OT_C Change-over disconnects

OT_C change-over disconnects for a smooth and safe transition from one power source to another. In case of power source failure, whether planned or unplanned, a rapid switch to back-up power is often crucial.

Open transition manual change-over switches designed according to UL/CSA certification from 30 to 800 Amperes (UL).

 

Features and Benefits 

 

Reliable in extreme conditions

 

Change-over disconnect switches by ABB are extremely well suited for industrial applications. They are equipped with CTI (comparative tracking index) of over 600 V, making them great for use in tropical environments.

 

Energy efficiency

 

Our disconnects 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

 

16 to 3200 Amperes (IEC) manual change-over switches are available with three different transition types; Open, fast or closed.
