Circuit Breaker Thermal Magnetic 2DU30L Equivalent & Substitute Parts

Part Overview

The Altech Corporation 2DU30L is a thermal magnetic circuit breaker rated for 30A at 480V AC and 250V DC, designed for DIN rail mounting with lever actuation. This component is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain the same electrical and mechanical specifications for continued system support and replacement applications.

Key Parameters

Substitute Part Grouping Explanation

The 2D30UL qualifies as a direct substitute based on the following matching parameters:

• Current Rating: 30A (identical)
• Voltage Rating - AC: 480V (identical)
• Breaker Type: Thermal Magnetic (identical)
• Mounting Type: DIN Rail (identical)
• Actuator Type: Lever (identical)
• Number of Poles: 2 (identical)
• Approval Agencies: CE, cULus, UL489 (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Base Product Number: 2D30 (same platform)

The primary difference is series designation (UL versus L) and product status (Active versus Discontinued). The 2D30UL maintains full electrical and mechanical compatibility with the 2DU30L.

Parameter Comparison

Engineering Selection Recommendations

The 2D30UL is the qualified substitute for the discontinued 2DU30L. Both components share identical electrical ratings (30A, 480V AC), mechanical configuration (DIN rail, lever actuation, 2-pole), and regulatory certifications (CE, cULus, UL489). The 2D30UL maintains active product status with confirmed inventory availability, making it suitable for direct replacement in applications requiring the 2DU30L specifications.

Frequently Asked Questions (FAQ)

Q: Can the 2D30UL directly replace the 2DU30L in existing installations?

A: Yes. Both components share identical current ratings (30A), AC voltage ratings (480V), mounting configuration (DIN rail), pole count (2), and regulatory approvals (CE, cULus, UL489). The series designation change (UL versus L) does not affect electrical or mechanical compatibility.

Q: What is the difference between the 2DU30L and 2D30UL?

A: The primary differences are series designation and product status. The 2DU30L belongs to the L series and is discontinued. The 2D30UL belongs to the UL series and maintains active status. Both are based on the 2D30 platform and share identical electrical and mechanical specifications.

Q: Are there any packaging differences between these parts?

A: The 2DU30L is specified with standard packaging, while the 2D30UL is supplied in bulk packaging. This does not affect component functionality or performance.

Q: What certifications apply to both parts?

A: Both the 2DU30L and 2D30UL carry CE, cULus, and UL489 approvals, confirming compliance with relevant safety and performance standards for thermal magnetic circuit breakers.

Q: Is the 2D30UL RoHS compliant?

A: Yes. The 2D30UL is ROHS3 compliant, matching the compliance status of the 2DU30L.
