AC Surge Protective Device

Surges may be caused by an indirect lightning strike but, the majority are caused by equipment being turned on or off within 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. The GHX Surge Protective Device (SPD) Series for branch circuits safeguards components from transient overvoltage or surges by limiting the fault current to a load or the unit being protected.


The DIN-rail mounted, pluggable module device offers a compact footprint for panel design flexibility as well as a quick and easy installation. With UL and IEC compliance in one component, the Surge Protective Device (SPD) Series reduces inventory needs and simplifies allocation of parts.
