SCHURTER 4430.0031 Thermal Circuit Breaker 15A 240VAC 60VDC Equivalent & Substitute Parts

Part Overview

The SCHURTER 4430.0031 is a thermal circuit breaker rated for 15A at 240V AC and 60V DC, featuring a rocker panel mount actuator with dual-pole configuration. This component is classified as Active product status and complies with international safety standards including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. The TA45 series thermal breaker is designed for overcurrent protection in industrial and commercial applications requiring reliable thermal trip characteristics.

Equivalent substitute parts are necessary when the primary part number becomes unavailable, when inventory levels require sourcing from alternative stock locations, or when design flexibility permits selection from qualified alternatives within the same electrical and mechanical parameter set.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and carry equivalent regulatory certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077). Selection between 4430.0031 and any substitute part number is based on availability and inventory levels. Part 4430.1089 currently maintains the highest inventory level at 2961 pieces. All alternatives are ROHS3 compliant and REACH unaffected, meeting current environmental and compliance requirements for industrial circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute 4430.0031 with any of the listed part numbers?

A: Yes. All listed part numbers are parametric equivalents with identical electrical ratings (15A, 240VAC, 60VDC), thermal trip characteristics, rocker actuator configuration, dual-pole design, and panel mount form factor. Direct substitution is permissible without circuit modification.

Q: Are there any differences in thermal trip characteristics between substitute parts?

A: No. All parts are classified as thermal breakers within the TA45 series and maintain identical current and voltage ratings. Thermal trip behavior is equivalent across all listed alternatives.

Q: Do all substitute parts carry the same regulatory approvals?

A: Yes. All substitute parts comply with CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 standards. Regulatory compliance is uniform across the substitution group.

Q: What is the difference between these part numbers if they are all equivalent?

A: The part numbers represent different manufacturing batches, production dates, or internal SCHURTER inventory tracking codes. Electrical and mechanical specifications are identical. Differences are administrative rather than functional.

Q: Can I mix these part numbers in the same application or circuit?

A: Yes. Since all parts are parametric equivalents with identical electrical characteristics, mechanical form factors, and regulatory approvals, they can be used interchangeably in the same circuit or application without functional impact.

Q: Which substitute part should I select if multiple are available?

A: Selection should be based on inventory availability and lead time requirements. Part 4430.1089 currently has the highest stock level (2961 pieces). All alternatives are functionally equivalent for circuit protection applications.

Q: Are these parts suitable for both AC and DC applications?

A: Yes. All parts are rated for 240V AC and 60V DC operation, permitting use in mixed-voltage or dual-voltage protection circuits.
