Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 0902409 is determined by the following critical parameters:

• Current Rating: 20A (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 1020028 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 277V AC/DC systems only.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1020028 is an active product with current manufacturing status and ROHS3 compliance certification. Selection of this substitute is appropriate for 277V AC/DC applications requiring a 20A, 3-pole thermal-magnetic circuit breaker with lever actuation on DIN rail mounting.

For 480V AC/DC applications, the 1020028 is not suitable due to voltage rating mismatch. Alternative sources must be consulted to identify active 480V-rated equivalents within the Phoenix Contact product portfolio or from other manufacturers meeting the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1020028 directly replace the 0902409 in all applications?

A: No. While both components share identical current rating, breaker type, pole configuration, mounting type, and actuator type, the voltage ratings differ. The 1020028 is rated for 277V AC/DC, whereas the 0902409 is rated for 480V AC/DC. Direct substitution is only valid for 277V systems.

Q: What is the significance of the series designation change from TMC 60 to TMC 7?

A: The series designation indicates different product generations within the Phoenix Contact thermal-magnetic breaker portfolio. Both series employ identical functional specifications for the parameters provided, but represent different manufacturing lines and design iterations.

Q: Why is the 0902409 classified as obsolete?

A: Obsolete status indicates that Phoenix Contact has discontinued manufacturing and support for this component. The 1020028 represents an active alternative within the current product lineup, though with the voltage rating limitation noted above.

Q: Are there packaging differences between these components?

A: The 0902409 packaging is listed as unspecified in available data. The 1020028 is supplied in box packaging. Verify packaging requirements for your procurement and logistics processes.

Q: What compliance certifications apply to both parts?

A: Both components are RoHS compliant. The 0902409 carries RoHS Compliant certification, while the 1020028 carries ROHS3 Compliant certification. The 1020028 is additionally REACH Affected. Both share the same ECCN (EAR99) and HTSUS (8536.20.0040) classifications.
