SCHURTER 4430.1876 Circuit Breaker Thermal 4A 240VAC 60VDC Equivalent & Substitute Parts

Part Overview

The SCHURTER 4430.1876 is a thermal circuit breaker rated for 4A at 240V AC and 60V DC, featuring a rocker actuator and panel mount configuration in the TA45 series. This component is active in production and ROHS3 compliant. Substitute parts are necessary when the primary part number is unavailable from inventory or when design flexibility permits selection from equivalent alternatives within the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by exact equivalence across the following critical parameters: current rating (4A), voltage ratings (240V AC / 60V DC), breaker type (thermal), mounting configuration (panel mount), actuator style (rocker), and pole count (2). All listed substitute parts maintain these specifications. Series designation (TA45 or TA35) and individual part number variations do not affect electrical or mechanical compatibility within this product category. Inventory availability is provided for reference but does not determine substitution validity.

Engineering Selection Recommendations

All listed substitute parts are manufactured by SCHURTER Inc. and maintain active product status. Each part carries ROHS3 compliance and REACH unaffected status, meeting the same regulatory requirements as the primary part 4430.1876. Selection among these equivalents may be based on inventory availability and procurement lead time. Parts designated TA45 series (4430.1876, 4430.0706, 4430.2421, 4430.2437, 4430.3021, 4430.3216, 4430.34, 4430.3676, 4430.3742) and TA35 series (4435.0009, 4435.0125) are electrically and mechanically interchangeable within the specified parameters.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for 4430.1876? A: Exact equivalence in current rating (4A), AC voltage (240V), DC voltage (60V), breaker type (thermal), mounting style (panel mount), actuator configuration (rocker), and pole count (2) qualifies a part as a direct substitute.

Q: Are TA45 and TA35 series parts interchangeable? A: Yes. Both series maintain identical electrical specifications and mechanical mounting requirements for this 4A 240VAC 60VDC thermal breaker configuration.

Q: Does RoHS compliance affect substitution eligibility? A: All substitute parts listed are ROHS3 compliant, matching the compliance status of 4430.1876. Compliance status is uniform across all alternatives.

Q: Can I use a substitute part with different voltage ratings? A: No. Voltage ratings must remain 240V AC and 60V DC. Parts with different voltage specifications are not substitutes for this application.

Q: What role does inventory quantity play in substitution? A: Inventory levels are provided for reference only and do not affect technical substitution validity. Selection may consider availability for procurement purposes.

Q: Are there any mechanical differences between substitute part numbers? A: All substitute parts share identical mounting type (panel mount), actuator type (rocker), and pole configuration (2-pole). Mechanical compatibility is maintained across all alternatives.
