Key Parameters

Substitute Part Grouping Explanation

The E-T-A 2210-T220-K0F2-H231-0.4A qualifies as a functional substitute based on the following critical parameters:

• Current Rating Match: Both parts rated at 400mA
• DC Voltage Match: Both rated at 65V DC
• Breaker Technology: Both employ thermal magnetic protection
• Mounting Configuration: Both use DIN rail mounting
• Pole Configuration: Both are 2-pole devices
• Compliance: Both are RoHS compliant

The substitute part operates at 480V AC versus the original 250V AC rating, representing an upgrade in AC voltage capability suitable for higher-voltage applications while maintaining compatibility in lower-voltage circuits.

Parameter Comparison

Engineering Selection Recommendations

The E-T-A 2210-T220-K0F2-H231-0.4A serves as the primary substitute for the obsolete Phoenix Contact 0914756. Selection is justified by:

• Electrical Equivalence: Identical current and DC voltage ratings ensure protection characteristics remain unchanged in existing circuits
• Active Product Status: The substitute maintains current manufacturing and supply chain support
• Enhanced Compliance: ROHS3 compliance and multiple international certifications (CSA, GB, IEC, UL) provide broader regulatory acceptance
• Mechanical Compatibility: DIN rail mounting and 2-pole configuration enable direct installation in existing enclosures

The actuator type difference (automatic reset versus lever) represents a functional distinction requiring circuit design review. Automatic reset operation provides self-recovery capability, while lever actuation requires manual intervention. Application requirements determine whether this difference impacts system operation.

Frequently Asked Questions (FAQ)

Q: Can the E-T-A 2210-T220-K0F2-H231-0.4A directly replace the Phoenix Contact 0914756 in all applications?

A: Direct mechanical and electrical replacement is possible for circuits operating at or below 250V AC and 65V DC. The higher AC voltage rating of the substitute (480V) does not prevent operation in lower-voltage circuits. The actuator type difference must be evaluated against application requirements for reset behavior.

Q: What is the significance of the 480V AC rating on the substitute part?

A: The E-T-A part is rated for higher AC voltage operation than the original. This represents an upgrade in capability and does not restrict use in 250V AC circuits. The part will function correctly across its entire rated voltage range.

Q: Are there packaging differences between these parts?

A: The Phoenix Contact 0914756 is specified with standard packaging, while the E-T-A 2210-T220-K0F2-H231-0.4A is supplied in bulk packaging. Both are suitable for DIN rail installation without modification.

Q: What certifications apply to the substitute part?

A: The E-T-A 2210-T220-K0F2-H231-0.4A holds certifications including CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077, providing compliance for North American, European, and international markets.

Q: How do the reset mechanisms differ?

A: The original part features automatic reset, which restores operation without manual intervention after a fault condition clears. The substitute uses lever actuation, requiring manual reset after a trip event. System design must accommodate this operational difference.
