Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0902292 is determined by the following critical parameters:

• Current Rating: 50A (exact match required)
• Voltage Rating - AC: 277V (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Number of Poles: 2 (exact match required)
• Actuator Type: Lever (exact match required)

The substitute part Phoenix Contact 1020012 meets all mandatory electrical and mechanical parameters. The 1020012 operates at the same current and AC voltage ratings, maintains identical mounting and actuation characteristics, and provides enhanced DC voltage capability (125V DC) not present in the original design. The substitute is classified as active product status with improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1020012 is the direct substitute for the obsolete 0902292. Both components share identical electrical ratings (50A, 277V AC), mechanical configuration (2-pole, lever-actuated, DIN rail mount), and thermal magnetic protection characteristics. The 1020012 provides additional DC voltage capability and maintains active product status with current compliance certifications (ROHS3 Compliant, REACH Unaffected). Selection of the 1020012 eliminates obsolescence risk while preserving all functional requirements of the original specification.

Frequently Asked Questions (FAQ)

Q: Can the 1020012 be used as a direct replacement for the 0902292?

A: Yes. Both components are 50A, 277V AC, 2-pole, lever-actuated thermal magnetic circuit breakers on DIN rail mounts. The 1020012 is the designated substitute and maintains functional equivalence for all AC applications.

Q: What is the difference between the TMC 60 and TMC 7 series?

A: The 0902292 belongs to the TMC 60 series (obsolete), while the 1020012 belongs to the TMC 7 series (active). Both series employ identical thermal magnetic protection principles and DIN rail mounting. The TMC 7 series represents the current product line with enhanced compliance certifications.

Q: Does the 1020012 add any new capabilities?

A: The 1020012 includes 125V DC voltage rating capability, which the 0902292 does not specify. This addition does not affect AC-only applications but provides flexibility for mixed AC/DC circuit designs.

Q: Are there packaging differences?

A: The 1020012 is supplied in box packaging. The original 0902292 packaging specification is not detailed. Verify packaging requirements for your procurement process.

Q: What is the Moisture Sensitivity Level difference?

A: The 0902292 lists MSL as Not Applicable, while the 1020012 is rated MSL 1 (Unlimited). This indicates the 1020012 has no moisture sensitivity restrictions during storage and handling.

Q: Are both components RoHS compliant?

A: Yes. The 0902292 is RoHS Compliant, and the 1020012 is ROHS3 Compliant, representing an updated compliance standard. Both meet RoHS requirements.
