ABB SD203/50 2CDD283101R0050 3P DIN Switch Disconnector 50 A 400V

The ABB SD203/50 (article 2CDD283101R0050) is a 3-pole switch disconnector rated at 50 A, built to provide safe electrical isolation of three-phase circuits. Combining switching and isolation in a single unit, it serves as a practical solution for controlled disconnection and maintenance safety in three-phase installations.

Technical specifications:

• Series: SD203/50
• ABB article number: 2CDD283101R0050
• EAN: 4016779904223
• Type: Switch Disconnector
• Poles: 3P (three-pole)
• Rated current: 50 A

Features and benefits:

• Three-pole configuration disconnects all live phases in a single operation, supporting safe and complete circuit isolation.
• 50 A current rating accommodates a broad range of three-phase load and sub-distribution circuits.
• Integrates switching and isolating functions in one device, simplifying panel design and reducing component count.
• ABB article number 2CDD283101R0050 enables straightforward identification, ordering, and spare-parts tracking.

Applications:

• Isolation of three-phase motors and driven machinery before maintenance or servicing.
• Load disconnection in industrial control panels and three-phase distribution boards.
• Sub-circuit isolation in commercial or light industrial electrical installations.
• Main or sub-main disconnect in panel assemblies requiring a three-pole 50 A isolating switch.
