Circuit Breaker Thermal Magnetic 15A 250VAC - Phoenix Contact 0914728

Part Overview

The Phoenix Contact 0914728 is a single-pole thermal magnetic circuit breaker rated for 15A at 250V AC, designed for DIN rail mounting with lever actuation. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives from active product lines. The thermal magnetic design provides protection against both overload and short-circuit conditions in AC applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 0914728 is based on the following critical parameters that must remain constant or compatible:

• Current Rating: 15A (exact match required)
• Breaker Type: Thermal Magnetic (functional equivalence)
• Number of Poles: 1 (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Actuator Type: Lever (exact match required)
• Voltage Rating - AC: Minimum 250V (equal or higher acceptable)

The E-T-A 2210-T210-K0M1-H131-15A satisfies these substitution criteria. While it features a higher AC voltage rating (480V) and includes DC voltage capability (65V), these represent enhanced specifications that do not compromise compatibility with the original 250V AC application. The thermal magnetic protection mechanism, single-pole configuration, DIN rail mounting, and lever actuation remain functionally identical.

Engineering Selection Recommendations

The E-T-A 2210-T210-K0M1-H131-15A is a direct functional substitute for the obsolete Phoenix Contact 0914728. Selection is supported by:

• Product Status: The E-T-A component is active, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: The E-T-A part holds multiple international certifications (CSA, GB, IEC, UL) that exceed the original component's compliance profile.
• Electrical Compatibility: The 480V AC rating accommodates the original 250V AC application with margin. The addition of 65V DC capability does not affect AC-only circuits.
• Mechanical Compatibility: Identical DIN rail mounting, lever actuation, and single-pole configuration ensure direct installation without modification.

Frequently Asked Questions (FAQ)

Q: Can the E-T-A 2210-T210-K0M1-H131-15A be used in place of the Phoenix Contact 0914728 in a 250V AC circuit?

A: Yes. The E-T-A component is rated for 480V AC, which exceeds the 250V AC requirement. The 15A current rating and thermal magnetic protection mechanism are identical. Direct substitution is electrically and mechanically compatible.

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

A: A higher voltage rating indicates the component can safely operate at elevated voltages without degradation. In a 250V AC application, the 480V rating provides operational margin and does not affect performance or safety.

Q: Does the DC voltage rating of the E-T-A part affect its use in AC-only applications?

A: No. The DC rating is an additional capability. In AC-only circuits, only the AC voltage rating applies. The presence of a DC rating does not compromise AC operation.

Q: Are the certifications on the E-T-A part relevant for this substitution?

A: Yes. The E-T-A component holds CSA, GB, IEC, and UL certifications, which provide broader regulatory acceptance than the original part. These certifications support compliance in multiple markets and applications.

Q: What packaging is available for the substitute part?

A: The E-T-A 2210-T210-K0M1-H131-15A is supplied in bulk packaging, with 731 units currently in stock.
