Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2DU25L is determined by strict equivalence across the following critical parameters:

• Current Rating: 25A (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 (minimum compliance required)

The 2D25UL meets all substitution criteria as an active equivalent. Both parts share the same base product number (2D25) and maintain identical electrical and mechanical specifications, with the primary distinction being product status and series designation.

Parameter Comparison

Engineering Selection Recommendations

The 2D25UL is the direct equivalent for the obsolete 2DU25L. Selection of the 2D25UL is supported by:

• Identical electrical specifications (25A, 480V AC)
• Identical mechanical form factor (DIN rail, lever actuation, 2-pole configuration)
• Active product status ensuring ongoing availability and supply chain continuity
• Full compliance with CE, cULus, and UL489 certifications
• ROHS3 compliance maintained across both parts

Frequently Asked Questions (FAQ)

Q: Can the 2D25UL directly replace the 2DU25L in existing installations?

A: Yes. Both parts are manufactured by Altech Corporation with identical current ratings (25A), voltage ratings (480V AC), breaker type (thermal magnetic), mounting configuration (DIN rail), and actuator type (lever). All critical electrical and mechanical parameters match.

Q: What is the primary difference between these two parts?

A: The 2DU25L is classified as obsolete, while the 2D25UL is an active product. The series designation differs (L versus UL), but functional and electrical specifications are equivalent.

Q: Are both parts certified to the same standards?

A: Yes. Both the 2DU25L and 2D25UL carry CE, cULus, and UL489 approvals, ensuring compliance with the same regulatory requirements.

Q: Is the 2D25UL available in the same packaging as the 2DU25L?

A: The 2D25UL is supplied in bulk packaging. Packaging configuration should be verified against specific procurement requirements.

Q: Are there any voltage or current rating differences between these parts?

A: No. Both parts are rated for 25A at 480V AC. The 2DU25L includes a 250V DC rating; this specification is not listed for the 2D25UL and should be confirmed if DC operation is required.
