Phoenix Contact 0902328 Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 0902328 is a thermal magnetic circuit breaker rated at 1A, 480V AC, with a 3-pole lever actuator designed for DIN rail mounting. This component is classified as obsolete, making identification of suitable substitute parts essential for system maintenance and component replacement in existing installations.

The obsolete status necessitates sourcing equivalent alternatives that maintain functional compatibility with the original circuit protection requirements while meeting current availability and compliance standards.

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 1A
• Breaker Type: Must be thermal magnetic
• Number of Poles: Must be 3-pole configuration
• Actuator Type: Must be lever-operated
• Mounting Type: Must be DIN rail compatible

The substitute part Phoenix Contact 1020015 satisfies all mandatory functional parameters. However, the voltage rating differs: the original part is rated for 480V AC, while the substitute is rated for 277V AC. This voltage differential represents a critical distinction that must be evaluated based on the specific application circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1020015 is an active product with current manufacturing status and ROHS3 compliance, providing supply chain continuity for the obsolete 0902328. Both components share identical current rating, pole configuration, actuator type, and mounting methodology.

The voltage rating difference (480V versus 277V) is the primary technical distinction. Selection of the 1020015 as a substitute is appropriate only when the application circuit operates at 277V AC. For circuits requiring 480V AC operation, the voltage rating differential must be resolved through alternative sourcing or circuit redesign evaluation.

Both parts carry equivalent ECCN and HTSUS classifications, indicating consistent regulatory treatment for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can the 1020015 directly replace the 0902328 in a 480V circuit?

A: No. The 1020015 is rated for 277V AC maximum, while the original 0902328 is rated for 480V AC. Direct substitution in a 480V circuit would exceed the voltage rating of the substitute component.

Q: Are the mechanical mounting dimensions identical between these parts?

A: Both components use DIN rail mounting with 3-pole lever actuators. Mechanical compatibility for DIN rail installation is maintained. Specific dimensional verification should reference manufacturer datasheets for exact mounting specifications.

Q: What is the significance of the series change from TMC 60 to TMC 7?

A: The series designation indicates different product generations within the Phoenix Contact thermal magnetic breaker portfolio. The TMC 7 series represents a current-generation product line, while TMC 60 is obsolete. Functional parameters for the 1A, 3-pole, lever-actuated configuration remain consistent across series designations.

Q: Are there compliance differences between RoHS and ROHS3?

A: ROHS3 represents the current RoHS Directive implementation with updated substance restrictions. Both designations indicate lead-free and restricted hazardous substance compliance. The 1020015 meets the more recent ROHS3 standard.

Q: What packaging format is supplied with the 1020015?

A: The 1020015 is supplied in box packaging, compared to the original part specification which did not specify packaging format.
