Energy efficiency
Our switches come with a real one pole construction in even higher ratings (one line per power line), creating savings in terms of energy consumption by reducing power loss. A single terminal per pole across the entire range also eliminates the need to use additional fixing sets to do connections.
Space saving
The modular and flexible construction, which can even include an adjustable periscopic shaft, allows for different arrangements of the poles and handle, providing you with the opportunity to create unique space saving solutions for your customers.
Global availability
To complement our wide range of manual change-over switches, we also offer open transition manual change-over switches designed according to UL/CSA certification standards in a power range from 160 to 800 Amperes.
Motorized OTM Series
Uninterrupted power supply with motorized functionality
ABB offers a wide variety of open transition motorized change-over switches from 40 to 3200 Amperes in range. All of our motorized change-over switches come equipped with a cover with clear operating instructions and improved motor operator performance.
Easy installation

ABB motorized change-over switches are fast and easy to install. The voltage sensing connectors have been designed to save time, as there is no need to drill holes into the busbars. Also, the control and power cables are screw mounted, providing a safe and secure connection that stays tight even during transportation.
Safety and protection
Our switches come equipped with a comprehensive range of inbuilt safety features such as mechanical interlock, which ensures the isolation of the two asynchronous power supplies. This eliminates risk of short-circuiting between them. The motorized change-over switches are also equipped with a handle for manual operation in case of emergency.
Reliable in extreme conditions
Ensuring a high performance level for you is of the utmost importance to us. In change-over applications where the loaded switch may need to be operated remotely, adequate durability has been ensured by testing against the IEC 60947-6-1 standard in the specification of endurance requirements.
Space saving
ABB provides compact and cost-effective components for any and all installations. On average, our motorized change-over switches are 20% smaller than other similar products on the market.
