Circuit Breaker Thermal Magnetic 2DU15L Equivalent & Substitute Parts

Part Overview

The Altech Corporation 2DU15L is a thermal magnetic circuit breaker rated for 15A at 480V AC and 250V DC, designed for DIN rail mounting with lever actuation. This component is discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for system maintenance, repair, and new installations where this specific model is no longer readily available through primary distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2DU15L is determined by strict equivalence across the following critical parameters:

• Current Rating: 15A (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 (certification compliance required)

The substitute part 2D15UL meets all critical electrical and mechanical parameters. While the 2D15UL operates at 480V AC without a specified DC voltage rating in the provided data, it maintains thermal magnetic operation, 15A current capacity, DIN rail mounting, lever actuation, and dual-pole configuration with identical regulatory approvals.

Parameter Comparison

Engineering Selection Recommendations

The 2D15UL serves as a direct functional equivalent to the discontinued 2DU15L. Both components share identical electrical ratings (15A, 480V AC), mechanical configuration (DIN rail, lever actuation, 2-pole), and regulatory certifications (CE, cULus, UL489). The 2D15UL is currently active in inventory with 1074 units available, providing supply continuity for applications previously specified with the 2DU15L.

Selection of the 2D15UL is appropriate for all applications where the 2DU15L was originally specified, provided the DC voltage rating differential (250V DC for 2DU15L versus unspecified for 2D15UL) does not constitute a system requirement. For DC-specific applications, verification of the 2D15UL's DC operating capability against application requirements is necessary.

Frequently Asked Questions (FAQ)

Q: Can the 2D15UL directly replace the 2DU15L in existing installations?

A: Yes, the 2D15UL is electrically and mechanically equivalent. Both are 15A thermal magnetic breakers with 480V AC rating, DIN rail mounting, lever actuation, and dual-pole configuration. Both carry identical regulatory approvals (CE, cULus, UL489). Physical form factor and terminal compatibility are consistent between the two models.

Q: What is the difference between the 2DU15L and 2D15UL series designations?

A: The 2DU15L belongs to the L series, while the 2D15UL belongs to the UL series. Both are manufactured by Altech Corporation and share the same base product number (2D15). The series designation reflects internal product line organization but does not affect functional equivalence for the specified electrical and mechanical parameters.

Q: Is the 2D15UL suitable for DC applications?

A: The 2DU15L explicitly supports 250V DC operation. The 2D15UL's DC voltage rating is not specified in the available data. For applications requiring DC operation, confirmation of the 2D15UL's DC capability is necessary before substitution.

Q: What is the packaging difference between these parts?

A: The 2DU15L is supplied in standard packaging, while the 2D15UL is supplied in bulk packaging. This distinction affects order quantities and handling but does not impact electrical or mechanical performance.

Q: Are both parts RoHS compliant?

A: Yes, both the 2DU15L and 2D15UL are ROHS3 compliant. Both also maintain REACH Unaffected status and carry EAR99 ECCN classification.
