Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 0902412 is determined by the following critical parameters:

• Current Rating: 25A (must match exactly)
• Breaker Type: Thermal Magnetic (must match exactly)
• Number of Poles: 3 (must match exactly)
• Mounting Type: DIN Rail (must match exactly)
• Actuator Type: Lever (must match exactly)
• Voltage Rating - AC: Acceptable range determined by application requirements

The substitute part Phoenix Contact 1020029 maintains identical specifications for current rating, breaker type, pole configuration, mounting type, and actuator type. The voltage rating differs (277V versus 480V), which restricts direct substitution to applications operating at the lower voltage level.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1020029 is an active product with current manufacturing status and ROHS3 compliance, making it suitable for new designs and replacement applications. However, the voltage rating difference (277V versus 480V) restricts its use to systems operating at the lower voltage specification. Direct substitution is only applicable in 277V AC applications. For 480V AC systems, alternative 480V-rated thermal-magnetic 25A three-pole DIN rail breakers from Phoenix Contact or other manufacturers must be sourced.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1020029 replace the 0902412 in all applications?

A: No. The 1020029 is rated for 277V AC, while the 0902412 is rated for 480V AC. Substitution is only valid for applications operating at 277V AC. Voltage mismatch will result in improper breaker operation and potential safety hazards.

Q: Why is the 0902412 obsolete?

A: The 0902412 belongs to the TMC 60 series, which has been superseded by newer Phoenix Contact breaker series. The active substitute 1020029 from the TMC 7 series represents the current product line.

Q: Are there mechanical compatibility concerns between the 0902412 and 1020029?

A: Both components share identical mechanical specifications: three-pole configuration, DIN rail mounting, and lever actuation. Physical installation compatibility is maintained.

Q: What compliance certifications apply to both parts?

A: The 0902412 is RoHS Compliant. The 1020029 is ROHS3 Compliant and REACH Unaffected, representing updated regulatory compliance standards.

Q: What is the packaging difference?

A: The 0902412 packaging specification is not provided. The 1020029 is supplied in Box packaging.
