Substitute Part Grouping Explanation

Substitution between the 3DU15L and 3D15UL is based on electrical and mechanical parameter equivalence. Both components share identical specifications across all critical selection criteria: 15A current rating, 480V AC voltage rating, three-pole configuration, lever actuation, and DIN rail mounting. Both maintain compliance with CE, cULus, and UL489 certifications. The primary distinction is product status: the 3DU15L is obsolete while the 3D15UL is active production. Substitution is valid when the following parameters remain constant:

• Current Rating: 15A
• Voltage Rating - AC: 480V
• Number of Poles: 3
• Actuator Type: Lever
• Mounting Type: DIN Rail
• Approval Agency: CE, cULus, UL489

Parameter Comparison

Engineering Selection Recommendations

The 3D15UL is the direct substitute for the obsolete 3DU15L. Both components are manufactured by Altech Corporation and maintain identical electrical and mechanical specifications. The 3D15UL carries active product status with current manufacturing support, inventory availability (1232 pcs in stock), and full compliance with CE, cULus, and UL489 certifications. Selection of the 3D15UL ensures continuity of thermal-magnetic protection characteristics at 15A, 480V AC/DC with three-pole lever operation on DIN rail installations. Both parts maintain ROHS3 compliance and identical trade classification codes.

Frequently Asked Questions (FAQ)

Q: Can the 3D15UL directly replace the 3DU15L in existing installations?

A: Yes. Both components share identical electrical ratings (15A, 480V AC), mechanical configuration (3-pole, lever actuator, DIN rail mount), and regulatory certifications (CE, cULus, UL489). Direct substitution is valid for thermal-magnetic circuit protection applications.

Q: What is the primary reason for substitution?

A: The 3DU15L is classified as obsolete. The 3D15UL is the active production equivalent, ensuring ongoing availability and manufacturing support.

Q: Are there packaging differences between these parts?

A: The 3DU15L is supplied with dash packaging notation, while the 3D15UL is supplied in bulk packaging. This distinction does not affect electrical or mechanical performance.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 3DU15L and 3D15UL carry identical approval certifications: CE, cULus, and UL489. Both are ROHS3 compliant.

Q: What parameters must remain constant for substitution validity?

A: Current rating (15A), voltage rating (480V AC), pole count (3), actuator type (lever), mounting type (DIN rail), and regulatory certifications must all remain unchanged for substitution to be valid.
