ESP 415T1 Surge Protection Series are a Combined Type 1 and 2 tested protector (to BS EN 61643) for use on the main distribution board, particularly
where a structural Lightning Protection System (LPS) is employed, for equipotential bonding. For use at boundaries up to LPZ 0 to protect against
flashover (typically the main distribution board location) through to LPZ 2 to protect electrical equipment from damage.
