ABB SD201/40 2CDD281101R0040 1P DIN Switch Disconnector 40 A 400V

The ABB SD201/40 (article 2CDD281101R0040) is a single-pole switch disconnector rated at 40 A. It combines the functions of a load switch and an isolator in one device, allowing a single circuit to be safely switched and fully disconnected from supply. This makes it a practical choice wherever independent circuit isolation is required.

Technical specifications:

• Series: SD201/40
• ABB article number: 2CDD281101R0040
• EAN: 4016779904094
• Type: Switch Disconnector
• Poles: 1P (single pole)
• Rated current: 40 A

Features and benefits:

• Single-pole (1P) format enables isolation of one circuit independently without interrupting adjacent circuits.
• 40 A current rating covers a wide range of standard branch circuit and load applications.
• Combines switching and disconnection in one unit, reducing the number of separate devices needed in a panel.
• Part of ABB's SD201 series, ensuring dimensional and functional consistency across multi-pole or parallel installations.

Applications:

• Manual isolation of single-phase branch circuits during maintenance or inspection.
• Main switch for individual electrical loads in distribution boards.
• Circuit isolation in residential consumer units and light commercial panels.
• Emergency shutdown switching for single-phase equipment.
