Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 4420.0926 is determined by the following critical parameters:

• Breaker Type: Thermal Magnetic (required match)
• Current Rating: 30A (required match)
• Mounting Type: DIN Rail (required match)
• Actuator Type: Lever (required match)
• Number of Poles: 1 (required match)
• Voltage Rating: DC 180 V minimum capability (required match or exceed)
• Approval Standards: Compliance with applicable safety certifications

The Altech Corporation 1D30UL meets the core functional and mechanical requirements. While the voltage rating differs (277 V AC/DC versus 180 V DC), the substitute part's higher voltage rating provides equivalent or superior protection capability for the specified 180 V DC application.

Parameter Comparison

Engineering Selection Recommendations

The Altech 1D30UL is the identified substitute for the obsolete SCHURTER 4420.0926. Selection is based on:

• Identical current rating (30A) and pole configuration (1P)
• Matching breaker type (thermal magnetic) and actuation method (lever)
• Identical DIN rail mounting interface
• Active product status with current manufacturing availability
• ROHS3 compliance maintained
• Approval certifications appropriate for industrial control applications (CE, cULus, UL489)

The substitute part's voltage rating specification (277 V AC/DC) is compatible with the original 180 V DC requirement.

Frequently Asked Questions (FAQ)

Q: Can the Altech 1D30UL directly replace the SCHURTER 4420.0926 in existing installations?

A: Yes. Both parts share identical current rating (30A), pole count (1), mounting type (DIN rail), and actuation method (lever). The mechanical and electrical interfaces are equivalent.

Q: What is the significance of the voltage rating difference?

A: The SCHURTER part is rated 180 V DC. The Altech substitute is rated 277 V AC/DC. A higher voltage rating indicates the component can safely operate at the original specification. This represents equivalent or superior capability for the 180 V DC application.

Q: Are the approval certifications equivalent?

A: Both parts carry relevant industrial safety approvals. The SCHURTER part includes UL1077 and UL508 certifications. The Altech part includes cULus and UL489 certifications. Selection should be verified against specific application requirements and regional standards.

Q: Why is the SCHURTER part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Altech 1D30UL is an active product with current manufacturing and inventory availability.

Q: Are there packaging differences?

A: The SCHURTER part is packaged as individual units. The Altech substitute is supplied in bulk packaging. Procurement quantities should be adjusted accordingly.
