Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 0915033 is based on the following critical parameters that must align for functional equivalence:

• Current Rating: 20A (exact match required)
• Breaker Type: Thermal Magnetic (functional principle must be identical)
• Mounting Type: DIN Rail (physical form factor requirement)
• Number of Poles: 2 (circuit configuration requirement)
• Actuator Type: Lever (operational interface requirement)
• Voltage Rating - AC: Minimum 250V (equal or higher acceptable)

The identified substitute, E-T-A 2210-T220-K0M1-H231-20A, meets all mandatory substitution criteria. While the E-T-A part supports higher AC voltage (480V) and includes DC voltage capability (65V), these represent enhanced specifications that do not prevent substitution in applications originally designed for 250V AC operation.

Parameter Comparison

Engineering Selection Recommendations

The E-T-A 2210-T220-K0M1-H231-20A serves as a direct functional substitute for the obsolete Phoenix Contact 0915033. Both components share identical current ratings, breaker topology, mounting configuration, and pole count. The E-T-A part maintains active product status with current compliance certifications including CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077, ensuring regulatory alignment for new installations and system upgrades.

The higher voltage specifications of the E-T-A component (480V AC versus 250V AC) provide enhanced operational margin in applications originally specified for 250V AC, with no functional degradation. The addition of DC voltage capability (65V) expands application flexibility without affecting AC-only circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the E-T-A 2210-T220-K0M1-H231-20A directly replace the Phoenix Contact 0915033 in existing installations?

A: Yes. Both components are 2-pole, 20A thermal magnetic DIN rail breakers with lever actuation. The E-T-A part meets or exceeds all electrical specifications of the original component.

Q: What is the significance of the higher voltage rating on the E-T-A substitute?

A: The E-T-A part is rated for 480V AC compared to the original 250V AC specification. This represents an enhanced capability that does not prevent operation in 250V AC circuits. The component will function identically in the original application environment.

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

A: No. The 65V DC rating is an additional capability. In AC-only circuits, this specification is not utilized and does not impact performance.

Q: Are there packaging differences between these components?

A: The Phoenix Contact 0915033 is listed with standard packaging, while the E-T-A 2210-T220-K0M1-H231-20A is supplied in bulk packaging. Both are suitable for DIN rail installation without modification.

Q: What compliance certifications apply to the substitute part?

A: The E-T-A 2210-T220-K0M1-H231-20A holds certifications for CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077, with ROHS3 compliance and REACH unaffected status.
