Phoenix Contact 0902030 Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 0902030 is a thermal-magnetic circuit breaker rated at 2A with lever actuation, 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 0902030 belongs to the TMC series and provides overcurrent protection through combined thermal and magnetic trip mechanisms. Due to its obsolete status, active equivalent models from the same manufacturer are recommended for new procurement and replacement scenarios.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 0902030 is determined by the following critical parameters:

• Current Rating: 2A (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Actuator Type: Lever (exact match required)
• Number of Poles: 1 (exact match required)
• Manufacturer: Phoenix Contact (same manufacturer preferred for series continuity)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement maintained)

The substitute part Phoenix Contact 1019973 satisfies all critical parameters. This part is from the TMC 7 series, an active product line that maintains functional and mechanical compatibility with the obsolete 0902030 model.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1019973 is the qualified substitute for the obsolete 0902030 circuit breaker. Both components maintain identical functional specifications for current rating, breaker type, mounting configuration, and pole count. The 1019973 is an active product with current manufacturing status, ensuring availability and supply chain continuity.

Both parts carry ROHS3 compliance and maintain identical ECCN and HTSUS classifications, confirming regulatory and trade compliance alignment. The 1019973 provides specified voltage ratings (277 V AC, 60 V DC) that establish operational boundaries for the substitute part in AC and DC applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1019973 directly replace the 0902030 in existing installations?

A: Yes. Both components share identical current ratings (2A), breaker type (thermal-magnetic), mounting method (DIN rail), actuator configuration (lever), and pole count (1). Mechanical and electrical compatibility is established through these matching parameters.

Q: What is the primary reason for substitution?

A: The 0902030 is classified as obsolete. The 1019973 is an active product from the TMC 7 series, providing equivalent functionality with current manufacturing and supply availability.

Q: Are there voltage rating differences between these parts?

A: The 0902030 does not specify voltage ratings in available documentation. The 1019973 is rated for 277 V AC and 60 V DC operation. When replacing the 0902030, confirm that the application voltage does not exceed these ratings.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 0902030 and 1019973 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8536.20.0040.

Q: What packaging is available for the substitute part?

A: The 1019973 is supplied in box packaging. The 0902030 packaging specification is not provided in available data.
