Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 4435.0018 is determined by the following critical parameters:

• Voltage Rating: 240 V AC/DC operation capability
• Breaker Type: Thermal protection mechanism
• Number of Poles: Three-pole configuration
• Actuator Type: Rocker panel mount interface
• Mounting Type: Panel mount form factor
• Regulatory Compliance: ROHS3 and REACH status alignment

The substitute part 4435.0486 maintains functional equivalence through identical thermal breaker operation, three-pole configuration, and panel mount design. Both parts are manufactured by SCHURTER Inc. and share the same HTSUS classification (8536.20.0020), confirming tariff and regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 4435.0486 is the manufacturer-designated substitute for the obsolete 4435.0018. Selection of this substitute is supported by:

• Active product status, ensuring ongoing availability and manufacturing support
• ROHS3 compliance maintained across both parts
• Improved REACH status (unaffected vs. affected), reducing regulatory burden in supply chain management
• Identical HTSUS classification, confirming equivalent tariff treatment
• Manufacturer recommendation, indicating functional and mechanical compatibility

The transition from the obsolete 4435.0018 to the active 4435.0486 is appropriate for new designs and replacement applications requiring thermal circuit breaker protection in 240 V AC/DC systems.

Frequently Asked Questions (FAQ)

Q: What makes the 4435.0486 a suitable substitute for the 4435.0018?

A: Both parts are SCHURTER thermal circuit breakers with identical HTSUS classification. The 4435.0486 is the manufacturer-recommended replacement, offering active product status and improved REACH compliance while maintaining ROHS3 certification.

Q: Why is the 4435.0018 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The manufacturer has designated the 4435.0486 as the current equivalent for new applications and ongoing system support.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in bulk packaging. Inventory availability differs, with 628 units of the 4435.0018 and 865 units of the 4435.0486 currently in stock.

Q: What is the significance of REACH Unaffected status for the 4435.0486?

A: REACH Unaffected status indicates the substitute part does not contain substances of very high concern (SVHC) listed under REACH regulations, simplifying compliance documentation and supply chain management compared to the REACH Affected main part.

Q: Can the 4435.0486 be used in existing systems designed for the 4435.0018?

A: Substitution is supported by manufacturer recommendation and identical thermal breaker classification. Physical and electrical compatibility should be confirmed through system integration documentation.
