What is a Surge Pure – Surge Protection Device (SPD)?
A. A Surge Pure SPD is a passive electronic module which connects directly to the power lines, circuits and outlets of your building. When it senses that a transient voltage exceeds the normal operating level, it instantly turns “on”, suppressing the surge by safely diverting it to earth ground. It quickly turns “off” when the transient is gone and allows the normal power to continue flowing to your equipment.
