PowerLogic A Series Arc Flash Protection— Introduction

Critical infrastructure depends heavily on an uninterrupted supply of electric power. The PowerLogic™ A125 and A3 arc flash protection devices help accomplish this and are used to improve safety and mitigate equipment damage. Schneider Electric is the pioneer in the field of arc flash protection with close to 50,000 arc flash systems and 600,000 sensors in service worldwide.

The A125 arc flash protection device offers rapid detection, within 2 milliseconds, to help mitigate damage and enhance safety. It supports up to 4 optical point sensors that can be strategically placed in key compartments.

The A3 arc flash protection device delivers ultra-fast 2 milliseconds arc detection, flexible multi-panel configurations, and scalable architecture supporting up to 50 sensors and 4 to 8 control outputs.

A125 and A3 arc flash protection devices are designed for use in low voltage (LV) and medium voltage (MV) switchgear. For more information, see A125 Arc Flash Protection and A3 Arc Flash Protection.
