Engineering Selection Recommendations

All substitute parts listed maintain Active product status with ROHS3 compliance and REACH unaffected designation, matching the regulatory and environmental requirements of the primary part 4430.0977. Selection among equivalent parts may be based on inventory availability and supply chain considerations. Parts with documented approval agencies (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077) provide additional certification documentation where required by application standards. Part 4430.2303 offers the highest inventory level at 3604 units, while all alternatives maintain identical electrical and mechanical specifications for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can all listed substitute parts replace the 4430.0977 in existing applications?

A: Yes. All substitute parts maintain identical current ratings (5A), voltage ratings (240V AC / 60V DC), breaker type (thermal), mounting configuration (panel mount), actuator type (rocker), and pole count (2). Direct substitution is supported without circuit modification.

Q: What determines if a part is a valid substitute for the 4430.0977?

A: Substitution eligibility requires matching specifications across all critical parameters: 5A current rating, 240V AC and 60V DC voltage ratings, thermal breaker type, panel mount configuration, rocker actuator, and 2-pole design within the TA45 series. All listed parts meet these criteria.

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

A: The primary part 4430.0977 does not list specific approval agencies. Several substitute parts document compliance with CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. Applications requiring specific certifications should reference the approval documentation for the selected part number.

Q: Does packaging differ among these substitute parts?

A: All parts are supplied in Bulk packaging. No alternative packaging configurations are listed for this product group.

Q: Which substitute part offers the best inventory availability?

A: Part 4430.2303 maintains the highest inventory level at 3604 units. All substitute parts are classified as New Original In Stock.
