Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 0902441 is determined by the following critical parameters:

• Current Rating: 50A (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 system requirements

The substitute part Phoenix Contact 1020033 maintains identical specifications for current rating, breaker type, pole configuration, mounting type, and actuator type. The voltage rating differs (277V versus 480V), which represents a voltage class reduction and requires system-level compatibility verification.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1020033 serves as an active substitute for the obsolete 0902441 model. Both components share identical electrical and mechanical specifications for current rating, pole configuration, breaker type, and mounting interface. The 1020033 is classified as active product status, ensuring ongoing availability and support.

The primary distinction is the voltage rating: the 1020033 operates at 277V AC compared to the 0902441 at 480V AC. This voltage class difference must be evaluated against the specific application circuit voltage. The 1020033 carries ROHS3 compliance, representing current regulatory alignment compared to the RoHS compliance of the obsolete model.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1020033 directly replace the 0902441 in all applications?

A: Direct replacement is possible only in circuits rated for 277V AC operation. The 1020033 is rated for 277V AC, while the 0902441 is rated for 480V AC. Application voltage must match the breaker voltage rating.

Q: What are the critical parameters that must match for substitution?

A: Current rating (50A), breaker type (thermal-magnetic), pole count (3), mounting type (DIN rail), and actuator type (lever) must all match. Voltage rating must be compatible with the application circuit.

Q: Why is the 0902441 obsolete?

A: The 0902441 is classified as obsolete by Phoenix Contact. The 1020033 represents the active equivalent model within the Phoenix Contact product line.

Q: Are there packaging differences between these models?

A: The 0902441 packaging is listed as standard, while the 1020033 is packaged in boxes. Both are suitable for DIN rail installation.

Q: Do both models meet current compliance standards?

A: Both models are RoHS compliant. The 1020033 carries ROHS3 compliance, representing the current regulatory standard. The 1020033 also carries REACH Unaffected status.
