Why Choose the ABB SD204/25 Switch Disconnector?
The ABB SD204/25 is a compact and reliable four-pole switch disconnector designed for manual switching and isolation of electrical circuits. As part of the ABB SD200 series within the System pro M compact range, it provides dependable circuit control for distribution boards, switchboards, machinery and industrial electrical panels.
Designed in accordance with IEC/EN 60947-3, the SD204/25 provides electrical line isolation together with switching-under-load capability. Its four-pole configuration enables simultaneous disconnection of four conductors, making it particularly suitable for three-phase systems where the neutral conductor also needs to be switched.
With a rated current of 25 A and a rated operational voltage of 440 V AC, the SD204/25 provides robust switching performance for professional electrical installations. Clear ON/OFF contact-position indication, a sealable operating toggle and compact four-module DIN rail construction support straightforward installation, operation and maintenance.

Reliable Four-Pole Electrical Isolation and Circuit Control
Switch disconnectors provide a defined means of manually disconnecting electrical equipment from its supply. The ABB SD204/25 switches four poles together, making it particularly useful in three-phase plus neutral installations where all four conductors need to be disconnected as part of the switching and isolation arrangement.
The SD200 series combines compact modular construction with dependable switching performance, clear contact-position indication and compatibility with professional DIN rail assemblies. Appropriate upstream short-circuit and overload protection should be incorporated into the installation to provide the required protection for the switch disconnector and connected circuit.
Typical Applications
- Three-phase plus neutral electrical distribution boards.
- Industrial switchboards and control panels.
- Four-pole isolation of electrical circuits.
- Machinery and automation control systems.
- Commercial and industrial electrical installations.
- Building power distribution systems.
- Maintenance isolation of downstream three-phase equipment.
