Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for thermal magnetic circuit breakers is determined by strict equivalence across electrical and mechanical parameters. The primary criteria are:

• Current Rating: 8A (exact match required)
• Voltage Rating - AC: 277V (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Number of Poles: 1 (exact match required)
• Actuator Type: Lever (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)

The substitute parts identified maintain these core parameters. Variations in DC voltage rating (65V vs. 60V) and manufacturer origin represent acceptable deviations within the scope of component substitution for this product category, provided AC voltage and current ratings remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

SCHURTER 4420.0228 serves as the parametric equivalent, sharing identical electrical ratings, mechanical configuration, and regulatory certifications with the primary part. Both components are obsolete status, indicating limited availability through standard distribution channels.

Phoenix Contact 2907565 functions as a similar substitute with active product status, ensuring ongoing availability and supply chain continuity. The DC voltage rating differential (60V versus 65V) represents a minor deviation that does not compromise functional compatibility in standard 277V AC applications. This component carries equivalent RoHS3 compliance and maintains the same current, AC voltage, mounting, and actuation specifications.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 4420.0228 directly replace SCHURTER 4420.0714?

A: Yes. Both components share identical electrical ratings (8A, 277V AC, 65V DC), thermal magnetic operation, single-pole configuration, lever actuation, and DIN rail mounting. Regulatory certifications are equivalent.

Q: Is Phoenix Contact 2907565 a suitable substitute?

A: Yes. The component maintains all critical parameters: 8A current rating, 277V AC voltage, thermal magnetic operation, single-pole design, lever actuation, and DIN rail mounting. The DC voltage rating is 60V instead of 65V, which does not affect AC circuit protection performance.

Q: What is the significance of the product status difference?

A: SCHURTER 4420.0714 and 4420.0228 are both obsolete, indicating discontinued production. Phoenix Contact 2907565 is active, meaning it remains in current production and is available through standard distribution channels.

Q: Are packaging differences relevant to substitution?

A: Packaging (individual vs. bulk vs. box) affects logistics and inventory management but does not impact electrical or mechanical compatibility. Component functionality remains unchanged regardless of packaging format.

Q: Do all substitutes meet the same regulatory standards?

A: SCHURTER components carry identical certifications (CSA C22.2 No 14, CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077, UL508). Phoenix Contact 2907565 maintains ROHS3 compliance and equivalent regulatory standing for thermal magnetic circuit breaker applications.
