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 63A
• Breaker Type: Must be Thermal Magnetic
• Number of Poles: Must be 3-pole configuration
• Mounting Type: Must be DIN Rail
• Actuator Type: Must be Lever

The substitute part Phoenix Contact 1020036 satisfies all mandatory substitution criteria. 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 thermal-magnetic protection characteristics at the specified current level.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1020036 is an active product with current manufacturing status and ROHS3 compliance certification, providing a viable path for obsolescence management of the 0902454. Both components share identical thermal-magnetic protection characteristics, pole configuration, and DIN rail mounting specifications.

Selection between these parts must account for system voltage requirements. The 0902454 operates at 480V AC, while the 1020036 is rated for 277V AC. Application of the substitute requires verification that the target installation operates at the substitute's rated voltage to ensure proper circuit protection performance.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1020036 directly replace the 0902454 in all applications?

A: Both components share identical current ratings (63A), breaker type (thermal-magnetic), pole configuration (3-pole), and mounting specifications (DIN rail lever actuation). However, the voltage rating differs: 0902454 is rated for 480V AC, while 1020036 is rated for 277V AC. Direct substitution is only appropriate when the installation operates at 277V AC.

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

A: The series designation indicates product family evolution. The TMC 7 series (1020036) represents the active product line, while TMC 60 (0902454) is obsolete. Both series maintain equivalent thermal-magnetic protection characteristics at the specified current rating.

Q: Are there packaging differences between these components?

A: The 0902454 is supplied with standard packaging, while the 1020036 is packaged in a box. Both are suitable for DIN rail installation and do not require special handling considerations.

Q: What compliance certifications apply to each part?

A: The 0902454 carries RoHS Compliant certification. The 1020036 carries ROHS3 Compliant certification and is REACH Affected, representing current regulatory compliance standards.
