ABB (Asea Brown Boveri) is a power and automation technology group headquartered in Zurich, which was formed in 1988 from the merger of the Swedish ASEA and the Swiss BBC. As one of the world's leading technology companies in the fields of electrification products, robotics and drives, industrial automation and power grids, ABB also offers a complete family of switches, consisting of switch-disconnectors, diverter switches, motor-operated switch-disconnectors, load switches with fuses, motor-operated switch-disconnectors with fuses and cam switches. The switches are suitable for various applications, for example for motor controls, in switch panels and as main switches in various devices and machines.

ABB has now revised one of the most important switch components. In the all-in-one switch-disconnector series OT Plus, which is now available, the supplier sees nothing less than an innovative leap in the field of manual switch-disconnectors up to 160 amps. Thanks to the extended, overlapping rated current values in all frame sizes, the manual switch-disconnectors offer even more options for mixed loads and motor applications. The advanced technology used in the OT Plus range for distribution and sub-distribution applications is designed to provide outstanding protection from 16 amps to 160 amps with 3, 4, 6 and 8 pole options. Whether it's a simple application or a project that requires the highest level of reliability and safety, ABB says OT Plus gives users more options than ever before.
