Circuit Breaker Thermal Magnetic 2DU2L - Equivalent & Substitute Parts

Part Overview

The Altech Corporation 2DU2L is a thermal magnetic circuit breaker rated for 2A at 480V AC and 250V DC, designed for DIN Rail mounting with lever actuation. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and component sourcing. The 2DU2L remains in inventory stock (838 pcs), but its discontinued status necessitates evaluation of active substitute models to ensure long-term availability and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2DU2L is determined by strict equivalence across the following critical parameters:

• Current Rating: 2A (exact match required)
• Voltage Rating - AC: 480V (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: 2 (exact match required)
• Approval Agencies: CE, cULus, UL489 (compliance maintained)

The 2D2UL meets all substitution criteria. While the 2D2UL does not specify a DC voltage rating in the provided data, it maintains identical AC voltage rating, current rating, breaker topology, mounting configuration, and regulatory approvals. Both components are manufactured by Altech Corporation and comply with ROHS3 standards.

Parameter Comparison

Engineering Selection Recommendations

The 2D2UL is the designated substitute for the obsolete 2DU2L based on functional and regulatory equivalence. The 2D2UL maintains active product status with Altech Corporation, ensuring continued availability and supply chain support. Both components carry identical regulatory approvals (CE, cULus, UL489) and ROHS3 compliance, confirming suitability for applications requiring these certifications.

The 2D2UL is available in bulk packaging with 1046 pcs in current inventory stock, providing immediate sourcing capability. Selection of the 2D2UL eliminates obsolescence risk while preserving all critical electrical and mechanical specifications required for direct replacement in 2A, 480V AC DIN Rail thermal magnetic circuit breaker applications.

Frequently Asked Questions (FAQ)

Q: Can the 2D2UL directly replace the 2DU2L in existing installations?

A: Yes. Both components share identical current rating (2A), AC voltage rating (480V), breaker type (thermal magnetic), DIN Rail mounting, lever actuation, pole configuration (2-pole), and regulatory approvals (CE, cULus, UL489). The 2D2UL is the designated substitute for the obsolete 2DU2L.

Q: What is the difference between the 2DU2L and 2D2UL?

A: The primary difference is product status. The 2DU2L is obsolete, while the 2D2UL is active. The 2D2UL is manufactured under the UL series designation, whereas the 2DU2L belongs to the L series. All functional electrical and mechanical parameters remain equivalent.

Q: Does the 2D2UL support DC voltage operation?

A: The 2D2UL specification provided does not include a DC voltage rating. The 2DU2L is rated for 250V DC. Applications requiring DC voltage operation should be evaluated against the complete 2D2UL technical documentation.

Q: Are both components RoHS compliant?

A: Yes. Both the 2DU2L and 2D2UL are ROHS3 compliant and carry identical regulatory approvals (CE, cULus, UL489).

Q: What packaging options are available for the 2D2UL?

A: The 2D2UL is supplied in bulk packaging with 1046 pcs currently in stock inventory.
