Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 4420.0482 is determined by the following critical parameters:

• Current Rating: Must be 5A
• Mounting Type: Must be DIN Rail
• Breaker Type: Must be Thermal Magnetic
• Number of Poles: Must be 3
• Actuator Type: Must be Lever
• Voltage Compatibility: AC voltage must support minimum 277V; DC voltage must support minimum 65V

Two substitute parts meet these criteria: Phoenix Contact 1020019 (TMC 7 series) and Phoenix Contact 2907611 (TMC 8 series). Both are active products with identical current ratings, pole configurations, and mounting specifications. The primary distinction lies in voltage ratings, with 2907611 offering higher voltage capability (480V AC / 125V DC) compared to 1020019 (277V AC).

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1020019 (TMC 7 Series) provides direct voltage compatibility with the original SCHURTER 4420.0482, supporting 277V AC operation. This substitute maintains identical electrical specifications for the primary application voltage while offering active product status and ROHS3 compliance. The TMC 7 series is suitable for applications requiring exact voltage matching to the original design.

Phoenix Contact 2907611 (TMC 8 Series) offers enhanced voltage ratings (480V AC / 125V DC) and is appropriate for applications where higher voltage capability is beneficial or required. This substitute provides greater design margin and flexibility for future system modifications. The TMC 8 series maintains ROHS3 compliance and active product status.

Both substitutes carry identical current ratings, pole configurations, and mounting specifications. Selection between them depends on system voltage requirements and design headroom considerations.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1020019 directly replace SCHURTER 4420.0482 in existing installations?

A: Yes. Both components share identical current ratings (5A), pole count (3), mounting type (DIN Rail), and actuator type (Lever). The 1020019 supports the required 277V AC voltage. Physical form factor and DIN rail compatibility are equivalent.

Q: What is the primary difference between the two Phoenix Contact substitutes?

A: Phoenix Contact 1020019 (TMC 7) is rated for 277V AC, matching the original SCHURTER specification. Phoenix Contact 2907611 (TMC 8) is rated for 480V AC and 125V DC, providing higher voltage capability. Both are 5A, 3-pole thermal magnetic breakers with lever actuation.

Q: Is DC voltage rating critical for substitution?

A: DC voltage rating must meet or exceed the system requirement. The original SCHURTER 4420.0482 is rated for 65V DC. Phoenix Contact 1020019 does not specify DC voltage rating. Phoenix Contact 2907611 is rated for 125V DC, exceeding the original specification.

Q: Are packaging differences significant?

A: Both Phoenix Contact substitutes are supplied in Box packaging. Packaging does not affect electrical or mechanical compatibility for DIN rail mounted circuit breakers.

Q: Do all three breakers carry equivalent safety certifications?

A: All three components are ROHS3 compliant. The original SCHURTER 4420.0482 carries CSA, EN, GB, IEC, and UL certifications. Specific certification details for Phoenix Contact substitutes should be verified against system requirements and regional standards.
