Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1020011 qualifies as a functional equivalent based on the following critical parameters:

• Current Rating: Both parts are rated for 40A
• Voltage Rating - AC: Both parts are rated for 277V AC
• Breaker Type: Both employ thermal-magnetic protection
• Mounting Type: Both mount on DIN rail
• Actuator Type: Both feature lever actuation
• Number of Poles: Both are 2-pole configurations

The primary distinction is product status: the 0902289 is obsolete while the 1020011 is active. The 1020011 additionally provides 125V DC rating capability, extending operational flexibility without compromising AC performance specifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1020011 is the appropriate substitute for the obsolete 0902289 based on functional equivalence across all critical electrical and mechanical parameters. The 1020011 maintains identical AC voltage and current ratings while offering enhanced compliance through ROHS3 certification and REACH compliance status. The addition of 125V DC capability in the 1020011 provides operational flexibility for mixed-voltage applications without affecting AC circuit protection performance.

Frequently Asked Questions (FAQ)

Q: Can the 1020011 directly replace the 0902289 in existing installations?

A: Yes. Both parts share identical current rating (40A), AC voltage rating (277V), breaker type (thermal-magnetic), mounting configuration (DIN rail), actuator type (lever), and pole count (2). Physical and electrical compatibility is maintained.

Q: What is the significance of the DC voltage rating on the 1020011?

A: The 1020011 includes a 125V DC rating, enabling its use in DC circuit applications. The 0902289 does not specify DC capability. This additional rating does not affect AC performance and expands application scope.

Q: Why is the 0902289 listed as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. The 1020011, classified as active, represents the current production equivalent and is the recommended selection for new designs and replacements.

Q: Are there compliance differences between these parts?

A: The 0902289 is RoHS Compliant. The 1020011 is ROHS3 Compliant and REACH Affected, reflecting updated regulatory standards. Both meet environmental compliance requirements applicable to their respective production periods.

Q: Does packaging differ between these parts?

A: The 0902289 packaging is not specified. The 1020011 is supplied in box packaging. Verify packaging requirements for your procurement and logistics processes.
