Description

Siemens SPD device provides whole house surge protection. This device takes up the space of two standard single pole breakers, but also includes two single pole breakers so you do not lose any space in your Load Center. Once connected in the panel, the SPD device protects the entire panel and all branch circuits from surges, not just the two circuits connected to the SPD. Initial clamping level is 240 Volts. LED's provide protection status notification. Siemens strongly recommends against the use of "used" breakers. The installation of used breakers in a Siemens panel will void the warranty on the panel. Siemens does not sell used breakers and has not approved any 3rd party sellers to do so.
