Arc-Flash Detection  
PGA-LS30 Series  
Fiber-Optic Sensor  
Description  
The PGA-LS30 series Fiber-Optic Sensor is an arc-detection sensor that uses fiber to detect arcs anywhere along its length.  
This sensor is meant to be installed with the fiber along the back wall of switchboards to form the detection range across  
many compartments with just one sensor. The sensor is positioned to allow direct line of sight to all powered connections  
where an arc could develop. The sensor is capable of detecting the light from an arc flash from all angles. The detection  
radius is dependent on the arc power. The sensor is calibrated at the factory for 60 cm (24 in) of fiber in each monitored  
compartment. When using a fiber-optic sensor in compartments with less than 60 cm (24 in) of fiber, the sensitivity may  
have to be adjusted so that the sensor will detect arcs of 3 kA or more. This fiber-optic sensor and the arc-flash relay  
provide superior protection against the damaging effects of arc flashes and improve the lifespan of electrical equipment  
as well as the protection of personnel. This sensor is intended to be installed as part of an active arc flash mitigation  
system that uses Littelfuse arc-flash relays.
