Circuit Breaker Thermal Magnetic 4A 277VAC Phoenix Contact 0902205

Part Overview

The Phoenix Contact 0902205 is a thermal magnetic circuit breaker rated for 4A at 277V AC, designed for DIN rail mounting with lever actuation and 2-pole configuration. This component is classified as obsolete, making it necessary to identify functionally equivalent alternatives from the active product lineup that maintain the same electrical and mechanical specifications for direct replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of thermal magnetic circuit breakers is determined by equivalence across the following critical parameters: current rating (4A), AC voltage rating (277V), mounting configuration (DIN rail), pole count (2), and actuator type (lever). The substitute part Phoenix Contact 1019997 maintains all these core electrical and mechanical specifications while transitioning from the obsolete TMC 60 series to the active TMC 7 series. The addition of 125V DC rating capability in the substitute part does not restrict its use in AC-only applications and represents an enhancement rather than a deviation from the original specification.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1019997 is the direct substitute for the obsolete 0902205. Both components share identical electrical ratings (4A, 277V AC), mechanical configuration (2-pole, lever-actuated, DIN rail mount), and functional classification (thermal magnetic protection). The substitute part carries active product status with ROHS3 compliance, providing continued availability and regulatory alignment. The extended DC voltage rating of the substitute part does not affect AC circuit applications and represents current manufacturing standards for the TMC 7 series.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1019997 directly replace 0902205 in existing installations? A: Yes. Both parts are rated for 4A at 277V AC with identical 2-pole lever-actuated DIN rail configurations. The electrical and mechanical interfaces are equivalent.

Q: What is the significance of the 125V DC rating on the substitute part? A: The 1019997 includes DC voltage capability that the original 0902205 does not specify. This does not restrict its use in AC-only circuits and reflects current product design standards.

Q: Why is the original part classified as obsolete? A: The 0902205 belongs to the TMC 60 series, which has been superseded by the TMC 7 series. The 1019997 represents the current generation equivalent with maintained electrical specifications.

Q: Are there packaging differences between these parts? A: The 0902205 is specified with standard packaging, while the 1019997 is supplied in box packaging. Both are suitable for component-level installation on DIN rail systems.

Q: Do both parts meet current regulatory requirements? A: The 0902205 is RoHS Compliant. The 1019997 meets ROHS3 Compliant standards, representing current regulatory alignment for new procurement.
