DESCRIPTION

The Model PC642C Series surge suppressor is a dual-pair

(four wire) and the DRS Series is a single pair (two-wire)

DIN rail mount module implementing three-stage hybrid

technology. These modules protect against over-voltage

transients with gas tubes and silicon avalanche components.

In addition, sneak and fault currents are mitigated with

automatic resetting fuses (PTCs). The PTCs increase

resistance several orders of magnitude when over currents

are present and return to normal when over-currents are

removed. The ability to self-restore in this manner signiﬁcantly

increases suppressor performance and survivability.

FEATURES

• Lightning protection for low voltage signal lines

• Three-stage protection

• Plug-in and DIN rail mount modules

• Automatic recovery

• Nanosecond response time
