Engineering Selection Recommendations

All listed substitute parts are Active status components manufactured by SCHURTER Inc. and comply with the same regulatory standards: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. All parts are ROHS3 compliant and carry REACH Unaffected status. Selection among these equivalent parts may be based on inventory availability and lead time requirements, as electrical and mechanical specifications are identical across all options.

Frequently Asked Questions (FAQ)

Q: Can any of these substitute parts replace the 4430.1818 directly?

A: Yes. All listed parts are parametric equivalents with identical current rating (15A), voltage ratings (240V AC / 60V DC), breaker type (thermal), mounting configuration (panel mount), actuator type (rocker), and pole count (2). Direct substitution is valid for applications requiring these specifications.

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

A: Substitution validity is determined by matching the following parameters: current rating, AC and DC voltage ratings, breaker type, mounting type, actuator type, number of poles, and series designation. All listed parts maintain these specifications identically to the main part.

Q: Are there differences in compliance or certifications among these parts?

A: All parts comply with CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. All are ROHS3 compliant and REACH unaffected. Compliance profiles are equivalent across all options.

Q: Does packaging affect substitution?

A: All parts are supplied in Bulk packaging. Packaging format is consistent across the product line and does not affect electrical or mechanical compatibility.

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

A: Selection may be based on inventory availability and procurement lead times. Electrical and mechanical performance is identical across all equivalent parts. Part 4430.1089 currently has the highest inventory level at 2961 pieces.
