Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 0912034 is determined by the following core parameters:

• Current Rating: 4A (exact match required)
• Voltage Rating - DC: 24V (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Number of Poles: 1 (exact match required)

The Phoenix Contact 2909906 satisfies all four core substitution criteria. While the 2909906 employs solid-state breaker technology with lever actuation (compared to the automatic reset mechanism of the 0912034), both components operate within identical electrical specifications and physical mounting constraints.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2909906 is the identified substitute for the obsolete 0912034. Both components share identical electrical ratings (4A, 24VDC) and physical mounting specifications (DIN rail, single pole). The 2909906 maintains active product status and meets current RoHS3 compliance requirements, whereas the 0912034 is obsolete. Both components carry identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2909906 directly replace the 0912034 in existing installations?

A: Yes, provided the circuit design does not depend on the automatic reset behavior specific to the 0912034. Both components meet identical electrical and mechanical specifications for 4A 24VDC DIN rail applications.

Q: What is the primary functional difference between these two breakers?

A: The 0912034 uses automatic reset actuation, while the 2909906 employs solid-state technology with manual lever actuation. This affects how the breaker responds to overcurrent conditions and requires operator intervention on the 2909906.

Q: Are there packaging differences between these parts?

A: The 2909906 is supplied in box packaging. The 0912034 packaging specification was not provided in the technical data.

Q: Do both parts meet current compliance standards?

A: The 2909906 meets ROHS3 compliance and is REACH affected. The 0912034 meets RoHS compliance as an obsolete component. Both share identical ECCN (EAR99) and HTSUS (8536.20.0020) classifications.

Q: Why is the 0912034 classified as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The active status of the 2909906 indicates Phoenix Contact's current product direction for 4A 24VDC DIN rail circuit breaker applications.
