Description
The PGA-LS10 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 installed and positioned in switchboards 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. At a trip level setting of 1 on the Littelfuse PGR-8800 arc-flash relay, arcs greater than 3 kA within a 2 m half-sphere will be detected. 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.
