Circuit Breaker Thermal 300mA 240VAC 60VDC SCHURTER 4430.1427

Part Overview

The SCHURTER 4430.1427 is a thermal circuit breaker designed for panel mount applications with a 300mA current rating and dual voltage capability (240V AC / 60V DC). This component provides overcurrent protection in industrial and commercial electrical systems. The part maintains Active product status with full compliance to international safety standards. Alternative part numbers may be required due to inventory availability, supply chain considerations, or specific procurement requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 4430.1427 is determined by strict equivalence across the following critical parameters:

• Current Rating: 300mA (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)
• Series: TA45 (same product family)
• Approval Certifications: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077 (exact match required)

The substitute part 4430.1605 meets all these criteria and is therefore a parametric equivalent within the TA45 series.

Parameter Comparison

Engineering Selection Recommendations

Both the SCHURTER 4430.1427 and 4430.1605 are Active status components with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Procurement source and cost considerations
• Application-specific documentation requirements

Both parts carry full compliance to CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 standards, confirming suitability for regulated industrial and commercial applications. ROHS3 compliance ensures environmental regulatory adherence across global markets.

Frequently Asked Questions (FAQ)

Q: Can 4430.1605 be used as a direct replacement for 4430.1427?

A: Yes. Both parts are parametric equivalents with identical current ratings (300mA), voltage ratings (240V AC / 60V DC), breaker type (thermal), mounting configuration (panel mount rocker), pole count (2), and approval certifications.

Q: What determines if a part is a valid substitute?

A: Substitution requires exact matching of current rating, AC/DC voltage ratings, breaker type, mounting type, actuator type, number of poles, and approval certifications. Both listed parts meet these criteria.

Q: Are there any packaging differences between these parts?

A: Both parts are supplied in Bulk packaging. No packaging format differences exist between the two part numbers.

Q: Do both parts have the same compliance certifications?

A: Yes. Both 4430.1427 and 4430.1605 carry identical certifications: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. Both are ROHS3 compliant and REACH unaffected.

Q: Which part should I select if both are available?

A: Selection should be based on inventory availability, delivery timeline, and procurement cost. From an engineering standpoint, both parts are functionally and mechanically equivalent for this application.
