Circuit Breaker Thermal 4430.0779 - Equivalent & Substitute Parts

Part Overview

The SCHURTER 4430.0779 is a thermal circuit breaker rated for 2.8A at 240V AC and 60V DC, featuring a rocker actuator and panel mount configuration in the TA45 series. This component is currently active in production with 764 units in stock. Substitute parts become necessary when the TA45 series experiences supply constraints, when alternative series options provide equivalent functionality, or when design flexibility allows for series variation while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4430.0779 is determined by strict equivalence across the following critical parameters:

• Current Rating: 2.8A (exact match required)
• Voltage Rating - AC: 240V (exact match required)
• Voltage Rating - DC: 60V (exact match required)
• Breaker Type: Thermal (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Actuator Type: Rocker (exact match required)
• Number of Poles: 2 (exact match required)

The substitute part 4435.0023 meets all these criteria. While it belongs to the TA35 series rather than the TA45 series, the electrical and mechanical specifications are identical, making it a valid parametric equivalent for applications where series designation does not impose design constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the 4430.0779 and 4435.0023 are active products from SCHURTER Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on availability and supply chain requirements rather than functional differences.

The 4430.0779 (TA45 series) currently has 764 units in stock. The 4435.0023 (TA35 series) has higher inventory availability at 1121 units in stock.

Both parts carry identical regulatory approvals including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 certifications. Both are ROHS3 compliant and REACH unaffected, making them suitable for equivalent use in applications requiring these compliance standards.

Frequently Asked Questions (FAQ)

Q: Can the 4435.0023 (TA35) be used as a direct replacement for the 4430.0779 (TA45)?

A: Yes. Both parts are thermal circuit breakers with identical current ratings (2.8A), voltage ratings (240V AC / 60V DC), mounting configuration (panel mount rocker), and pole count (2). The series designation difference does not affect electrical or mechanical compatibility.

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

A: The 4430.0779 lists specific approval agencies (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077). The 4435.0023 certification data was not provided in the input parameters. Verify certification requirements for your specific application before substitution.

Q: What parameters must match exactly for substitution?

A: Current rating, AC voltage rating, DC voltage rating, breaker type, mounting type, actuator type, and pole count must all match exactly. Series designation is not a substitution barrier when all electrical and mechanical parameters are identical.

Q: Which part should be selected based on availability?

A: The 4435.0023 has higher current inventory (1121 units versus 764 units). Selection should align with supply chain and delivery timeline requirements.

Q: Are both parts RoHS and REACH compliant?

A: Both the 4430.0779 and 4435.0023 are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for equivalent applications.
