Equivalent & Substitute Parts for 2DU50L Circuit Breaker

Part Overview

The 2DU50L is a thermal-magnetic circuit breaker manufactured by Altech Corporation, rated for 50A at 240V AC and 250V DC with lever actuation on DIN rail mounting. This product is classified as obsolete, necessitating identification of active equivalent models to maintain system continuity and ensure ongoing availability for replacement and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

The 2D50UL qualifies as a direct substitute for the 2DU50L based on the following critical parameters:

• Identical current rating of 50A
• Identical AC voltage rating of 240V
• Identical mounting type (DIN Rail)
• Identical breaker type (Thermal Magnetic)
• Identical actuator type (Lever)
• Identical number of poles (2)
• Identical approval agencies (CE, cULus, UL489)
• Identical RoHS3 compliance status
• Active product status, ensuring ongoing availability

The primary distinction is the series designation (UL versus L) and product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The 2D50UL is the appropriate substitute for the obsolete 2DU50L. Both components share identical electrical ratings, mechanical specifications, and regulatory certifications. The transition from the L series to the UL series represents a product line evolution within Altech Corporation's thermal-magnetic circuit breaker portfolio. The active status of the 2D50UL ensures component availability for new installations and replacement applications where the 2DU50L is no longer procurable.

Frequently Asked Questions (FAQ)

Q: Can the 2D50UL directly replace the 2DU50L in existing installations?

A: Yes. Both components are rated for 50A at 240V AC with identical DIN rail mounting, lever actuation, and two-pole configuration. All regulatory certifications (CE, cULus, UL489) and RoHS3 compliance are equivalent.

Q: What is the significance of the series designation change from L to UL?

A: The series designation reflects Altech Corporation's product line classification. The UL series represents the current active generation of this thermal-magnetic circuit breaker family, while the L series is obsolete.

Q: Are there packaging differences between these parts?

A: The 2DU50L is specified with dash packaging notation, while the 2D50UL is supplied in bulk packaging. Both are suitable for DIN rail installation.

Q: Do both parts carry the same regulatory approvals?

A: Yes. Both the 2DU50L and 2D50UL are certified to CE, cULus, and UL489 standards and comply with ROHS3 requirements.

Q: Is DC voltage rating a consideration for substitution?

A: The 2DU50L specifies 250V DC rating. The 2D50UL substitute data does not explicitly state DC voltage rating. Verification of DC application requirements against the 2D50UL datasheet is necessary for DC-specific applications.
