The arc is extinguished in less than 4 ms total—20 times faster than standard protection. abb+ufes+manual
The feeder circuit-breaker finally shuts down the resulting controlled earth fault current. Technical Specifications UFES | ABB - Core components Uses external detection devices like the ABB Arc
The manual provides critical instructions for installing, configuring, and maintaining one of the industry's fastest active arc-fault protection systems . By extinguishing internal arcs in less than 4 milliseconds , the UFES system significantly reduces the thermal and mechanical stresses that can destroy switchgear and endanger personnel. System Overview and Core Components Technical Specifications UFES | ABB - Core components
Three units that create the metallic short-circuit in less than 1.5 ms.
A micro-gas generator in the PSE creates a low-impedance path to ground, causing the arc voltage to break down.
