2CDD281101R0025 ABB SD201/25 Switch Disconnector 1P 25 A

Why Choose the ABB SD201/25 Switch Disconnector?

The ABB SD201/25 is a compact and reliable single-pole switch disconnector designed for manual switching and isolation of electrical circuits. As part of the ABB SD200 series of modular control switches, it provides a straightforward means of disconnecting downstream equipment for maintenance and electrical safety applications.

Designed for installation in modular distribution boards and control panels, the SD201/25 combines a 25 A rated current with a 253 V AC rated voltage. Its DIN rail mounting format and single-module width make it particularly suitable where panel space is limited while providing clear ON/OFF switching of the connected circuit.

The SD201/25 is designed for switching under load and isolation in accordance with IEC/EN 60947-3. The operating lever can be sealed in both positions, while appropriate upstream short-circuit and overload protection should be provided as part of the electrical installation.

Reliable Electrical Isolation and Circuit Control

Switch disconnectors provide a defined means of manually connecting and isolating electrical circuits. The ABB SD201/25 is designed to allow downstream equipment to be disconnected from its supply for maintenance, servicing and operational control while providing a clear ON/OFF switching position.

Its modular construction makes the SD201/25 well suited to modern distribution boards, electrical enclosures and industrial control panels. The compact single-pole format occupies only one modular space, helping installers create efficient panel layouts while retaining convenient manual circuit isolation.

Typical Applications

• Electrical distribution boards and consumer units.
• Industrial control panels and switchboards.
• Manual isolation of single-phase electrical circuits.
• Building electrical installations.
• Machinery and automation control panels.
• Maintenance isolation of downstream electrical equipment.
