SCHURTER 4430.2364 Circuit Breaker Thermal 20A 240VAC 60VDC Equivalent & Substitute Parts

Part Overview

The SCHURTER 4430.2364 is a thermal circuit breaker rated for 20A 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 is designed for overcurrent protection in industrial and commercial applications. Substitute parts become necessary when the primary part number is unavailable from inventory, when supply chain disruptions occur, or when equivalent alternatives offer improved lead times while maintaining identical electrical and mechanical specifications.

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the primary part 4430.2364 based on identical electrical ratings, mechanical configuration, and Active product status. Selection among these alternatives should be based on inventory availability and lead time requirements.

Parts with documented approval agency certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077) include: 4430.2364, 4430.0572, 4430.1067, 4430.1068, and 4430.161. These certifications indicate compliance with international safety standards for circuit protection devices.

All substitute parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with environmental and hazardous substance restrictions.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the SCHURTER 4430.2364?

A: Substitution is valid when the alternative part maintains identical specifications across all critical parameters: 20A current rating, 240V AC and 60V DC voltage ratings, thermal breaker type, panel mount configuration, rocker actuator, and dual-pole design. All listed parts meet these criteria.

Q: Are there differences in approval certifications among the substitute parts?

A: Yes. Parts 4430.2364, 4430.0572, 4430.1067, 4430.1068, and 4430.161 carry documented approval agency certifications including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. Other substitutes do not list these certifications in the provided data. Both groups are ROHS3 compliant and REACH Unaffected.

Q: Does Moisture Sensitivity Level (MSL) affect substitution eligibility?

A: No. MSL variations (Vendor Undefined, Not Applicable) do not affect the functional equivalence of these thermal circuit breakers for panel mount applications. All parts are suitable for the same operating environment.

Q: Which substitute part offers the highest current inventory?

A: Part 4430.0988 has the highest inventory at 1097 pieces, followed by 4430.1629 at 1098 pieces. Both are equivalent alternatives with identical electrical and mechanical specifications.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. All substitute parts are parametrically equivalent to 4430.2364 across all provided specifications. They share identical current ratings, voltage ratings, mounting type, actuator configuration, and pole count, making them direct functional replacements.
