ABB has redefined the standard for arc mitigation with its . This active protection system doesn't just wait for a breaker to clear—it attacks the fault at the source. What is the ABB UFES?

Fast-acting vacuum interrupters driven by micro gas generators that create the bolted short-circuit. Key Technical Specifications

The ABB UFES is an active protection device rather than a passive safety feature. It actively creates a safe condition in just a few milliseconds by short-circuiting the fault to ground. From the simple "Service Box" installation to complex digital retrofits with Relion relays, the UFES adapts to a wide range of low- and medium-voltage environments. abb+ufes+manual

If you meant an or other ABB electrical device whose model includes "UFES" (unlikely, but possible as a typo or internal code):

: The micro-gas generator inside the UFEA ignites. The expanding gas drives a moving contact pin forward at extreme velocity. ABB has redefined the standard for arc mitigation with its

Verify all mechanical bolting torques match the values specified by ABB.Confirm that the primary elements show no signs of transit damage or moisture. Insulation Testing

Because UFES is often integrated into larger arc‑protection schemes (such as ABB’s REA relay or the ArcLimiter solution), the manual also explains how to coordinate the detection electronics with external devices. From the simple "Service Box" installation to complex

: Can be installed in a top box, cable connection compartment, or as a separate draw-out unit. Retrofitting : For older systems, ABB offers a Service Box
