The PGA-LS10-01B series arc-detection point sensors are capable of detecting light from every angle in front of them due to the shape of the cylindrical lens on the front of the sensor. These sensors are intended for use in combinatiton with AF0025 Arc-Flash relay and positioned in tight space, to give them direct line of sight to all powered connections where an arc could develop. The detection radius is dependent on the arc power. The PGA-LS10-01B has a detection area of a 2 m (7 ft) half-sphere for arcs of 3 kA or more. These point sensors and arc-flash relays provide superior protection against the damaging effects of arc flashes and improve the lifespan of electrical equipment as well as the protection of personnel.
