Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 4420.0459 is determined by the following critical parameters:

• Current Rating: 6A (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Number of Poles: 2 (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Actuator Type: Lever (exact match required)
• Voltage Rating: DC 360V or higher AC/DC rated equivalent
• Regulatory Compliance: Certifications supporting the intended application

The Altech Corporation 2C6UL meets the core functional and mechanical requirements, sharing identical current rating, breaker type, pole configuration, mounting standard, and actuation method. The substitute part operates at 480V AC/DC, providing voltage margin above the original 360V DC specification.

Parameter Comparison

Engineering Selection Recommendations

The Altech 2C6UL serves as a direct functional substitute for the obsolete SCHURTER 4420.0459. Both components share identical current and pole ratings with matching thermal-magnetic protection characteristics and DIN rail form factor. The Altech part carries active product status with current manufacturing support, eliminating supply chain risk associated with the obsolete SCHURTER component.

Regulatory compliance differs between the two parts. The SCHURTER 4420.0459 holds certifications under CSA C22.2 No 14, CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077, and UL508. The Altech 2C6UL carries CE, cULus, and UL489 certifications. Application requirements determine whether the specific certification set of the substitute part aligns with system-level compliance obligations.

The voltage rating differential (360V DC original versus 480V AC/DC substitute) represents a design margin increase. This higher rating does not compromise protection function and supports broader application flexibility.

Frequently Asked Questions (FAQ)

Q: Can the Altech 2C6UL directly replace the SCHURTER 4420.0459 in existing installations?

A: Mechanical and electrical compatibility is confirmed across current rating, pole configuration, mounting standard, and actuation method. Regulatory certification alignment must be verified against system-level compliance requirements before implementation.

Q: What is the significance of the voltage rating difference between 360V DC and 480V AC/DC?

A: The substitute part's higher voltage rating provides operational margin and does not degrade protection performance. The 480V AC/DC rating encompasses the original 360V DC specification.

Q: Why is the SCHURTER 4420.0459 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Altech 2C6UL maintains active production status, ensuring availability for replacement and new applications.

Q: Are there differences in regulatory certifications between these parts?

A: Yes. The SCHURTER part holds CSA, EN, GB, IEC, UL1077, and UL508 certifications. The Altech part carries CE, cULus, and UL489 certifications. Application-specific compliance requirements determine whether the substitute certification set is acceptable.

Q: What packaging is available for the Altech 2C6UL?

A: The Altech 2C6UL is supplied in bulk packaging, consistent with the original SCHURTER component packaging format.
