SURGE PROTECTION DEVICES
TYPE 2
SPD2 SERIES
Surges may be caused by an indirect lightning strike but, many are caused by equipment being turned on or off inside a facility.
These surges damage components costing money to repair or replace as well as create unplanned downtime resulting in unfulfilled orders, missed deadlines, unreliable systems and/or dangerous situations.
