Key Parameters

Substitute Part Grouping Explanation

Substitute identification for the Phoenix Contact 0902331 is based on the following critical parameters that define functional equivalence:

• Current Rating: 2A (exact match required)
• Breaker Type: Thermal Magnetic (protection characteristic must be identical)
• Mounting Type: DIN Rail (physical form factor requirement)
• Actuator Type: Lever (operational interface requirement)
• Number of Poles: 3 (circuit configuration requirement)

The substitute part Phoenix Contact 1020016 maintains equivalence in all functional parameters. The voltage rating difference (277 V AC versus 480 V AC) represents a key distinction that must be evaluated against specific application requirements. Both parts are manufactured by Phoenix Contact and employ identical thermal magnetic protection principles with lever-actuated DIN rail mounting.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1020016 is an active production substitute for the obsolete 0902331. Both components share identical current ratings, breaker type, mounting configuration, and pole count. The substitute maintains RoHS compliance through ROHS3 certification, meeting current regulatory requirements.

The voltage rating differential (277 V versus 480 V) is the primary technical distinction. Selection of the substitute part requires confirmation that the application circuit operates at 277 V AC. For installations requiring 480 V AC operation, the voltage rating of the substitute part is not suitable.

The 1020016 is available in active production status with documented inventory, providing supply chain reliability compared to the obsolete 0902331.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1020016 directly replace the 0902331 in all applications?

A: Direct replacement is possible only in applications where the circuit operates at 277 V AC. The voltage rating difference must be verified against the specific installation requirements. Both parts maintain identical current ratings, thermal magnetic protection characteristics, and DIN rail mounting specifications.
