Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 0902344 is determined by the following critical parameters that must align between the original and substitute component:

Mandatory Matching Parameters:

• Breaker Type: Thermal Magnetic
• Current Rating: 3A
• Number of Poles: 3
• Mounting Type: DIN Rail
• Actuator Type: Lever

Voltage Consideration: The original part operates at 480 V AC. Substitute part 1020017 operates at 277 V AC, representing a different voltage class. This voltage difference is a material distinction that affects circuit compatibility and must be evaluated against the specific application requirements.

Compliance & Status: The original part is RoHS Compliant. The substitute part is ROHS3 Compliant, representing an updated compliance standard. Both parts maintain EAR99 ECCN classification.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1020017 shares identical functional characteristics with the 0902344 in terms of breaker type, current rating, pole configuration, mounting interface, and actuation method. Both components are manufactured by Phoenix Contact and maintain compliance with applicable standards.

The primary distinction is the voltage rating: the original part is rated for 480 V AC operation, while the substitute is rated for 277 V AC operation. This voltage difference is a critical parameter that determines circuit compatibility. Selection of the 1020017 as a substitute is valid only in applications where the circuit voltage is 277 V AC.

The 1020017 holds active product status, ensuring ongoing availability and support, whereas the 0902344 is obsolete. The 1020017 meets ROHS3 compliance, representing current regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1020017 directly replace the 0902344 in all applications?

A: Direct replacement is valid only if the circuit voltage is 277 V AC. The 0902344 is rated for 480 V AC operation. Voltage mismatch between the component rating and circuit voltage will result in improper operation and potential safety hazards.

Q: What are the core compatibility criteria for substituting the 0902344?

A: Any substitute must maintain: 3A current rating, 3-pole configuration, thermal magnetic protection type, DIN rail mounting, and lever actuation. Voltage rating must match the application circuit voltage.

Q: Why is the 0902344 listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by Phoenix Contact. The 1020017 represents an active alternative within the Phoenix Contact product line.

Q: Does the packaging difference affect compatibility?

A: Packaging (Box for 1020017 versus unspecified for 0902344) affects logistics and storage but does not impact electrical or mechanical compatibility in the installed application.

Q: Are there compliance differences between the two parts?

A: Both parts maintain EAR99 ECCN classification. The 1020017 is ROHS3 Compliant, representing updated compliance standards compared to the RoHS Compliant 0902344. Both meet current regulatory requirements.
