Key Parameters

Substitute Part Grouping Explanation

Substitution for the SCHURTER 4420.0876 is determined by the following critical parameters:

• Current Rating: 30A (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Actuator Type: Lever (exact match required)
• Number of Poles: 1 (exact match required)
• Voltage Compatibility: The substitute must operate at voltage ratings that encompass or exceed the original 180 V DC specification
• Approval Certifications: Compliance with relevant safety standards (UL, CSA, IEC, EN, GB)

The Altech Corporation 1D30UL meets these substitution criteria with identical current rating, breaker type, mounting configuration, and pole count. The substitute operates at 277 V AC/DC, which provides voltage compatibility for DC applications at 180 V.

Parameter Comparison

Engineering Selection Recommendations

The Altech 1D30UL is an active product suitable for replacing the obsolete SCHURTER 4420.0876 in new designs and system upgrades. Both components share identical functional specifications: 30A thermal magnetic protection, single-pole configuration, lever actuation, and DIN rail mounting.

The substitute carries cULus and UL489 certifications, providing North American compliance. The original part's broader certification portfolio (EN 60934, GB 17701, IEC 60934) should be verified against specific regional requirements for the application. The Altech component's 277 V AC/DC rating accommodates the original 180 V DC specification with adequate voltage margin.

Frequently Asked Questions (FAQ)

Q: Can the Altech 1D30UL directly replace the SCHURTER 4420.0876?

A: Yes, for applications requiring 30A thermal magnetic protection on DIN rail with lever actuation. Both components are single-pole breakers with identical current ratings and mounting configurations. Verify that the substitute's certification profile (CE, cULus, UL489) meets your regional compliance requirements.

Q: What is the voltage compatibility between these two breakers?

A: The SCHURTER 4420.0876 is rated for 180 V DC. The Altech 1D30UL is rated for 277 V AC/DC, which encompasses the original voltage specification. The substitute operates safely at 180 V DC applications.

Q: Why is the original SCHURTER part obsolete?

A: The SCHURTER 4420.0876 is classified as obsolete, indicating it is no longer in active production. The Altech 1D30UL is an active product with current manufacturing and availability.

Q: Are there packaging differences between these parts?

A: The SCHURTER 4420.0876 is packaged as individual units. The Altech 1D30UL is supplied in bulk packaging. Confirm packaging requirements for your procurement process.

Q: Do both breakers meet the same safety standards?

A: The SCHURTER part carries CSA, EN, GB, IEC, and UL certifications. The Altech substitute carries CE, cULus, and UL489 certifications. Both are ROHS3 compliant. Verify that the substitute's certification set aligns with your application's regional and industry standards.
