Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 0902072 is determined by the following critical parameters:

• Current Rating: 10A (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Actuator Type: Lever (exact match required)
• Number of Poles: 1 (exact match required)

The substitute part Phoenix Contact 1019980 satisfies all mandatory substitution criteria. This part belongs to the TMC 7 series and maintains identical functional specifications for current rating, breaker type, mounting configuration, and actuation method. The substitute is classified as active product status, ensuring continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1019980 is the qualified substitute for the obsolete 0902072. Both components share identical core specifications: 10A thermal magnetic protection, lever actuation, single-pole configuration, and DIN rail mounting. The substitute part offers enhanced compliance status (ROHS3) and active product availability, eliminating supply chain risk associated with the obsolete original part.

The substitute provides explicit voltage ratings (277 V AC, 60 V DC) not documented in the original part specification. These ratings establish the operational envelope for the substitute and should be verified against system requirements prior to installation.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1019980 directly replace the 0902072 in existing installations?

A: Yes. Both parts are thermal magnetic circuit breakers with identical current ratings (10A), lever actuation, single-pole configuration, and DIN rail mounting. The substitute maintains functional equivalence for the core protection function.

Q: What is the significance of the voltage ratings on the substitute part?

A: The 1019980 specifies 277 V AC and 60 V DC operating limits. These define the maximum voltage the breaker can safely interrupt. The original 0902072 does not document voltage ratings in the provided specification. System voltage must not exceed these limits.

Q: Why is the original part classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Phoenix Contact 1019980 (TMC 7 series) represents the active product line replacement, ensuring long-term availability and support.

Q: Are there packaging differences between these parts?

A: The original part number does not specify packaging details. The substitute is supplied in box packaging. Verify packaging requirements for your procurement and logistics processes.

Q: What compliance certifications apply to the substitute?

A: The 1019980 is ROHS3 compliant and REACH affected. Both parts carry the same ECCN (EAR99) and HTSUS (8536.20.0040) classifications for export and tariff purposes.
