Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 4420.0808 is determined by the following critical parameters:

• Current Rating: 15A (exact match required)
• Mounting Type: DIN Rail (form factor requirement)
• Actuator Type: Lever (operational interface requirement)
• Number of Poles: 3 (circuit configuration requirement)
• Breaker Type: Thermal Magnetic (protection mechanism requirement)

The Phoenix Contact 2907618 qualifies as a substitute based on matching all critical parameters. While the voltage ratings differ (480V AC / 125V DC versus 360V DC), the substitute operates at higher voltage ratings, making it suitable for applications where the original part's voltage specification is not exceeded. Both components maintain identical current handling capacity, mounting configuration, and control interface.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2907618 is an active product with current manufacturing status, providing supply continuity for applications requiring thermal magnetic circuit protection at 15A with three-pole DIN rail configuration. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

Selection of the substitute should be based on system voltage requirements. The original SCHURTER component specifies 360V DC operation, while the Phoenix Contact alternative provides 480V AC and 125V DC ratings. Application of the substitute is appropriate where system voltage does not exceed the substitute's rated specifications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2907618 directly replace the SCHURTER 4420.0808?

A: Direct replacement is possible when the application voltage requirements do not exceed the substitute's ratings. The Phoenix Contact component provides equivalent current handling (15A), identical mounting configuration (DIN rail), and matching pole count (3-pole). Verify that your system voltage operates within 480V AC or 125V DC limits.

Q: What are the critical matching parameters for this substitution?

A: Current rating (15A), mounting type (DIN rail), actuator type (lever), number of poles (3), and breaker type (thermal magnetic) must remain constant. Voltage ratings may differ provided the substitute's ratings are not exceeded by the application.

Q: Why is the original part listed as obsolete?

A: The SCHURTER 4420.0808 is no longer in active production. The Phoenix Contact 2907618 represents an active alternative that maintains functional equivalence for new installations and ongoing system maintenance.

Q: Are both components compliant with current regulations?

A: Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What packaging is available for the substitute?

A: The Phoenix Contact 2907618 is supplied in box packaging, with 839 units available in current inventory.
