Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 4420.0192 is determined by strict equivalence across the following critical parameters:

• Current Rating: 15A (exact match required)
• Voltage Rating - AC: 277V (exact match required)
• Voltage Rating - DC: 60V minimum (65V DC rated part may be substituted with 60V DC rated equivalent)
• Mounting Type: DIN Rail (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Actuator Type: Lever (exact match required)
• Number of Poles: 1 (exact match required)

The Phoenix Contact 2907638 meets all substitution criteria with equivalent electrical ratings and mechanical form factor, with the exception of DC voltage rating (60V DC versus 65V DC original specification).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2907638 is an active product with equivalent electrical and mechanical specifications to the obsolete SCHURTER 4420.0192. Both components maintain ROHS3 compliance and share identical current ratings, AC voltage ratings, mounting configuration, and actuator type. The DC voltage rating differential (60V versus 65V) represents a 5V reduction in maximum DC operating capability. Selection of the Phoenix Contact substitute is appropriate for applications where the 60V DC rating satisfies system requirements. Both components are certified to equivalent international standards including IEC 60934 and UL1077.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2907638 directly replace the SCHURTER 4420.0192 in all applications?

A: Direct replacement is appropriate when system DC voltage requirements do not exceed 60V. The 15A current rating, 277V AC rating, DIN rail mounting, lever actuation, and single-pole configuration are identical between both components.

Q: What is the significance of the 5V DC voltage rating difference?

A: The SCHURTER original is rated to 65V DC maximum, while the Phoenix Contact substitute is rated to 60V DC maximum. Applications operating at DC voltages between 60V and 65V require verification that the substitute meets system requirements.

Q: Are both components certified to the same standards?

A: Both components comply with ROHS3 requirements and are certified to IEC 60934 and UL1077 standards. Specific approval agency certifications should be verified against system requirements.

Q: What packaging is available for the substitute part?

A: The Phoenix Contact 2907638 is supplied in box packaging, compared to the original SCHURTER component packaging designation.

Q: Is the Phoenix Contact 2907638 currently available?

A: Yes, the Phoenix Contact 2907638 is classified as an active product with inventory availability.
