Phoenix Contact 0902263 Circuit Breaker Thermal Magnetic 25A Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 0902263 is a thermal-magnetic circuit breaker rated for 25A with lever actuation, designed for DIN rail mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and new installations where original stock is unavailable.

The primary reason for identifying substitute parts is the obsolete product status. Active equivalent models maintain the same core electrical and mechanical specifications while offering improved availability and current manufacturing support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 0902263 is based on the following critical parameters that must remain constant:

• Current Rating: 25A (exact match required)
• Breaker Type: Thermal Magnetic (functional operation principle)
• Number of Poles: 2 (circuit configuration)
• Actuator Type: Lever (mechanical interface)
• Mounting Type: DIN Rail (physical installation compatibility)

The substitute part Phoenix Contact 1020008 satisfies all mandatory substitution criteria. It maintains identical current rating, breaker type, pole configuration, actuation method, and mounting standard. The substitute is from the same manufacturer (Phoenix Contact) and belongs to the related TMC series family, ensuring design compatibility and performance equivalence.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1020008 is the qualified substitute for the obsolete 0902263 model. Selection is based on:

Functional Equivalence: Both components share identical current rating (25A), breaker topology (thermal-magnetic), pole count (2), actuation mechanism (lever), and mounting standard (DIN rail). These parameters define the electrical and mechanical interface requirements for direct substitution.

Product Status: The 1020008 maintains active product status with current manufacturing support, ensuring long-term availability and supply chain reliability compared to the obsolete 0902263.

Compliance: Both parts meet RoHS requirements. The 1020008 carries ROHS3 compliance, representing the current regulatory standard. The substitute also carries REACH Unaffected status, confirming compliance with European chemical regulations.

Voltage Specifications: The 1020008 provides explicit voltage ratings (277 V AC, 125 V DC), offering enhanced specification clarity for system design verification. The original 0902263 does not specify voltage ratings in available documentation.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1020008 directly replace the 0902263 in existing installations?

A: Yes. Both components share identical current rating (25A), thermal-magnetic operation, 2-pole configuration, lever actuation, and DIN rail mounting. Physical and electrical interfaces are compatible for direct substitution.

Q: What is the primary difference between these two models?

A: The 0902263 is obsolete with no active manufacturing, while the 1020008 is an active product from the TMC 7 series. The 1020008 provides explicit voltage ratings (277 V AC, 125 V DC) and current RoHS3 compliance, whereas the 0902263 specifications lack voltage detail.

Q: Are there any compatibility concerns when substituting the 1020008 for the 0902263?

A: No compatibility concerns exist for the specified parameters. Both components are manufactured by Phoenix Contact and maintain identical mechanical and electrical interface standards for DIN rail circuit breaker applications.

Q: Does the packaging differ between these parts?

A: The 1020008 is supplied in Box packaging. The 0902263 packaging specification is not provided in available documentation.

Q: Which part should be selected for new designs?

A: The Phoenix Contact 1020008 should be selected for new designs. It offers active product status, current compliance certifications (ROHS3, REACH Unaffected), and explicit voltage specifications suitable for modern system design requirements.
