The Edco PC642 series surge suppressor is a two-pair (four wire) module implementing three-stage hybrid technology. This module addresses over-voltage transients with gas tube and silicon avalanche components. In addition, sneak and fault currents ar e 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.
