3WA air circuit breakers

The 3WA air circuit breakers are used as incoming feeder, tie, and outgoing feeder circuit breakers in electrical installations in industry, buildings and infrastructure applications.

They reliably protect electrical systems and machines from damage and, thanks to their robust design, outstanding quality and intelligent protective functions, prevent system downtimes, high downtimes and their consequential costs. Thanks to modular communication options, they can be integrated into electronic control, maintenance and energy management systems.

With three sizes for AC applications and one size for DC applications, 3WA air circuit breakers cover a power range from 630 A to 6,300 A. They are available in 3 and 4 pole versions. Simple and interactive selection aids as well as function packages ensure a significantly reduced complexity in planning and selection. Based on the current IEC 60947-1/-2 standards, the 3WA can be used worldwide.
