The BSP3-20K series are 20kA surge protectors used in conjunction with LED drivers to provide protection against dangerous power transients.
They also protect electronic fluorescent, electronic HID ballasts, and induction lighting ballasts. Protection is provided from surges up to 20,000 amps.
Models are available for 277V and 480V power and three wire leads offer line-ground, line-neutral, and neutral-ground protection. It is particularly useful in 24/7 applications.
