Vertiv Edco PC642 Series PC642C-036LC - surge protector

The EdcoPC642 surge-protective device (SPD) represents a two-pair (four-wire) module implementing three-stage hybrid technology. This SPD addresses over-voltage transients with gas tubes and silicon avalanche components. In addition, sneak and fault currents are mitigated with resettable fuses (PTCs). The PTCs increase resistance several orders of magnitude when over-currents exceed safe levels. A normal state resumes, when over-currents are removed. The ability to self-restore in this manner significantly increases suppressor performance and survivability.
