Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 0902056 is determined by the following critical parameters:

• Current Rating: 4A (exact match required)
• Breaker Type: Thermal Magnetic (functional equivalence)
• Mounting Type: DIN Rail (mechanical compatibility)
• Actuator Type: Lever (operational interface)
• Number of Poles: 1 (circuit configuration)
• Regulatory Compliance: ROHS3 and REACH status

The substitute part Phoenix Contact 1019975 satisfies all mandatory substitution criteria. This part belongs to the TMC 7 series and maintains active product status, providing long-term availability and support compared to the obsolete 0902056.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1019975 serves as the direct substitute for the obsolete 0902056. Both components share identical core electrical specifications: 4A thermal-magnetic operation, single-pole configuration, and lever actuation on DIN rail mounting. The substitute part maintains equivalent regulatory compliance through ROHS3 certification and REACH unaffected status.

The 1019975 provides specified voltage ratings (277 V AC, 60 V DC) and active product status, ensuring continued availability and manufacturer support. The transition from the TMC series to the TMC 7 series represents a product line evolution while preserving functional compatibility for 4A circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1019975 directly replace the 0902056 in existing installations?

A: Yes. Both parts are thermal-magnetic circuit breakers with identical current ratings (4A), single-pole configuration, lever actuation, and DIN rail mounting. The 1019975 maintains equivalent regulatory compliance and functional performance for circuit protection applications.

Q: What is the significance of the product status change from Obsolete to Active?
