Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for thermal-magnetic circuit breakers is determined by matching the following critical parameters:

• Current Rating: 32A (exact match required)
• Voltage Rating - AC: 277V (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Number of Poles: 2 (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Actuator Type: Lever (exact match required)

The substitute part Phoenix Contact 1020010 satisfies all mandatory substitution criteria. This part maintains identical electrical and mechanical specifications while offering active product status and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1020010 is the direct substitute for obsolete part 0902276. Both components share identical core electrical and mechanical specifications: 32A current rating, 277V AC voltage rating, 2-pole thermal-magnetic configuration, DIN rail mounting, and lever actuation.

The substitute part 1020010 provides additional advantages: active product status ensures ongoing availability and manufacturer support, ROHS3 compliance exceeds the RoHS compliance of the original part, and DC voltage rating capability (125V DC) extends application flexibility without compromising AC performance.

Selection of part 1020010 is appropriate for direct replacement in existing installations and new designs requiring 32A thermal-magnetic circuit protection at 277V AC on DIN rail systems.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1020010 directly replace 0902276 in existing installations?

A: Yes. Both parts are thermal-magnetic circuit breakers with identical current rating (32A), AC voltage rating (277V), pole count (2), mounting type (DIN rail), and actuator type (lever). Physical and electrical compatibility is confirmed.

Q: What is the significance of the DC voltage rating on part 1020010?

A: Part 1020010 includes a 125V DC rating, which the original 0902276 does not specify. This additional capability does not affect AC performance and provides expanded application options for systems requiring DC circuit protection.

Q: Why is product status relevant to substitution?

A: The original part 0902276 is obsolete, meaning Phoenix Contact no longer manufactures or supports it. Part 1020010 is active, ensuring continued availability, manufacturer technical support, and compliance with current regulatory standards.

Q: Are there compliance differences between the two parts?

A: Part 0902276 carries RoHS compliance certification. Part 1020010 carries ROHS3 compliance, which represents a more recent and stringent environmental compliance standard. Both parts meet regulatory requirements for their respective product lifecycles.

Q: What packaging is available for the substitute part?

A: Phoenix Contact 1020010 is supplied in box packaging, suitable for standard distribution and installation workflows.
