Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 4420.0228 is determined by strict equivalence across the following critical parameters:

• Breaker Type: Thermal Magnetic protection mechanism
• Current Rating: 8A nominal trip current
• Voltage Rating - AC: 277V minimum
• Voltage Rating - DC: Minimum 60V (the substitute part 2907565 operates at 60V DC, which is within acceptable tolerance for applications designed for 65V DC operation)
• Mounting Type: DIN Rail form factor
• Actuator Type: Lever-operated mechanism
• Number of Poles: Single-pole configuration

The Phoenix Contact 2907565 meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2907565 serves as the direct functional equivalent for the obsolete SCHURTER 4420.0228. Both components maintain identical current and AC voltage ratings, with the substitute operating at 60V DC versus the original 65V DC specification. This 5V differential represents a 7.7% reduction in DC voltage margin and is acceptable for applications where the DC operating voltage does not exceed 60V.

Both parts carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The Phoenix Contact component is currently in active production status, providing supply chain continuity and long-term availability advantages over the obsolete SCHURTER part.

Mechanical and electrical interface compatibility is maintained through identical DIN rail mounting, lever actuation, and single-pole configuration. No additional modifications to mounting hardware or control logic are required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2907565 directly replace the SCHURTER 4420.0228 in existing installations?

A: Yes, the Phoenix Contact 2907565 is mechanically and electrically compatible. Both components share identical current ratings (8A), AC voltage ratings (277V), DIN rail mounting, lever actuation, and single-pole configuration. The DC voltage rating difference (60V versus 65V) does not affect compatibility in applications where DC operating voltage remains at or below 60V.

Q: What is the significance of the DC voltage rating difference between these parts?

A: The SCHURTER 4420.0228 is rated for 65V DC, while the Phoenix Contact 2907565 is rated for 60V DC. This 5V difference means the substitute part should not be used in applications where DC voltage exceeds 60V. For systems operating at or below 60V DC, this difference is not a limiting factor.

Q: Are there any compliance or certification differences between these parts?

A: Both components are ROHS3 compliant and REACH unaffected. The SCHURTER part carries approvals under CSA C22.2 No 14, CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077, and UL508. Verification of Phoenix Contact 2907565 certifications against your specific application requirements is recommended.

Q: Why is the SCHURTER 4420.0228 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Phoenix Contact 2907565 is an active product with ongoing manufacturing support, making it the preferred choice for new designs and replacement applications.

Q: What packaging differences exist between these parts?

A: The SCHURTER 4420.0228 is supplied in bulk packaging, while the Phoenix Contact 2907565 is supplied in box packaging. This affects order quantities and storage considerations but does not impact functional performance or compatibility.
