Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 0902179 is determined by the following critical parameters:

• Current Rating: 1A (exact match required)
• Voltage Rating - AC: 277V (exact match required)
• Breaker Type: Thermal Magnetic (functional equivalence)
• Mounting Type: DIN Rail (mechanical compatibility)
• Actuator Type: Lever (operational interface)
• Number of Poles: 2 (circuit configuration)

The substitute part Phoenix Contact 1019994 satisfies all mandatory substitution criteria. This part maintains identical current and AC voltage ratings, thermal magnetic operation, DIN rail mounting, lever actuation, and 2-pole configuration. The substitute represents an active product from the TMC 7 series, providing continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1019994 is the qualified substitute for the obsolete 0902179. Both components are manufactured by Phoenix Contact and maintain identical electrical specifications for AC operation at 277V, 1A. The substitute part is currently active in production, ensuring long-term availability and supply chain continuity.

The 1019994 provides enhanced compliance through ROHS3 certification and includes DC voltage capability (125V DC) not specified in the original part. These characteristics represent improvements over the original specification without compromising compatibility in AC-only applications.

Selection of the 1019994 is appropriate for direct replacement in existing installations where the 0902179 is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1019994 directly replace the 0902179 in existing systems?

A: Yes. Both parts share identical current rating (1A), AC voltage rating (277V), thermal magnetic operation, DIN rail mounting, lever actuation, and 2-pole configuration. The 1019994 is suitable for direct substitution.

Q: What is the difference between the TMC 60 and TMC 7 series?

A: The original 0902179 belongs to the TMC 60 series, while the substitute 1019994 is from the TMC 7 series. Both series employ thermal magnetic circuit breaker technology with identical electrical ratings for this 1A, 277V application.

Q: Does the substitute part offer any additional capabilities?
