Change-over Disconnects
OTC and OT_C change-over disconnects provide a smooth and safe transition form 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 to meet UL 60947-4-1 from 20-100 Amperes and UL1008 from 200-800 Amperes.
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.
Meets design standards
With a UL1008 listing from 200 to 800 Amperes, the OT_C manual change-over switch is rated for use in emergency backup power systems.
