ABB OT and OT PLUS disconnectors: The LED Controls guide
ABB OT and OT Plus disconnectors are manual switch-disconnectors used to safely isolate electrical circuits. Both are available from LED Controls. Standard OT models are robust and reliable for general isolation needs in control panels, machinery, HVAC, generators and more, offering clear visible separation for safety and maintenance.
The OT Plus range adds modern enhancements to this proven platform, covering current ratings from 16 A to 160 A with flexible 3-, 4-, 6- and 8-pole options to fit a wider variety of panel designs. Adjustable neutral behaviour on 4-pole models gives you improved efficiency with reduced power loss, and a more recycled materials in the device fabrication helps support sustainability.
Improved ergonomics, mounting options and accessory systems mean easier installation, while maintaining classic safety features such as padlockable handles and solid neutral switching. Because they combine flexibility, performance and future-proof design, OT Plus models are ideal for contemporary electrical installations.
