Phoenix Contact 0902153 Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 0902153 is a thermal-magnetic circuit breaker rated for 63A at 277V AC, designed for DIN rail mounting with lever actuation. This single-pole breaker belongs to the TMC 60 series and is currently classified as obsolete. Due to its discontinued status, identifying compatible substitute components is essential for system maintenance, replacement, and continued operational support. The substitute part maintains equivalent electrical and mechanical specifications while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 0902153 is determined by the following critical parameters:

• Current Rating: 63A (exact match required)
• Voltage Rating - AC: 277V (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Number of Poles: 1 (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Actuator Type: Lever (exact match required)
• Manufacturer: Phoenix Contact (same manufacturer preferred for consistency)

The substitute part 1019992 satisfies all critical electrical and mechanical parameters. While it belongs to the newer TMC 7 series and includes additional DC voltage rating capability (60V DC), these enhancements do not compromise compatibility in AC-only applications. The substitute maintains identical current, AC voltage, pole configuration, mounting method, and actuation mechanism.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1019992 is the qualified substitute for the obsolete 0902153 based on the following engineering criteria:

Electrical Compatibility: Both components share identical current rating (63A), AC voltage rating (277V), pole configuration (1-pole), and thermal-magnetic protection mechanism. The substitute's additional 60V DC rating does not affect AC circuit applications and represents a capability enhancement.

Mechanical Compatibility: Identical DIN rail mounting and lever actuation ensure direct mechanical interchangeability without modification to existing installations.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and safety standards. Both are classified under ECCN EAR99.

Product Status Advantage: The substitute transitions from obsolete to active product status, ensuring long-term availability, continued manufacturer support, and access to current inventory (1019 pieces in stock versus 1038 pieces for the discontinued part).

Frequently Asked Questions (FAQ)

Q: Can the 1019992 directly replace the 0902153 in existing installations?

A: Yes. Both components are single-pole, 63A, 277V AC thermal-magnetic breakers with lever actuation on DIN rail mounting. Electrical and mechanical specifications are identical, enabling direct substitution without circuit modification.

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

A: The 1019992 includes a 60V DC rating, which the original 0902153 does not specify. In AC-only applications, this additional capability is not utilized but does not create incompatibility. The part remains fully functional in 277V AC circuits.

Q: Why is product status important for this substitution?

A: The 0902153 is classified as obsolete, meaning Phoenix Contact no longer manufactures or supports it. The 1019992 is active, ensuring continued availability, manufacturer technical support, and compliance with current standards. Long-term supply chain reliability favors the active substitute.

Q: Are there packaging differences between these parts?

A: The 0902153 is listed with packaging designation "-" (not specified), while the 1019992 is packaged in boxes. Packaging differences do not affect electrical or mechanical performance and relate only to logistics and storage.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the 0902153 and 1019992 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations. Both carry ECCN EAR99 classification.
