Smart Electric SPD50UL compact UL Type 1 Surge Protective Device safeguards single-phase electrical distribution systems against electrical surges, lightning strikes, and load switching.  The SPD50UL has a voltage of 120/240V, Single Phase, 50/60Hz, Maximum Surge Current of 50,000 Amps, and Short Circuit Current Rating of 200,000 Amps.

What is a Surge Protective Device? 

Surge Protective Device (SPDs) formerly known as Transient Voltage Surge Suppressor is a protective device that limit transient voltages by diverting or limiting surge current.  Having this device is cost-effective for it does prevent equipment damage caused by a sudden spike of voltage.  The Smart Electric SPD has an advantage in abnormal over-voltage & high fault current safety and thus ensures the industry’s safety and performance.
