating information would be required to evaluate additional substitution options beyond the mechanical and voltage parameters listed.
