Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for thermal magnetic circuit breakers is determined by strict equivalence across the following parameters:

• Current Rating: 30A (exact match required)
• Voltage Rating - AC: 277V (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Actuator Type: Lever (exact match required)
• Number of Poles: 1 (exact match required)

The substitute parts are grouped into two categories:

Parametric Equivalent: SCHURTER 4420.0233 matches all critical parameters identically, including DC voltage rating (65V), series designation (AS168XAC1), and approval certifications. This part is from the same manufacturer and product line.

Similar Substitute: Phoenix Contact 2907642 matches all critical parameters with the exception of DC voltage rating (60V versus 65V). This represents a functional alternative where DC voltage tolerance permits the lower rating.

Parameter Comparison

Engineering Selection Recommendations

SCHURTER 4420.0233 is the primary substitute for direct replacement. As a parametric equivalent from the same manufacturer and series, it provides identical electrical and mechanical specifications, including matching DC voltage rating and approval certifications. Both parts carry obsolete status, indicating limited future availability.

Phoenix Contact 2907642 serves as an alternative where system design permits operation at 60V DC instead of 65V DC. This part carries active product status, ensuring continued availability and supply chain reliability. All three parts maintain ROHS3 compliance and share identical AC voltage, current, and mechanical specifications. Selection between these options depends on DC voltage tolerance requirements and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 4420.0233 replace SCHURTER 4420.0624 without modification?

A: Yes. The 4420.0233 is a parametric equivalent with identical current rating (30A), AC voltage (277V), DC voltage (65V), breaker type, mounting configuration, and approval certifications. No circuit modifications are required.

Q: What is the key difference between SCHURTER 4420.0233 and Phoenix Contact 2907642?

A: The primary difference is DC voltage rating: SCHURTER maintains 65V DC while Phoenix Contact is rated 60V DC. Both share identical 30A current rating, 277V AC rating, thermal magnetic operation, DIN rail mounting, and lever actuation. Phoenix Contact carries active product status versus obsolete status for SCHURTER.

Q: Can Phoenix Contact 2907642 be used in applications requiring 65V DC operation?

A: Phoenix Contact 2907642 is rated for 60V DC maximum. Use in circuits exceeding this voltage rating is outside the component's specified operating envelope and is not supported.

Q: Are packaging differences significant for substitution?

A: Packaging (Bulk versus Box) affects logistics and inventory management but does not impact electrical or mechanical compatibility. Component functionality and performance remain identical regardless of packaging format.

Q: Do all three parts meet the same regulatory approvals?

A: SCHURTER 4420.0624 and 4420.0233 share identical approval certifications (CSA C22.2 No 14, CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077, UL508).
