Frequently Asked Questions (FAQ)

Q: Can the E-T-A 2210-T220-K0F2-H231-0.4A directly replace the Phoenix Contact 0914934 in existing installations?

A: Yes. Both parts share identical current ratings (400mA), breaker type (thermal magnetic), mounting interface (DIN rail), actuator type (lever), and pole configuration (2-pole). The mechanical and electrical interfaces are compatible.

Q: What is the significance of the voltage ratings specified for the E-T-A part?

A: The E-T-A substitute is rated for 480V AC and 65V DC operation. The original Phoenix Contact part does not specify voltage ratings in the available documentation. The E-T-A ratings define the maximum voltage at which the 400mA protection function operates correctly.

Q: Why is the Phoenix Contact 0914934 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The E-T-A 2210-T220-K0F2-H231-0.4A is an active product, providing a path forward for system maintenance and new designs.

Q: Are there packaging differences between these parts?

A: The Phoenix Contact part is listed with standard packaging, while the E-T-A substitute is supplied in bulk packaging. Both are suitable for DIN rail installation.

Q: What certifications apply to the substitute part?

A: The E-T-A 2210-T220-K0F2-H231-0.4A holds CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077 certifications, covering North American and international safety requirements.
