Circuit Breaker Thermal Magnetic 2DU10L Equivalent & Substitute Parts

Part Overview

The Altech Corporation 2DU10L is a thermal-magnetic circuit breaker rated for 10A at 480V AC/DC with lever actuation and DIN rail mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and component sourcing. The 2DU10L maintains full compliance with CE, cULus, and UL489 standards, and equivalent substitutes must preserve these certifications and electrical characteristics to ensure system integrity and regulatory compliance.

Key Parameters

Substitute Part Grouping Explanation

The 2D10UL qualifies as a direct substitute for the 2DU10L based on the following critical parameters:

• Identical Current Rating: Both parts are rated for 10A continuous operation
• Identical Voltage Rating: Both support 480V AC operation
• Identical Breaker Type: Both employ thermal-magnetic protection mechanisms
• Identical Mounting Configuration: Both mount on DIN rail systems
• Identical Actuator Type: Both feature lever-based manual actuation
• Identical Pole Configuration: Both are 2-pole devices
• Equivalent Certifications: Both hold CE, cULus, and UL489 approvals
• RoHS Compliance: Both meet ROHS3 requirements

The primary distinction between these parts is product status: the 2DU10L is obsolete while the 2D10UL remains active in production, making the latter the preferred selection for new applications and ongoing inventory management.

Parameter Comparison

Engineering Selection Recommendations

The 2D10UL is the direct equivalent for the obsolete 2DU10L. Both parts maintain identical electrical ratings, mechanical configurations, and regulatory certifications. Selection of the 2D10UL is justified by its active production status, ensuring long-term availability and supply chain continuity. Both parts satisfy CE, cULus, and UL489 compliance requirements and are suitable for 480V AC/DC applications requiring 10A thermal-magnetic protection with DIN rail mounting.

Frequently Asked Questions (FAQ)

Q: Can the 2D10UL directly replace the 2DU10L in existing installations?

A: Yes. Both parts share identical electrical ratings (10A, 480V AC), breaker type (thermal-magnetic), mounting configuration (DIN rail), pole count (2), and actuator type (lever). All regulatory certifications are equivalent.

Q: What is the primary reason to transition from 2DU10L to 2D10UL?

A: The 2DU10L is classified as obsolete. The 2D10UL is the active production equivalent, providing assured long-term availability and supply chain support.

Q: Are there packaging differences between these parts?

A: The 2DU10L is supplied with standard packaging, while the 2D10UL is supplied in bulk packaging. This distinction does not affect electrical or mechanical compatibility.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 2DU10L and 2D10UL hold CE, cULus, and UL489 certifications and are ROHS3 compliant.

Q: Are there any voltage or current rating differences?

A: No. Both parts are rated identically at 10A continuous current and 480V AC operation.
