. . .
The Bourns Model 1250 Series is a general duty Surge Protective Device (SPD)
designed to protect high risk electrical service entrance and branch panels. This SPD is
intended to be installed at the front end of the installation, in the main switchboard, close
to sensitive terminals or in installations without LPS (lightning rods).
