Circuit Breaker Thermal Magnetic 3DU10L Equivalent & Substitute Parts

Part Overview

The 3DU10L is a three-pole thermal magnetic circuit breaker rated for 10A at 480V AC/DC with lever actuation and DIN rail mounting. Manufactured by Altech Corporation, this component is classified as obsolete. Due to its obsolete status, identifying equivalent substitute parts is essential for system maintenance, repair, and replacement applications where continued availability cannot be guaranteed.

Key Parameters

Substitute Part Grouping Explanation

The 3D10UL qualifies as a direct substitute for the 3DU10L based on the following matching parameters:

• Identical breaker type: Thermal Magnetic
• Identical current rating: 10A
• Identical voltage rating: 480V AC
• Identical number of poles: 3
• Identical actuator type: Lever
• Identical mounting type: DIN Rail
• Identical approval agencies: CE, cULus, UL489
• Identical RoHS compliance: ROHS3 Compliant

The primary difference is the series designation (UL versus L) and product status (Active versus Obsolete). The 3D10UL maintains all functional and electrical specifications required for direct replacement in applications currently using the 3DU10L.

Parameter Comparison

Engineering Selection Recommendations

The 3D10UL is the direct equivalent substitute for the obsolete 3DU10L. Selection of the 3D10UL is supported by:

• Active product status ensuring continued availability and supply chain reliability
• Identical electrical specifications (10A, 480V AC, 3-pole thermal magnetic operation)
• Identical mechanical specifications (lever actuation, DIN rail mounting)
• Identical regulatory compliance (CE, cULus, UL489 certifications)
• Identical RoHS3 compliance status

No functional or performance degradation occurs when replacing 3DU10L units with 3D10UL units in existing installations.

Frequently Asked Questions (FAQ)

Q: Can the 3D10UL directly replace the 3DU10L without modification?

A: Yes. The 3D10UL is a direct substitute with identical electrical and mechanical specifications. No circuit modifications or mechanical adaptations are required.

Q: What is the difference between the L and UL series designations?

A: The series designation reflects internal product line organization within Altech Corporation. Both series maintain identical functional specifications for this 10A, 480V, three-pole thermal magnetic breaker.

Q: Are the approval certifications identical?

A: Yes. Both parts carry CE, cULus, and UL489 certifications, ensuring compliance with the same regulatory standards.

Q: Why is the 3DU10L classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 3D10UL represents the current active equivalent within the Altech product portfolio.

Q: Does packaging differ between these parts?

A: The 3DU10L packaging is unspecified in available documentation. The 3D10UL is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 3DU10L and 3D10UL meet ROHS3 compliance requirements.
