Phoenix Contact 0902425 Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 0902425 is a thermal-magnetic circuit breaker rated for 32A at 480V AC, designed for DIN rail mounting with lever actuation. This component is classified as obsolete, necessitating identification of active equivalent models to maintain system functionality and ensure continued availability for replacement and new installations.

Key Parameters

Substitute Part Grouping Explanation

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

• Current Rating (Amps): Must match exactly at 32A
• Breaker Type: Must be thermal-magnetic
• Number of Poles: Must be 3-pole configuration
• Mounting Type: Must be DIN rail compatible
• Actuator Type: Must be lever-operated

The substitute part Phoenix Contact 1020031 satisfies all mandatory electrical and mechanical parameters. While the voltage rating differs (277V AC versus 480V AC), this represents a voltage-specific variant within the same product family, indicating functional equivalence for the thermal-magnetic switching mechanism and current-handling capacity.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1020031 is an active product with current RoHS compliance certification, providing a viable path forward from the obsolete 0902425. Both components share identical current ratings, pole configuration, and mounting architecture. The primary distinction is the voltage rating specification: the substitute operates at 277V AC, whereas the original operates at 480V AC. Selection of the 1020031 requires verification that the system voltage matches the 277V AC specification to ensure proper thermal-magnetic trip characteristics and safe operation within the intended electrical distribution system.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1020031 directly replace the 0902425 in all applications?

A: Direct replacement is contingent upon system voltage compatibility. The 1020031 is rated for 277V AC operation, while the 0902425 is rated for 480V AC. Both share identical current ratings (32A), pole configuration (3-pole), and mounting type (DIN rail). Substitution is valid only when the installation operates at 277V AC.

Q: What are the critical parameters that must match between these two breakers?

A: Current rating (32A), breaker type (thermal-magnetic), number of poles (3), mounting type (DIN rail), and actuator type (lever) must remain constant. Voltage rating is application-specific and must align with the electrical system design.

Q: Why is the 0902425 listed as obsolete?

A: The 0902425 belongs to the TMC 60 series, which has been superseded by newer product lines such as the TMC 7 series (represented by the 1020031). Phoenix Contact has transitioned manufacturing focus to active product lines with current compliance certifications.

Q: Are there packaging differences between these parts?

A: The 0902425 is supplied with standard packaging, while the 1020031 is packaged in a box configuration. Both are suitable for DIN rail installation and do not require special handling beyond standard electronic component storage practices.

Q: What compliance certifications apply to both parts?

A: The 0902425 holds ROHS3 compliance certification. The 1020031 holds RoHS compliance certification. Both are classified as EAR99 under export control regulations and share the same HTSUS code (8536.20.0040), indicating equivalent tariff classification for trade purposes.
