The SPD2 3P+0 series is a surge protection device that safeguards components from transient overvoltage or surges that last micro-seconds by limiting the fault current to a load or the unit being protected. The majority of surges are caused by equipment being turned on or off within a facility. By limiting these surges, costly damage, downtime, repairs, and missed deadlines can be mitigated. The surge protection devices for the 3+0 configuration are available for 120 V to 600 V nominal voltage sub-distribution board applications.
