Circuit Breaker Thermal 16A 277VAC 28VDC SCHURTER 4411.0089

Part Overview

The SCHURTER 4411.0089 is a thermal circuit breaker designed for panel mount applications with a 16A current rating across dual voltage specifications (277V AC and 28V DC). This single-pole, push-to-reset breaker operates within the T13 series and maintains Active product status with full ROHS3 compliance. Substitute parts become necessary when addressing inventory constraints, supply chain disruptions, or specific procurement requirements while maintaining identical electrical and mechanical performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for thermal circuit breakers is determined by strict equivalence across electrical and mechanical parameters. The SCHURTER 4411.0018 qualifies as a parametric equivalent based on the following criteria:

• Identical current rating: 16A
• Identical AC voltage rating: 277V
• Identical DC voltage rating: 28V
• Identical breaker type: Thermal
• Identical mounting configuration: Panel Mount, single-pole
• Identical actuator mechanism: Push to Reset
• Identical series classification: T13
• Identical regulatory compliance: ROHS3 Compliant, REACH Unaffected

Both parts share the same ECCN (EAR99) and HTSUS classification (8536.20.0020), confirming functional and regulatory interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the SCHURTER 4411.0089 and 4411.0018 maintain Active product status with identical compliance certifications (ROHS3 Compliant, REACH Unaffected). Selection between these parts should be based on availability and procurement lead times, as they are functionally and mechanically equivalent. Both parts carry the same regulatory classification and are suitable for direct substitution in panel mount thermal circuit breaker applications requiring 16A protection at 277V AC or 28V DC.

Frequently Asked Questions (FAQ)

Q: Can the 4411.0018 directly replace the 4411.0089 in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical ratings (16A, 277V AC, 28V DC), thermal operation, panel mount configuration, and push-to-reset actuation. No design modification is required.

Q: Are there any differences in physical dimensions or mounting footprint?

A: The provided specifications do not include dimensional data. Consult the respective datasheets to confirm mechanical compatibility if physical fit is a design constraint.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts carry identical ROHS3 compliance, REACH Unaffected status, EAR99 ECCN classification, and HTSUS code 8536.20.0020.

Q: What determines substitution eligibility for thermal circuit breakers?

A: Substitution is based on matching current rating, voltage ratings (AC and DC), breaker type, mounting method, pole configuration, actuator type, and series classification. All these parameters are identical between the 4411.0089 and 4411.0018.

Q: Is there a preferred part for new designs?

A: Both parts are Active status. Selection should be based on current inventory availability and procurement timelines, as they are functionally equivalent.
